Mouth ulcers, also known as canker sores or aphthous stomatitis, are painful lesions that appear on the mucous membranes of the oral cavity. They have an oval or spherical form, a white or yellow centre, and a crimson border. Their size and intensity might vary. It is believed that a combination of genetic, environmental, immunological, and microbiological factors contribute to mouth ulcers, even if the exact aetiology is often unknown. Common factors include hormonal changes, certain foods, stress, trauma, and nutritional deficiencies. Without therapy, the issue normally goes away on its own in a week or two. However, medical interventions such as topical treatments, oral medications, or lifestyle modifications may be necessary in severe or ongoing circumstances to.
Mouth ulcers are painful lesions that form on the mucous lining of the mouth, including the cheeks, gums, tongue, and lips. They are sometimes referred to as canker sores or aphthous ulcers. Usually round or oval in shape, these ulcers have a crimson border around a white or yellowish centre. Despite not being communicable, they can be extremely uncomfortable, particularly when eating, talking, or brushing your teeth. Although the precise aetiology of mouth ulcers is unknown, it is thought that a number of factors, including stress, oral trauma, hormonal shifts, particular foods, and nutritional deficiencies, have a role in their development. The majority of mouth ulcers go away on their own in one to two weeks, however severe or recurring situations may need medical care to control symptoms and stop them from happening again. Managing these frequent oral disorders requires an understanding of the underlying causes and available treatments.

1.2 Mouth Ulcer Characters
Mouth ulcers come in a variety of forms, each with unique traits:
Minor Ulcers of the Aphthous
These are the most prevalent kind, usually round or oval in shape, with a red border and a white or yellow centre, and small (less than 1 cm in diameter). They rarely result in serious consequences and typically heal without leaving scars in 7–10 days.
Major Aphthous Ulcers:
These ulcers are deeper than small ulcers and larger (more than 1-2 cm). They can hurt more and take longer to heal—up to two to four weeks. Large ulcers can occasionally be an indication of an underlying medical issue and are frequently linked to scarring.
Herpetiform Aphthous Ulcers:
These ulcers are tiny (about 1-2 mm) and numerous (typically in clusters). Anywhere in the mouth, they can develop, and they can combine to create bigger ulcers. They have nothing to do with the herpes simplex virus, despite being referred to as “herpetiform.”
Traumatic Ulcers:
Damage or trauma to the mouth, such as biting the inside of the cheek, brushing too vigorously, or dental procedures, is what causes these ulcers. Once the injury is avoided or handled, they usually heal on their own.
Viral Ulcers:
Although other viruses can potentially cause them, viral infections like the herpes simplex virus (cold sores) are the source of these ulcers. They frequently reoccur, particularly in people with compromised immune systems, and can manifest as one or several lesions.
Fungal Ulcers:
Especially in immunocompromised people or those who wear dentures, fungal infections like candidiasis (thrush) can cause these ulcers. The ulcers may look like painful, red sores or they may have a white coating.
The following are the levels of human pathogenic mouth ulcers that are classified as acute, high, and moderate risk:
Oral mucosal lesions, commonly referred to as mouth ulcers, can be categorised according to the likelihood that they are associated with human pathogenic diseases. We generally assess “acute risk” mouth ulcers according to their aetiology, severity, and potential for injury. The following is a classification:
Risk: Low for minor aphathous stomatitis (canker sores).
These are tiny, excruciating ulcers that usually go away on their own in a week or two. Generally speaking, they don’t pose significant or persistent health problems.
Moderate risk of major aphathous stomatitis.
In addition to being deeper, bigger, and taking longer to cure, these ulcers frequently cause excruciating pain. Although they are typically not associated with systemic disorders, their persistence may be a sign of an immune system impairment or an underlying ailment such as Crohn’s disease.
Virus Infections Caused by Herpes Simplex:
Risk: Elevated. Because of their propensity to reoccur, their painful nature, and their ease of spread, HSV-related ulcers—also known as cold sores—are particularly concerning. Serious problems can arise from HSV in immunocompromised people.
