What do you suggest if i have a very bad canker sore?

Zilactin: Zilactin is my favorite. A topical ointment your can buy at your pharmacy. It sometimes stings a little at first but it cleans the wound and it very soon stops hurting and heals quickly. Some dentist have a stronger solution of a similar product on hand in their office. Works the same way. Little more sting, quicker results. If the sore persists more than two weeks you need to see a dentist asap.

Canker sores : Canker sores are the most common oral lesions. Individual ulcers typically last 1-2 weeks. The condition is idiopathic (cause is not known) recurrent aphthous ulcers is usually self-limiting. If concerned see your dentist after 10 days or visit today for laser immediate amelioration.

Canker sore: A canker sore typically lasts 10 days. Avoid hot, spicy, acidic foods and drinks. Using an OTC product will help you feel better while it heals. If it does not heal or if you get frequent canker sores see a dentist for an evaluation
