A dental or tooth filling is a repair process used by a dentist to fix a hole or cavity in the tooth back to health. The tooth needs to be cleaned and the decay and bacteria removed using a dental drill. This is driven by air, so makes a high pitched sound. The dentist will then use a filling to repair and fill in the hole.
The filling protects the tooth from further decay, helps with chewing, and restores your smile and confidence. A tooth filling is also used to restore broken and worn-down teeth, which can occur due to trauma or grinding.
