Dr. Gary Sandler answered

Specializes in Dentistry

Mouth sores: Canker sores also called aphthous ulcers usually take 7-10 days to heal completely. Other sores can take less or more. Any sore or lesion lasting longer than 2 weeks should be seen to confirm diagnosis and make sure it's not something serious that requires treatment.