The risk of oral candidiasis (throshing) is high.
An overabundance of Candida fungi can cause oral candidiasis, which can manifest as painful sores or ulcers. It is particularly risky for people with weakened immune systems because, if left untreated, it can result in systemic infections.
Traumatic Ulcers: Varying Risk.
These result from mechanical injuries, such as cheek biting or denture irritation. The majority resolve on their own, but improper management might result in infections or other problems.
Squamous Cell Carcinoma (Oral Cancer):
The risk of oral cancer, or squamous cell carcinoma, is extremely high. In people who smoke or have a history of alcohol consumption, persistent, non-healing ulcers that do not go away after three weeks may be a sign of oral cancer. If not identified and treated quickly, this poses a very significant acute danger.
Systemic Conditions (e.g., Lupus, Behçet’s Disease):
Moderate to High Risk Depending on the particular ailment and how it is treated, mouth ulcers can range in severity and risk as a symptom of systemic disorders.
1.3 The Human Body
Mouth ulcers, sometimes referred to as canker sores, can have a variety of negative effects on the body, especially on the mouth region. The main consequences consist of:
Pain & Discomfort:
The ulcers may cause severe pain, particularly while speaking, eating, or drinking, which can interfere with everyday activities and make it hard to keep your mouth clean.
Inflammation:
Discomfort in the surrounding tissues may result from the ulcer’s surrounding area becoming red, swollen, and inflamed.
Having trouble eating and drinking:
People who have mouth ulcers may avoid certain meals, particularly those that are hot, spicy, or acidic, as this can make the pain worse.
Possible Infection:
A bacterial infection could occur if the ulcer is not treated or becomes inflamed. This could delay the healing process and result in further discomfort.
Stress and fatigue:
Chronic mouth ulcers or recurrent outbreaks can lead to stress, which can impair general health and occasionally result in exhaustion because of the discomfort.
Increased Sensitivity:
The afflicted oral region becomes more sensitive to touch, making everyday tasks like eating and speaking challenging. Mouth ulcers often heal on their own in a week or two, but if they are frequent or persistent, they may indicate a medical condition such a gastrointestinal problem, autoimmune disease, or vitamin deficiency. It might be wise to see a medical expert for assessment if ulcers are common or extremely painful.
1.4 Classification of Mouth Ulcer
Various forms of mouth ulcers can be distinguished by their traits, aetiology, and severity. The primary categories consist of:
Canker sores, or aphathous stomatitis:
Less than 1 cm in diameter, minor aphthous ulcers are round or oval in shape, with a red border and a white or yellow centre. They often heal without leaving scars in 7–10 days. Larger, deeper ulcers (greater than 1 cm) that can cause discomfort and take weeks to heal, often leaving scars, are known as major aphthous ulcers.
Herpetiform Aphthous Ulcers:
A large number of tiny ulcers that may develop in groups. Usually extremely painful, they go away in a week or two. Injuries or irritations, such as biting the cheek, dental treatments, or poorly fitting dentures, can result in traumatic ulcers. Usually, after the irritation is eliminated, they recover.
Herpes simplex virus (HSV) Ulcer
The herpes simplex virus, typically HSV-1, is the cause of these ulcers, which are painful, blister-like, and frequently clustered. Although they are more frequently found on the lips, they can occasionally show up inside the mouth.
Candidiasis (Oral Thrush):
A fungal illness, Candida can cause oral ulcers that frequently have a white coating. Those with weakened immune systems frequently experience this, which can be uncomfortable.
Lichen Planus in the mouth:
An inflammatory disease that can result in painful oral ulcers or white, lacy patches. Being a chronic illness, it might need to be managed by a doctor.
Erythema Multiforme:
An uncommon hypersensitivity reaction that can result in mouth blisters and ulcers. Infections such as the herpes simplex virus are frequently linked to it.
Systemic diseases-related ulcers:
Recurrent mouth ulcers are a sign of several illnesses, including Crohn’s disease, Behçet’s disease, and systemic lupus erythematosus (SLE).
