A canker sore is a painful, open sore in the mouth. Canker sores are white or yellow and surrounded by a bright red area. The first symptom is usually a tingling or burning sensation that you feel before other symptoms develop.
Pain decreases in 7 to 10 days, with complete healing in 1 to 3 weeks. Particularly large ulcers (greater than 1 cm in diameter) often take longer to heal (2 to 4 weeks). Occasionally, a severe occurrence may be accompanied by nonspecific symptoms of illness, such as fever. Canker sores often return.
Canker sores can be triggered by emotional stress, dietary deficiencies (especially iron, folic acid, or vitamin B-12), menstrual periods, hormonal changes, food allergies, and similar situations. They occur most commonly with viral infections. In some cases, the cause can not be identified.
Dr. Doolin and Dr. Haddad are specially trained to use a dental laser to treat canker sores, resulting in decreased symptoms and shortened duration of the canker sore.
Applying alum can also be effective on how to get rid of canker sores. Make sure you are prepared for the unpleasant taste in your mouth when you do this remedy. Apply a pinch of alum over the lesion of your canker sore. Then, rinse with water after 30 seconds.
