Following are the steps involved in filling your teeth:
First of all, the dentist will apply local anesthesia to numb the area around your affected tooth.
Next, the dentist will remove the decayed area with the help of a suitable instrument. It can either be a drill, laser instrument, or air abrasion instrument.
After double-checking that all the decay and debris are removed, the dentist will clean the area.
The dentist will do the filling and will polish it to give it a finish.
A glass ionomer liner will be put in to protect the nerves for the filling near the root.
In case of a tooth-colored filling, the dentist also needs to use a special light to harden it. And it will be applied in layers for a better finish.
