The exact cause of canker sores is unknown. Although the cause it unclear, researchers suspect that a combination of factors is the most likely explanation. It is thought that certain foods—including citrus or acidic fruits or vegetables, can cause or make canker sores worse. Likewise, canker sores can be caused by stress, allergic reactions to certain bacteria in your mouth, or other kinds of tissue damage, such as a cut from a sharp tooth or braces. Even brushing too vigorously may cause a canker sore. Canker sores might also be the result of certain conditions such as celiac disease, inflammatory bowel diseases, or other autoimmune disorders. In any case, canker sores can be extremely painful, making it difficult to eat or even speak.
Laser treatment offers an alternative to ointments, mouth rinses, or other such treatments. These can sometimes have unpleasant side effects and often only treat the symptoms. Ointments have to be applied numerous times throughout the day and, according to the Mayo Clinic, mouth rinses containing the antibiotic tetracycline can make you susceptible to oral thrush, a fungal infection that causes mouth sores. Tetracycline can permanently discolor children’s teeth, besides. Antiviral medications sometimes have side effects that prevent their use for certain patients with varying medical circumstances. Laser treatment is the most effective means for treating canker sores. Laser treatment gives immediate pain relief and helps the sore heal much faster. Not only is it effective, it’s fast too. Most procedures take about 15 minutes and it’s relatively inexpensive. In fact, most dental insurance will cover the procedure.
Small or minor canker sores will heal in a few days and might not require any kind of treatment, but if you have a particularly painful or large sore, you should see a dentist for treatment. If you experience canker sores regularly or have many at one time, seeing a dentist to discuss your condition is the best way to get relief from a painful condition and to make sure the sores are not part of a more serious, underlying condition.