Cancerous Ulcers:
Malignant mouth ulcers may indicate oral cancer. Pain, bleeding, or trouble swallowing are some of the additional symptoms that may accompany these ulcers, which are often irregular and persistent.
1.5 Causes of Mouth Ulcer –
The following are some of the causes of mouth ulcers:
Trauma or injury includes things like biting the inside of the cheek or lip, burns from hot food or beverages, or irritation from braces, abrasive teeth, or poorly fitted dentures.
Infections:
Viral infections: cold sores can be caused by the Herpes simplex virus (HSV), and mouth ulcers can occasionally result from the varicella-zoster virus, which causes chickenpox.
Bacterial infections:
Poor oral hygiene can cause several bacterial infections, which can result in ulcers.
Fungal infection:
Candida (thrush) infections are fungi that can cause mouth ulcers, especially in those with weakened immune systems.
Nutritional Deficiencies:
Iron, folic acid, zinc, vitamin B12, and other vitamin and mineral deficiencies can all lead to the development of mouth ulcers.
Stress and Hormonal Changes:
The risk of developing mouth ulcers may be raised by emotional stress or hormonal changes (such as those that occur during menstruation or pregnancy).
Autoimmune Conditions:
Recurrent mouth ulcers can be a symptom of the systemic consequences of conditions like lupus, Behçet’s disease, Crohn’s disease, and coeliac disease. Mouth ulcers may result from allergic reactions to specific foods, drugs, or dental products (such as toothpaste containing sodium lauryl sulphate).
Genetic Factors:
People may be more susceptible to getting mouth ulcers if they have a family history of them.
Medication:
Mouth ulcers are a side effect of some medications, such as beta-blockers, nonsteroidal anti-inflammatory drugs (NSAIDs), and chemotherapy therapies.
Inadequate oral hygiene:
Not brushing and flossing enough can cause bacteria to accumulate, raising the risk of ulcers and infections.
Underlying Medical Conditions:
Recurrent or severe mouth ulcers can be caused by illnesses like Epstein-Barr virus, ulcerative colitis, or HIV/AIDS.
An ulcer brought on by an infection or illness, usually by bacterial, viral, or fungal pathogens, is referred to as a pathogenic ulcer. These ulcers are frequently linked to underlying problems including infections, poor circulation, or autoimmune diseases. They can appear on the skin, gastrointestinal tract, or mucous membranes, among other places.
Some common forms of pathogenic ulcers are as follows:
Peptic ulcers:
These lesions in the stomach or duodenum are brought on by Helicobacter pylori infections or long-term use of nonsteroidal anti-inflammatory medicines (NSAIDs).
Venous ulcers:
these are caused by inadequate blood flow in the legs and are frequently associated with chronic venous insufficiency.
Diabetic ulcers:
caused by poor circulation and neuropathy, these ulcers usually appear on the feet or lower limbs of diabetics.
Pressure ulcers (bedsores) –
Long-term pressure on the skin can result in pressure ulcers, also known as bedsores, which are frequently seen in bedridden or immobile people.
When people, animals, or ecosystems come into touch with or interact with environmental elements like air, water, soil, or chemicals, this is referred to as “environment exposure.” It can involve being exposed to both natural and artificial factors that could have an impact on one’s health, happiness, or the quality of the surroundings.
For example:
For instance, exposure to the human environment can occur through contact with hazardous substances, ingesting tainted water, or breathing in polluted air. The effects of temperature variations, pollution, or habitat degradation on plants, animals, and ecosystems might be referred to as ecological exposure. When evaluating hazards and putting policies in place to safeguard the environment and public health, environmental exposure research is crucial. “Environmental exposure” in the context of mouth ulcers can refer to a number of variables that could cause the ulcers to form or worsen. These may consist of:
Dietary factors:
Consuming foods or beverages that are acidic or hot, which can irritate the lining of the mouth and cause ulcers.
