A cavity (caused by a disease named caries) happens when bacteria in the mouth produce acids that attack your teeth. With time , this acid can dissolve away the enamel on your teeth and cause a hole known as a cavity . Without treatment by your dentist , dental decay may continue to advance . If you need to have a tooth restored (filled), your options may include several different materials. Your dentist will discuss with you which material is best for your case.In our clinic we use the “tooth colored” restoration fillings. They include composite resin , glass ionomer and porcelain materials which are aesthetic fillings.
Dental fillings fall into two categories : direct restorations and indirect restorations.
Direct restorations are filling placed immediately into a prepared cavity in a single visit. The dentist prepares the tooth , places the filling and adjusts it during one appointment.
Advantages of the composite resin :
- Color can be matched to the existing tooth;
- Composite is a relatively strong material , providing good durability;
- Composite may generally be used on either front or back teeth;
- Does not corrode;
- Holds up well to biting forces;
- Moderately resistant to further decay , new decay is easy to find;
- Can be repaired easily.
Indirect restorations may require two or more visits. They include inlays , onlays and composite veneers. During the first visit , the dentist prepares the tooth and makes an impression . This impression is sent to a dental laboratory , which creates the dental restoration (filling). At the next appointment , the dentist cements the restoration to the prepared tooth and adjusts it.
