A mouth ulcer is an ulcer that develops on the oral cavity's mucous membrane. Mouth ulcers are fairly common and can be caused by a variety of diseases and mechanisms, although most of the time there is no major underlying reason.
Local trauma (such as rubbing from a sharp edge on a damaged filling) and aphthous stomatitis ("canker sores"), a disorder defined by the repeated production of mouth ulcers for mostly unknown reasons, are the two most typical causes of oral ulceration. While healing takes place, mouth ulcers frequently cause pain and discomfort and may change a person's eating habits (e.g., avoiding acidic, salty, or spicy foods and beverages).
They may form individually or multiple ulcers may appear at once (a “crop” of ulcers). Once formed, the ulcer may be maintained by inflammation and/or secondary infection. Rarely, a mouth ulcer that does not heal may be a sign of oral cancer.
Epidemiology
Uncertainty surrounds the frequency and epidemiology of MU. They can affect people of any age, but it has been noted that patients between the ages of 20 and 40 are more likely to experience them. Up to 66% of young adults provide a history that is consistent with MAU. One in five members of the general population are thought to be affected over their lifetimes.
Mouth ulcer types
Three basic varieties of mouth sores exist:
Eighty percent of all cases of minor ulcers are of this sort. Small (2-8 mm in diameter), they normally heal on their own in 10 to 14 days. Scarring won't occur as a result of a little ulcer.
Major ulcers typically have a raised or uneven border and are deeper and larger than mild ulcers. Typically, they are 1 cm
Herpetiform ulcers form as multiple, pinhead-sized sores. The number of ulcers can range from five to 100. These tiny ulcers often fuse together to form larger, irregular shaped sores, which are very painful. Around 5-10% of mouth ulcers are herpetiform. Herpetiform ulcers are not related to the herpes virus.
Recurrent Herpetiform ulcers
Risk factors
A risk factor is something that increases your chance of developing a condition or disease. Risk factors for developing mouth ulcers include:
Gender: Women experience more incidences of ulcers due to their hormone changes during their monthly cycle.
Heredity: The tendency to get mouth ulcers runs in families.
Stressful lifestyle: Stress is a known factor for developing mouth ulcers.
Diet: Excessive intake of coffee, chocolate, strawberries, almonds, cheese and peanuts can increase your risk of ulcers.
Causes of Mouth ulcer
Mouth ulcers can be caused by a wide range of factors including:
Accidental biting of the inside of your cheek
Injury from a toothbrush (such as slipping while brushing)
Constant rubbing against misaligned or sharp teeth
Constant rubbing against dentures or braces
Poor oral hygiene
Burns from eating hot food
Irritation from strong antiseptics, such as a mouthwash
Oral thrush infection
Viral infections such as the herpes simplex viral infection (cold sore)
Reaction to certain medications
Skin rashes in the mouth (for example, lichen planus)
Autoimmune diseases
Underlying gastrointestinal disease such as Crohn’s disease
Oral cancer
Mouth ulcer symptoms
Ulcers can be painful, and the pain can be made worse by food, drink, and poor oral hygiene.
Herpetiform ulcers lesions may:
Appear as extremely painful ulcers in the mouth
Recur very quickly, so infections seem continuous
Increase in size, eventually coming together to form a large, ragged ulcer
Take 10 or more days to heal
Appear anywhere in the mouth
They tend to be found in more females than males and are more common in older adults.
Symptoms of minor and major ulcers include:
One or more painful sores that may appear on the cheeks, the roof of the mouth, or the tongue
The appearance of round lesions that have red edges and are yellow, white, or gray in the middle
During more extreme outbreaks of mouth ulcers, some people may experience fever, sluggishness, and swollen glands.
Complications
Complications may include:
Cellulitis of the mouth, from secondary bacterial infection of ulcers
Dental infections (tooth abscesses)
Oral cancer
Spread of contagious disorders to other people
Diagnosis
Mouth ulcers are usually easy to diagnose. Occasionally biopsy is performed, particularly if considering cancer. It should be taken from the indurated edge of an inflammatory ulcer or from an inflamed but non-ulcerated site.