Chemical irritants:
Contact with substances that can irritate or heighten sensitivity, such as those included in mouthwashes or toothpaste (such as sodium lauryl sulphate).
Environmental stressors:
Stress, whether physical or emotional, can impair immunity and increase the risk of developing mouth ulcers.
Infections:
The formation of mouth ulcers may result from exposure to bacterial, fungal, or viral infections (such as the herpes simplex virus).
Trauma:
Injuries to the mouth that happen by accident, like biting the inside of the cheek, or irritation from braces or dental procedures, can result in or worsen ulcers.
Immune system weakness:
Mouth ulcers can occur more frequently or with greater severity when the immune system is compromised. A robust immune system normally aids in maintaining the body’s defences, including the mouth, where it can fend off irritants or diseases. Ulcers are more likely to occur when the body is unable to control typical oral bacteria and other variables because of immune system impairment, which can be brought on by stress, illness, certain drugs, or underlying illnesses like HIV/AIDS.
Consider the following to help a compromised immune system and avoid or treat mouth ulcers:
Good oral hygiene:
Maintaining proper oral hygiene involves brushing your teeth on a regular basis and using a gentle mouthwash without alcohol to lessen irritation.
Healthy eating:
Put an emphasis on a well-balanced diet high in vitamins, particularly zinc, vitamin C, and B vitamins, which promote healing and immune system function.
Hydration:
To maintain a moist and reduced mouth, drink lots of water.
Avoid irritants:
Acidic or spicy foods can exacerbate ulcers.
Stress management:
Since stress can affect the immune system, try to minimise it. Speak with a medical professional: It’s critical to consult a doctor if ulcers worsen or persist since there may be underlying issues that require care.
2.Climate:
Mouth ulcer formation and severity can be influenced by climate in a number of ways. The mouth and immune system can be affected by changes in environmental factors like temperature and humidity, which may cause new mouth ulcers or exacerbate preexisting ones.
The Impact of Climate on Mouth Ulcers:
Low Humidity and Dry Conditions:
Xerostomia, or dry mouth, can be brought on by dry, arid conditions or cold, low-humidity weather. The risk of developing ulcers is increased when the mouth is dry because it is more likely to become irritated and the mucous membranes may be more vulnerable to damage. Dehydration brought on by a dry climate can also impair the body’s capacity to fight infections and heal, which may be a factor in the development of mouth ulcers.
Hot and Humid Climates:
Excessive perspiration, dehydration, and an electrolyte imbalance are all consequences of hot, humid weather. Additionally, these circumstances may result in a compromised immune system, potentially raising the incidence of mouth ulcers. To cool off in such climates, people may also be more likely to eat spicy or acidic meals, which can irritate the oral mucosa and cause ulcers in those who are susceptible.
Seasonal Changes:
People may encounter more allergens or undergo immune system changes throughout seasonal changes, such as from winter to spring or summer to fall, which could result in situations that could aggravate mouth ulcers. For instance, the winter months may result in increased stress or vitamin deficiencies (from less sunlight and fresh vegetables), which can weaken the immune system and induce mouth ulcers.
Allergens and pollution:
Environmental elements such as dust, pollen, and other irritants can worsen mouth ulcer symptoms or raise their risk of developing in cities with high pollution levels or during allergy seasons.
Handling Dental Ulcers in Various Climates:
Remain hydrated: To avoid drying out, especially in hot or arid regions, drink lots of water. Protect your lips and mouth: In cold, dry weather, apply lip balm or a moisturising gel to avoid chapping.
Air humidification:
To avoid mouth dryness in arid settings, think about utilising a humidifier.
Avoid irritants:
Pay attention to what you eat and steer clear of foods that are extremely acidic or spicy, especially in hotter areas.
