It is perfectly normal for your dentures to lose their shape over time. The contour of your gums can change, and your dentures can be damaged or broken if you drop them during cleaning or even by eating hard or tough foods. While it might seem like a good idea to repair them yourself, you should leave that to our dentist. At Montgomery Street Dental, we offer denture relines, rebasing and repairs in San Francisco, California, and you can call 415-398-6344 for a visit with Dr. Alireza Khoshvaghti.
