How Long Does It Take To Fill A Small Cavity. It takes a while for a cavity to form, sometimes even years. Can small cavities go away?
As bacterial acid in the mouth dissolves the enamel surface of the tooth it causes a growing opening which is called a cavity. With that being said, i will give it to you straight. A simple filling may take as little as 20 minutes.
How fast this opening enlarges and travels a few millimeters depends on the amount of acid present, how intact the tooth has become as it has grown to adult size, how many surface defects there are, and how many scars, abrasions or fractures are in the surface enamel or.
It depends on the size of the restorations and what type. Some times very small cavities are very sensitive, and some very large cavities are not at all. Plan to spend about an hour getting your filling to be on the safe side. The time factor from cavity to root canal depends on the environment in the mouth.
