hi,doctor
Hi Thanks for The Questions you mentioned you are 63 years old and all your teeth are fine...... but still you are having ulcers frequently in oral cavity and your dentist suggested you to go for extraction which you don't want..... At this age usually teeth gets attracted and develops sharp edges which are the common reason for ulcers so instead of extraction just tell your dentist to reduce those sharp edges or reshape your teeth.it will heptane you
