Dental crowns are restorations that protect damaged, cracked or broken down teeth. A crown strengthens your existing, damaged tooth so as to preserve its functionality.
Why might you need crowns?
If your tooth has undergone significant decay and there is not enough tooth structure remaining to support a filling or an inlay and maintain functionaility.
If a large portion of your tooth has fractured and it cannot be built up using traditional composite bonding techniques.
If you have a large cavity and opt for the additional protection a crown offers to your tooth over a large composite filling or an inlay.
If you have had a dental implant to replace a missing tooth, a crown will be fitted to the abutment of the titanium implant.
Following root canal treatment, a crown is often needed to strengthen the tooth.
If you grind your teeth and have a poor diet, acid errosion may reduce your teeth to a point where the only option available is to crown them.
What materials can crowns be made from?
In modern-day dentistry there is a wide variety of dental materials to choose from. Some crowns are made from full gold, where as others are made from an alloy of metals fused to a porcelain outer shell. After time, crowns that are made from a combination of metal fused to porcelain can begin to show dark gum lines that are not aesthetically attractive. All-porcelain or – ceramic crowns are the best choice for a natural cosmetic look. There are many different brands and types of porcelain crowns, and the variation between the costs of dental crowns at different dental practices may well reflect the quality of the materials used.
How long do crowns last?
This will depend largely on how well you look after your teeth. Dental crowns require the same level of care and attention as your natural teeth. Provided you have a good oral hygiene program, attend regular checkups at your dentist, don’t grind your teeth, maintain a tooth-kind diet and don’t do things like open beer bottles with your teeth, a high-quality dental crown can last 10-15 years.
