We are a mercury-free practice. 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 inlays and Tooth Colored Restorations (onlays) and composite materials create fillings that are not only beautiful but also add strength to weakened teeth. These restorations are aesthetically pleasing and very strong thanks to new bonding technologies. And only one appointment is needed.
Disadvantages of Silver fillings
Silver fillings are safe according to the Canadian Dental Association yet have some drawbacks. The edges of the silver filling can wear down, become weak or break causing an open space between the tooth and the metal. This results in the tooth not being protected and lets cavities get started once again.
1. Silver fillings look like blackened spots on your teeth and are highly noticeable when you speak and smile.
2. Silver fillings contain 50 percent mercury. They can corrode, leak and cause stains on your teeth and gums.
3. Fortunately silver fillings can be easily replaced with naturally looking tooth-coloured restorations.
Advantages of Tooth-Coloured Onlay Restorations
There are many advantages to tooth-coloured onlay restorations. Composite fillings are bonded to the natural tooth creating a tight, superior fit . Such restorations can be used in instances where much of the tooth structure has been lost.
Since the bonding resin used in onlay restorations bonds physically and chemically to the tooth this can help prevent fracture as well as decay. The composite filling wears in a similar pattern to your natural teeth therefore is gentle on opposing teeth when chewing
The final result is a natural and beautiful smile!
Replacing Silver Fillings with a Tooth Coloured Restoration
You can have your silver fillings replaced with tooth-coloured restorations (inlays/onlays). This process 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 is placed on the tooth.
At the Lab: A composite resin is carefully placed into the model of your teeth. It is then designed to look natural.
Your Second Appointment:
- The temporary onlay is removed.
- A conditioning gel is placed on your tooth to prepare it for the new onlay.
- 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 their original look and feel, they are also stronger and the tooth is protected!
