How Teeth Are Restored
After diagnosing the problem and devising a treatment plan, the next step to restore a tooth to health is to make you comfortable. We will give you a local anesthetic so that you do not feel any discomfort. After the decay is removed, the tooth is ready to receive either a direct restoration or an indirect restoration.
A direct restoration means that the tooth can likely be restored in one visit and that there is sufficient tooth structure for the filling to go inside of the tooth. Examples of direct restorations are amalgam, which is silver-colored; and composite, which is tooth-colored. There have been more amalgam fillings placed worldwide than any other kind of filling, but tooth-colored fillings are being placed more frequently in recent years because they match the remaining teeth and look like the natural tooth.
An indirect filling means that the restoration is made outside of your mouth, either by a lab or by a milling machine. An indirect filling also needs to be cemented into place. Examples of indirect restorations are crowns, inlays, and onlays. A crown covers the entire tooth, an inlay fits inside the tooth and can replace a wall of the tooth, and an onlay replaces at least one cusp of the tooth.
Most indirect restorations take two or more appointments to complete, with the exception of restorations that are milled by a machine in the office. Cast gold is the most durable indirect restoration material, but porcelain ceramics are gaining in popularity because of their superior esthetic qualities.
Please see our Fillings Gallery, below, to view the types of results we can achieve with these various materials.
You will need at least two visits for a gold restoration. During the first visit, any decay or old filling material is removed, the tooth is prepared to accept a gold restoration, an impression is taken, and a temporary filling is placed.
The impression is then sent to the lab and a stone cast is made, which enables the lab to work on your tooth without your presence. The lab makes a wax pattern, which is then cast into a gold restoration. When you return for your second appointment, the gold restoration is cemented into place.
- Good resistance to further decay
- Wears well as – almost the same hardness as enamel
- Does not fracture under stress
- Good longevity
- Conducts hot and cold
- Multiple visits
Porcelain is the most natural looking of the choices we have to restore teeth. It is used either by itself in veneers, inlays, onlays, and crowns, as well as combined with metal for crowns. Porcelain restorations require two visits or they can be milled in the office with a milling machine. After the porcelain is cemented to your tooth, it is very difficult to notice that the tooth had any treatment at all.
- Resistance to surface wear
- Long lasting
- Wears well as it holds up to chewing force
- Brittle material can fracture
- Usually requires more than one visit
