Tooth Fillings
In our practice 99% of the time we use composite resins (tooth colored materials) to restore damaged teeth. However, many people still have silver/mercury fillings in their mouths from years past. These fillings are not particularly pleasing to the eye, and we know that by unavoidable design, silver/mercury fillings ultimately result in a weaker tooth structure. Porcelain onlays and resin onlays create fillings that are not only beautiful (or unnoticeable) but also add strength to weakened teeth thanks to designs and new bonding technologies.
Disadvantages of Silver fillings
Silver fillings have many drawbacks. The edges of the silver filling can wear down, become weak or break. This results in the tooth not being protected and allows cavities to get started once again. With age, the metal of a silver filling expands, contracts, and can fracture the tooth. They can corrode, leak and cause stains in your teeth and on your gums.
Fortunately, silver fillings can safely be replaced with Tooth-Colored Restorations.
Advantages of Tooth-Colored Restorations
There are many advantages to tooth-colored restorations. Resin onlays are bonded to the teeth creating a tight, superior fit to the natural tooth. Such restorations can be used in instances where much of the tooth structure has been lost. The tooth remains intact and stronger. The adhesive used to bond the resin also seals the dentin and patients have decreased sensitivity to cold, and patients can chew right away after the procedure is complete.
The result is a beautiful smile!
Replacing silver fillings with a tooth colored restoration ( onlays, crowns, and veneers) requires two appointments:
Your First Appointment:
- The old filling is removed along with any additional decay.
- An impression is made of your teeth. A model of your teeth is made and sent to the lab.
- A temporary onlay, crown, or veneer is placed on the tooth.
At the Lab:
A resin is molded to fit the tooth and look natural.
Your Second Appointment:
- The temporary restoration is removed.
- A conditioning gel is placed on your tooth to clean the tooth surface and prepare it for the new restoration.
- Bonding cement is placed on the tooth and a high intensity light bonds the resin to the tooth.
- The tooth is then polished.
Your teeth are restored to a natural look and feel, they are stronger and the tooth is protected!
