Dental Fillings
What are Dental Fillings?
Tooth fillings restore a tooth damaged by decay, a chip, or a crack by removing the compromised part and rebuilding it so it looks and functions like natural enamel again.
Left untreated, a small cavity can turn into a bigger problem deeper decay, a cracked tooth, or worse, a dental emergency. If you're dealing with sudden tooth pain, see our Emergency Dentist page for same-day options.


The Tooth Filling Process
Removal of Caries and Decay
Your dentist numbs the area, then carefully removes the decayed portion of the tooth using a dental drill or, for smaller cavities, minimally invasive tools, leaving as much healthy tooth structure in place as possible.
Application of Appropriate Filling Material
The right material depends on the cavity's size and location, your bite, and your budget. See the Types of Dental Fillings tab below for a full breakdown of composite, ceramic, gold and glass ionomer options.
Filling the Hole or Damage
The material is shaped and set in layers so the filling matches your natural bite. Your dentist checks the fit before you leave so the tooth feels normal when chewing.
Types of Dental Fillings
Composite Fillings
Composite fillings, made of a blend of plastic and fine glass particles, are an excellent choice for those concerned about aesthetics. They can be color-matched to your natural teeth, making them nearly invisible.
Ceramic Fillings
Ceramic fillings, also known as porcelain fillings, provide excellent aesthetics and durability. They are highly resistant to staining and are a preferred choice for visible teeth.
Gold Fillings
Gold fillings, while less common due to their cost, offer remarkable durability. They are often chosen for their longevity, but their yellow color may not appeal to everyone.
Glass Ionomer Fillings
Glass ionomer fillings are a unique option that releases fluoride, making them ideal for patients with a high risk of tooth decay. They are commonly used for children's teeth and as a temporary filling material.
