What Are Tooth Fillings and Why Are They Needed?
Tooth fillings are a restorative dental procedure used to treat teeth affected by decay, fractures, or wear. By removing the damaged portion of the tooth and filling it with a suitable material, the dentist restores both function and appearance. Fillings prevent further decay, protect tooth structure, and eliminate pain or sensitivity caused by cavities.
