Canker Sore Under the Tongue: Why It Happens and How to Treat It?
A canker sore under the tongue, or a sublingual canker sore, is often an annoying issue. Not only under the tongue, these sores also appear on the inside of the cheeks and at the base of the gums.
Starting with the appearance of a yellowish-white open sore, a canker sore can progress into something painful. Follow an in-depth discussion about the causes and effective solutions for canker sores under the tongue in the following article.
Causes of Canker Sores Under the Tongue

As one of the types of painful mouth sores, the canker sore that appears under the tongue does not occur without a reason. Here are several causes of oral canker sores.
Mechanical trauma, such as an accidental bite, friction from dentures, or brushing too hard, can cause a wound under the tongue and trigger a canker sore.
Psychological and emotional stress are often associated with the appearance of canker sores, including in the sublingual area. Stress can affect the immune system and make the mouth more susceptible to canker sores.
Deficiencies in vitamin B12, iron, and folic acid can also trigger canker sores. These deficiencies interfere with the formation of healthy mucosal cells in the mouth.
Allergies to certain foods, food additives, or chemicals in toothpaste and mouthwash can cause an inflammatory reaction that brings on canker sores.
Diseases such as Crohn's disease, celiac disease, or autoimmune disorders like lupus can also cause canker sores in various areas of the mouth, including under the tongue.
Oral infections caused by the Herpes simplex virus or bacteria can lead to wounds and canker sores. Fungi, such as Candida, are also known to cause canker-like lesions.
If you see symptoms of a sublingual canker sore, such as an open sore with red borders, pain in the affected area, inflammation, and difficulty eating, you should take proactive steps immediately so the symptoms do not worsen.
How to Handle Canker Sores Under the Tongue?
The good news is that you can handle this condition starting with home methods. However, if the condition worsens and does not heal after a long time, you need to seek medical help. Several ways to address canker sores under the tongue:
1. Salt Water Rinse

Salt is popular for its natural antiseptic properties. Mixing one teaspoon of salt with a cup of warm water to rinse your mouth will facilitate the process of reducing inflammation and infection as well as wounds caused by injury in the mouth.
Don't forget to spit out the water after rinsing – it is not to be swallowed.
2. Ice Cubes

To soothe swelling, you can also use an ice cube compress. Doing this provides a temporary numbing effect, so the pain is slightly reduced.
Not only that, ice also slows down inflammation and swelling by reducing blood flow to the area.
3. Avoid Spicy and Acidic Foods

Eating spicy, oily, and acidic foods will only worsen a canker sore. In fact, you should avoid eating tomatoes, citrus fruits, and other spiced foods during the recovery period.
Ignoring this will only aggravate the irritation and also hinder the progress of recovery.

5. Vitamins for Canker Sores and Zinc

If the canker sore is a result of nutritional deficiency, consuming vitamin B12 and zinc supplements can help accelerate healing.
This happens because both these minerals are important in the maintenance and repair of oral mucosal tissue.
6. Aloe Vera Gel

Gel from aloe vera has anti-inflammatory properties, making it ideal as a home treatment for oral canker sores, including under the tongue.
You can apply the gel to the wound area so that the pain subsides and healing happens faster.
7. Consultation with a Doctor

If the canker sore persists for more than two weeks, or if you experience a very large or bleeding canker sore, or it occurs alongside other symptoms such as fever or body aches, consult a doctor immediately.
The doctor can prescribe antiseptic medication, topical steroids, or other treatments that are more specific according to the cause of the canker sore. Do not take canker sores that appear lightly.
Without proper handling, this condition can be an indicator of more serious health problems.
Maintaining oral health is very important, especially when fluid intake is reduced and the potential for oral irritation increases.
Keeping Alang Sari Cool at home is useful for preventing canker sores and addressing them quickly, maintaining oral health and ensuring your mouth remains comfortable.
So, do not underestimate canker sores, especially those under the tongue. Make sure to always be prepared with first aid when a canker sore comes!
