Canker sores are small, painful ulcers that can develop in the mouth. They are caused by a variety of factors, including stress, hormonal changes, and certain foods. Canker sores typically heal on their own within a few weeks, but they can be very uncomfortable in the meantime.
Dentists can remove canker sores using a variety of methods, including laser therapy, cauterization, and prescription medications. Laser therapy is a quick and painless procedure that uses a laser to vaporize the canker sore. Cauterization is a more invasive procedure that involves burning the canker sore with a heated instrument. Prescription medications can also be used to reduce the pain and inflammation associated with canker sores.
