Fillings & Bonding

If you suffer tooth decay, we can treat this with fillings, inlays or onlays, or in more extreme cases, with crowns.

There are several methods of dealing with cavities caused by decay. For smaller cavities, the dentist can use filling material such as an amalgam or an inlay of porcelain, gold, or hardened composite.

Fillings are the most economic choice, and can be made from silver amalgams or white composite resin. Amalgams last about 20% longer than the more natural-looking composites. There are other factors to consider such as the location of the tooth, about which the dentist will advise you.

Inlays are an alternative to fillings when the cavity is less than a third the width of the tooth. They are usually made of porcelain, sometimes gold. An inlay is produced to order, so it involves more than one visit. It fits precisely into the tooth where it is then bonded into place. For large cavities, inlays are often the best solution. These are usually either gold or porcelain, and have the same benefits as an inlay as well, lasting up to 30 years.

When none of these methods are possible because the cavity is too severe, a crown is used to cap or enclose the tooth. The process involves making an impression of the tooth from which to fabricate the crown, which is then fitted at a later visit. Crowns are made from stainless steel (mostly for children's primary teeth), and from gold and other metals. Ceramics, porcelain, special resins and other combinations can also be used depending on the location and nature of the need.
