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) create fillings that are not only beautiful (or unnoticeable) but also add strength to weakened teeth. These restorations are esthetically pleasing and very strong thanks to 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 lets cavities get started once again. With age, the metal of a silver filling expands, contracts, and can split.
Silver fillings contain 50 percent mercury. They can corrode, leak and cause stains on your teeth and gums.
Fortunately, silver fillings can safely be replaced with Tooth-Colored Restorations (onlays).
Advantages of Onlays
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.
Since the resin used in tooth-colored restorations contain fluoride this can help prevent decay. The resin wears like natural teeth and does not require placement at the gum line, which is healthier for your gums!
Silver Fillings Can Be Replaced With Onlays in One Day
- 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 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.
Home Care Instructions
When an anesthetic has been used, your lips and tongue may be numb for several hours after the appointment. Avoid any chewing and hot beverages until the numbness has completely worn off. It is very easy to bite or burn your tongue or lip while you are numb.
It is normal to experience some hot, cold & pressure sensitivity after your dental filling appointment. Injection sites may also be sore. Ibuprofen (Motrin), Tylenol or aspirin (one tablet every 3-4 hours as needed for pain) work well to alleviate the tenderness. If pressure sensitivity persists beyond a few days or if the sensitivity to hot or cold increases, contact our office at (303) 457-3046.
You may chew with your composite fillings as soon as the anesthetic completely wears off, since they are fully set when you leave the office.
If your bite feels uneven, if you have persistent pain, or if you have any other questions or concerns, please call our office at (303) 457-3046.