Aphthous ulceration has varying and nonspecific features
Oral lichen planus and erythema multiforme may show a lichenoid tissue reaction
If the patient has frequent, prolonged or large ulcers, or is unwell, the following tests may be done to assess general and gastrointestinal health.
Bacterial and viral swabs from the ulcers
Complete blood cell count
Iron, B12, and folate
Coeliac antibodies
Fecal calprotectin (a test for inflammatory bowel disease)
Selected patients may undergo further assessment including endoscopy if there is suspicion of inflammatory bowel disease.
If specific toothpaste or food is thought to precipitate ulcers, allergy tests including prick tests, patch tests and specific IgE testing may be performed. The results can be difficult to interpret.
Treatment of Mouth ulcer
Most mouth ulcers get better on their own within 1 to 2 weeks. Until your ulcer heals:
Use a soft toothbrush to reduce further damage
Rinse your mouth with a warm salt-water mouthwash
Avoid foods that make the pain worse, such as spicy or acidic food
Choose softer foods that are less likely to make the ulcer feel worse
Use a straw to drink cool (not hot) liquids so they don’t touch ulcers in the front of your mouth
Take paracetamol for pain relief
Medicines for mouth ulcers
If your mouth ulcer is causing a lot of pain or not healing, there are medicines that can help relieve pain, protect the ulcerated area, reduce inflammation or prevent further infection. The choice of medicine will depend on how much discomfort you are experiencing and the cause of the ulcer. Talk to a pharmacist about the following options:
Antiseptic mouthwashes- (such as chlorhexidine) are used to prevent infection by stopping the build-up of bacteria
Protective pastes (such as Orabase®) act as a protective covering when applied to the ulcer
Steroid-containing pastes (such as Kenalog in Orabase® and Oracort®) help to relieve pain, inflammation (redness), discomfort and speed up healing
Local analgesics (pain relievers applied to the area) come in the form of a mouthwash, spray, gel or ointment and offer pain relief to the area, in and around the ulcer
Antiviral creams are available if your mouth ulcer is caused by the herpes simplex virus (also called cold sores or fever blisters).
Your GP may prescribe a stronger medication to treat severe, recurrent or infected mouth ulcers.
Home remedies for mouth ulcers
Turmeric with honey: Take a pinch or two of turmeric and mix it with honey to form a paste and apply it on the ulcer. Turmeric is known as a natural antiseptic, which can help to prevent infection at the ulcer site. Honey acts as a humectant and hastens the formation of new tissues and rapid healing.
Holy basil: You can either chew 4-5 leaves of Tulsi or can have a cup of Tulsi green tea, two to three times a day, to improve the healing of ulcers. Tulsi, by virtue of its adaptogenic properties, helps the body to adapt to the illness and fight inflammation.
Coconut oil and coconut water: According to Ayurveda, drinking tender coconut water reduces heat in the body and hasten the healing of mouth ulcers. Applying coconut oil on the ulcer prevents further scarring and helps in faster new tissue generation.
Licorice: Liquorice is a well-documented remedy for mouth ulcers in the Ayurveda. Studies show that the application of licorice paste or powder on the ulcer reduces pain, redness, and swelling due to its inherent anti-inflammatory properties.
Baking soda: Make a paste of baking soda with water and directly apply it on the ulcer. Baking soda neutralizes the acid formed at the site of the ulcer and therefore provides quick pain relief.
Important note: Mouth ulcers resolve within 5-7 days. If you find a persistent mouth ulcer which does not cause much pain, it could be a sign of cancer or any other complication. Such patients are recommended to consult a physician.
Avoiding mouth ulcers
You might be able to lower your chance of developing mouth ulcers by:
Keeping your lips as sterile and wholesome as you can
Using superior toothbrushes (to reduce the risk of damage to your mouth)
Consuming a healthy diet that is high in vitamins A, C, and E and contains fresh fruit and vegetables (to lessen the risk of mouth cancer)
visiting your dentist regularly.
