Dental Dam

My dentist always uses something called a Dental Dam when he does root canals and fillings. I don’t like how it feels. Can you tell me what its used for?

Anne,

Sure. A dental dam, also called rubber dam, are designed to keep your tooth dry for procedures like root canals and sometimes composite fillings. The purpose for it is to protect your tooth from saliva. Our saliva has bacteria in it that can increase the chance of your tooth getting reinfected after your root canal procedure. It is also useful for keeping your tongue out of the way as well as keeping dental material and water out of your throat during the procedure. This helps people with a strong gag reflex.

Some dentists will use it when doing white (composite fillings) also because if the tooth doesn’t stay dry, the material won’t bond properly to your tooth. I would discuss with your dentist how you feel about the dam and see if you can work out a mutually beneficial solution.
