Dental Crowns (cont.)

What Are "Onlays" and "3/4 Crowns"?

These are variations on the technique of dental crowns. The difference between these crowns and the crowns discussed previously is their coverage of the underlying tooth. The "traditional" crown covers the entire tooth; onlays and 3/4 crowns cover the underlying tooth to a lesser extent.

How Long Do Dental Crowns Last?

On average, dental crowns last between 5 and 15 years. The life span of a crown depends on the amount of "wear and tear" the crown is exposed to, how well you follow good oral hygiene practices, and your personal mouth-related habits (you should avoid such habits as grinding or clenching your teeth, chewing ice, biting your fingernails and using your teeth to open packaging).

Does a Crowned Tooth Require Any Special Care?

While a crowned tooth does not require any special care, remember that simply because a tooth is crowned does not mean the underlying tooth is protected from decay or gum disease. Therefore, continue to follow good oral hygiene practices, including brushing your teeth at least twice a day and flossing once a day-especially around the crown area where the gum meets the tooth.

How Much Do Crowns Cost?

Costs vary depending on what part of the country you live in and on the type of crown selected (for example, porcelain crowns are typically more expensive than gold crowns, which are typically more expensive than porcelain-fused-to-metal crowns). Generally, crowns can range in cost from $500 to $900 or more per crown. A portion of the cost of crowns is generally covered by insurance. To be certain, check with your dental insurance company.
