Tooth Fillings

Introduction

Tooth fillings are substances used to restore teeth following tooth decay or injury.  They prolong the life of your natural teeth.  Fillings fill in openings on a tooth after a cavity is removed or a crack has occurred.  Fillings are made of various materials and have different strengths.  Advances in dentistry have made fillings less obvious than ever before.  Your dentist will help you select the most appropriate option for you.

The most common types of fillings are conventional amalgams, composite resin fillings, and ionomers.  Conventional amalgams are composed of more traditional dental materials including gold, silver, metals, and small amounts of harmless mercury.  Conventional amalgams are very strong and durable.  They are used to fill large spaces.  They are practical for back teeth because the filling can withstand strong chewing forces.  Conventional amalgams can darken over time.  They may be noticeable when you talk or laugh.

Composite resin fillings are also referred to as “composites” or “filled resins.”  They are made of resins and glass or quartz.  They are used to restore small to mid-size spaces.  They are best for places with moderate chewing forces.  Composite resin fillings are made to match the color of your teeth.  They are barely noticeable.

Ionomers are fillings composed of acrylic acids and fine glass powder or acrylic acids, acrylic resins, and glass fillers.  Ionomers are used to fill in small areas on the roots of teeth or in between teeth.  They do not tolerate chewing pressure well.  They are well suited for people at risk for tooth decay because ionomers release flouride which help prevent tooth decay.  Ionomers are made to match the color of your teeth.
