What will the dentist do to fix a cavity and will it hurt?

Answer by  amber33 (1941)

The dentist will numb the gums and the area surrounding the tooth so you will not feel anything. He will use a little drill like instrument to clean out the cavity and put some materials in the tooth to fill the tooth back up to where it was before.

Depending on how big the cavity is, the may or may not have to anesthetize the area. If it is a large cavity they will give you a shot to numb the area. Than they will drill out the cavity and fill it.

The dentist will usually numb the area so that you won't feel much pain during the placement of a filling. Your dentist will then drill away the decayed portion of tooth, then fill it with a cement-type filling. After drying it quickly, the dentist sands it down.

They will have to drill it out to fill the cavity, but don't worry, it will not hurt. The dentist will either give you a shot in the back of the jaw (on the inside) or sedate you with a pill.
