Restorative dentistry with porcelain restorations
Teeth may be damaged through decay or trauma, and can be repaired with restorative dentistry which prevents further decay and infection, while conserving tooth structure.
After diagnosing an issue and creating a treatment plan, the first step to restore a tooth to health is to ensure that you are comfortable. We will place some topical gel on the gum before we give you some local anaesthetic 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 enough 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 coloured . Amalgams are not placed in our practice.
Composite resins are an approach to repairing broken teeth and cavities caused by tooth decay to look natural, match to the remaining teeth and restore health. Resin can be a good filling material when there is enough tooth structure to support it, but may wear out after about 5 years, and is technique sensitive. Our practice uses SonicFill 2 technology to restore the molar and premolar teeth.
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 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 appointments to complete. Cast gold is the most durable indirect restoration material, however porcelain ceramics are primarily requested and recommended because of their excellent aesthetics and they are still very strong.
Porcelain is the most natural looking option to restore teeth, and is much stronger than composite resin fillings. It is the strongest way to repair a damaged tooth with high aesthetic demands, and has been used for many years in veneers, inlays, onlays, and crowns. Porcelain restorations require two visits,and once it is completed, it is usually undetectable.
- Matched to other teeth
- Resistant to surface wear
- Long lasting
- Holds up well against chewing forces
- Brittle material may fracture with very heavy forces
- Requires two appointments
Gold restorations are a mixture of gold and other metals, to make them stronger.
You will need two appointments for a gold restoration. During the first visit, any decay or old filling material is removed, the tooth is prepared for the gold restoration, an impression is taken, and a temporary filling is placed.
The impression is then sent to the lab and a stone model is made, from which the lab makes a wax pattern, which is then cast into a gold restoration, within two weeks. When you return for your second appointment, the gold restoration is cemented into place.
- Good resistance to further decay
- Wears well because it has a similar hardness to enamel
- Is unbreakable
- Highly durable
- Conducts temperature
- Gold colour is undesirable for many patients
- Two appointments
