What are canker sores (mouth sores)?

Oral canker sores, or sores in the mouth, are small ulcerative lesions that appear on the oral mucosa, usually on the inside of the lips, cheeks, tongue or gums. These are usually yellowish-white in color and are surrounded by a red and inflamed area. Mouth sores can vary in size and, although medically harmless, can be extremely painful, especially during chewing or speaking.


Causes of canker sores (mouth sores)

Although the exact causes of canker sores are not fully understood, there are several factors that can contribute to their appearance:

  • Mechanical trauma: Accidental cheek bites, use of orthodontic appliances or ill-fitting dental prostheses.

  • Stress and fatigue: Emotional and physical stress can trigger the appearance of sores in the mouth.

  • Nutritional deficiencies: The lack of vitamins and minerals such as vitamin B12, zinc, folic acid and iron can contribute to the formation of sores in the mouth.

  • Food allergies: Certain foods, such as nuts, citrus fruits, chocolate and cheese, can trigger mouth sores in some people.

  • Immune disorders: People with a weakened immune system are more susceptible to developing canker sores.

  • Hormonal fluctuations: Hormonal changes, especially in women, can be a triggering factor.

  • Genetic predisposition: If family members suffer from mouth sores, there is a greater chance that you will too.


Symptoms of canker sores (mouth sores)

Common symptoms of canker sores include:

  • Pain and discomfort: They can be intense and make eating and speaking difficult.

  • Small, round lesions: With red edges and a white-yellowish center.

  • Burning sensation: Sometimes, before the actual appearance of ulcer.

  • Inflammation of the lymph nodes: In more severe cases, the lymph nodes in the neck area may be affected.


Types of canker sores (mouth sores)

There are several types of canker sores, which differ in size, shape and severity:

  • Minor canker sores: The most common, usually less than 1 cm in diameter, round or oval, heal in 7-14 days without leaving scars.

  • Large canker sores: Less common, larger than 1 cm, with irregular edges, can last weeks or months and leave scars.

  • Herpetiform canker sores: Rare, very small (1-2 mm), appear in large groups and heal in 7-14 days without leaving scars.

  • Recurrent chronic canker sores: Canker sores that recur frequently, significantly affecting quality of life, and can include any type of canker sore.


Treatment of canker sores (mouth sores)

At SDS Dental Clinic, we offer a wide range of treatment options for canker sores, but we take particular pride in our use of laser technology, ideal for those looking for a "quick treatment for canker sores". This modern treatment offers numerous benefits and is preferred by many patients for its effectiveness and convenience.

What is laser treatment?

Biolase's Epic X laser treatment for mouth sores involves the use of a low-intensity laser to reduce the pain and inflammation associated with the lesions. The laser is directed to the affected area, which helps to speed up healing and reduce discomfort, thus providing a quick treatment for canker sores.

How it works?

The laser emits a concentrated light that is absorbed by the affected tissues, resulting in:

  • Local disinfection: The laser destroys bacteria and other microorganisms in the area.

  • Reduction of inflammation: Laser energy reduces swelling and inflammation.

  • Stimulation of tissue regeneration: Increases the speed of tissue healing.

  • Pain Relief: Soothes pain immediately, providing quick comfort.

How is the procedure done?

The procedure is simple and painless. During the treatment, the patient sits comfortably, and the dentist uses a laser device to directly treat the affected area. The length of the procedure varies depending on the size and number of lesions, but generally takes no more than a few minutes. In addition, it does not require anesthesia as the laser does not cause pain, making this treatment ideal for those looking for a quick treatment for mouth sores.

In addition to laser treatment, there are other effective methods of managing and treating canker sores:

  • Topical medications: Local anesthetics and corticosteroids to reduce pain and inflammation.

  • Oral medications: Analgesics and oral corticosteroids for severe cases.

  • Antiseptic rinses: Products with chlorhexidine or oral rinses with steroids to prevent infections.

  • Home remedies: Rinse with salt water, soft foods, baking soda.

  • Food supplements: Vitamins and minerals, such as B12, B6, folic acid, zinc and iron.

  • Antibiotics: For secondary bacterial infections.

  • Natural treatments: Plant extracts (aloe vera, chamomile) and probiotics.

  • Mouthguards: Application of patches on sores in the mouth for protection and relief.


Prevention of canker sores (mouth sores)

  • Maintain good oral hygiene: Brush your teeth twice a day and floss daily to prevent the build-up of bacteria.

  • Avoid trigger foods: Identify and avoid foods that trigger canker sores.