1.6 Symptoms of Mouth Ulcer: -
Usually appearing on the soft tissues inside the mouth, such as the inside of the lips, cheeks, gums, or tongue, mouth ulcers (also called canker sores) are tiny, excruciating sores. The degree and kind of ulcer will determine the symptoms, however typical indications include:
Typical signs of oral ulcers
Pain or discomfort:
Pain or a burning feeling, particularly during eating, drinking, or speaking, is one of the main signs of mouth ulcers. The severity of the pain varies according to the ulcer’s size and location:
Sore or Lesion:
Usually, there is a noticeable white or yellowish ulcer with an inflammatory or red border. The ulcer could be a few millimetres in size or it could be a larger, more painful sore.
Swelling:
The surrounding tissue may seem swollen or inflamed, which would increase the ulcer’s pain and visibility.
Sensitivity:
Foods and beverages that are hot, spicy, salty, or acidic may cause severe discomfort for the ulcer.
Difficulty Eating or Drinking:
People who have mouth ulcers may find it difficult to eat or drink some foods because of the pain, especially coarse or irritating foods.
A tingling or burning sensation: Before
Periodic Fever:
When ulcers are a symptom of a more serious problem, such a viral infection or a systemic illness, there may occasionally be a slight fever or a general malaise, or feeling poorly.
Tender or Swollen Lymph Nodes:
If an underlying infection is the cause of the ulcers, the surrounding lymph nodes may swell.
Extra (Least Common) Symptoms:
Recurrent Ulcers: Stress, particular meals, or other triggers may be the cause of recurrent mouth ulcers, which can occur in cycles for some people.
Multiple Ulcers:
Some people may experience several ulcers at once, frequently in various parts of the mouth, especially those who have autoimmune illnesses or specific infections.
Although they can be uncomfortable, mouth ulcers can be managed and healed in a number of ways. Here are a few alternatives for treatment:
Topical Treatments:
You can numb the region and lessen pain by using over-the-counter gels or creams like benzocaine (Orajel). Inflammation may also be lessened by hydrocortisone creams.
Saltwater Rinse:
An ulcer can be cleaned and its swelling reduced by gargling with warm salt water.
Steer clear of irritating foods:
foods with a rough texture, acidity, or spice might aggravate the ulcer. Eat only blander, softer foods while the ulcer heals.
Oral Pain Relievers:
Acetaminophen or ibuprofen, which are available over-the-counter, can be used to assist manage pain.
Maintain Proper Oral Hygiene:
Using an antimicrobial mouthwash and gently brushing with a soft toothbrush will help to improve healing and avoid infections.
Aloe Vera or Honey:
Because of their anti-inflammatory qualities, applying aloe vera gel or honey directly to the ulcer may help lessen discomfort and encourage healing.
Vitamin Supplements:
Supplements may be helpful if a vitamin deficit (such as iron, folate, or B12) is the cause of your ulcers. You should see a doctor if your ulcer is severe, chronic, or accompanied by other symptoms like fever. This is because it may indicate an underlying disease.
Although most mouth ulcers go away on their own in 7 to 14 days, these therapies can help control symptoms and hasten healing. The term “topical ulcer disease” describes the development of ulcers, sometimes known as “open sores,” on the skin or mucous membranes for a variety of reasons. These ulcers may be caused by underlying systemic disorders, inflammatory conditions, infections, or trauma. However, ulcer disease usually entails tissue disintegration, resulting in discomfort and healing difficulties, whereas the term “topical” usually refers to surface level concerns.

CONCLUSION: -
To sum up, research on ulcers has greatly improved our knowledge of the intricate processes that lead to ulcer development, such as the roles of nonsteroidal anti-inflammatory medicines (NSAIDs), Helicobacter pylori infection, and the mismatch between mucosal defence and gastric acid output. Although the focus of treatment has changed to include a mix of proton pump inhibitors, antibiotics, and lifestyle changes, obstacles still exist in creating more efficient, customised treatments for ulcer patients. Enhancing early detection techniques, finding new therapeutic targets, and comprehending the long-term impacts of ulcer treatment on general gastrointestinal health should be the main goals of future study. New drug delivery technologies and personalised medicine developments have enormous potential to improve the prognosis and quality of life for ulcer patient
