Steps of Dental Filling

Local anesthesia – at the beginning of your filling procedure, you may be given local anesthesia to numb the area around the tooth.

Tooth decay removal – then the dentist will cut through the enamel using a drill to remove any decay. After the dentist removes the decay, the dentist will shape the space to ready it for the dental filling.

Etching – for a bonded filling the dentist will etch the tooth with an acid gel before placing the dental filling.

Resin application – for certain types of dental fillings the dentist will layer on the resin and harden it using a bright light. This makes it strong.

Polishing – after the filling has been placed, your dentist will polish the tooth.


How Do I Know if I Need a Filling?

Only a dentist can detect whether you have a cavity that needs to be filled. During a checkup, the dentist will use a small mirror to examine the surfaces of each tooth. Anything that looks abnormal will then be closely checked with special instruments. We may also X-ray your entire mouth or a section of it. The type of treatment your dentist chooses will depend on the extent of damage caused by decay.


What Is Dental Filling?

A dental filling is a way to restore a tooth damaged by decay back to its normal function and shape. When a dentist gives you a dental filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out cavity with a filling material.

By closing off spaces where bacteria can enter, a dental filling also helps prevent further decay. Materials used for dental fillings include porcelain, a composite resin (tooth-colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).
