Cavity Filling Types That Are Available in North York

If your dentist finds decay or cavity in one of your teeth, you will need a cavity filling in a North York dental clinic. This involves removing the decayed part of the tooth and filling the space that is left. You have several choices for material, each of which has its own share of advantages and disadvantages.

Types Of Cavity Filling:

1. Cast Gold

One of the most durable materials available, cast gold fillings tend to last 15 years or more and there is no risk of corrosion. Their strength also allows you to chew your food without damaging your teeth.

However, these benefits come at a price — gold cast filings are one of the most expensive options. Another downside is that cast gold fillings require two trips to the dentist for the fitting.

2. Silver

Another long-lasting option, silver (also called amalgam) fillings are a more cost-effective option. Plus, like cast gold, they stay strong under the pressures of chewing.

Unfortunately, to fit amalgam fillings, your dentist may need to remove some of the healthy part of your tooth. Furthermore, there is a chance of damage to your teeth, including cracks when teeth are exposed to hot or cold and discolouration.

3. Composites

Another cavity filling type is Composite filling. This is an aesthetically-pleasing option, made in the same shade as your teeth. The material bonds with your teeth, improving tooth structure, and the fillings require less of the tooth be removed than silver fillings.

Something to bear in mind is that composite fillings can cost twice as much as amalgam fillings and may only last half as long. They also take around 20 minutes longer to fit.

4. Ceramics

Made from porcelain, ceramic fillings also match your teeth colour, but they are less likely to stain than composite fillings. They also last much longer — usually around 15 years. The main disadvantages are that they are more abrasive than composite fillings and they cost around the same as cast gold.
