What are Crowns?
Crowns are tooth-shaped caps which fit over the top of your teeth.
Why are Crowns used?
Teeth with large fillings (and/or root fillings) are weak, and can break when you bite. They can have hidden cracks which make them tender to bite on or sensitive to hot or cold. A crown will protect a heavily filled tooth. Crowns can also be used cosmetically to improve the appearance of your teeth. Your Hamilton Dentist can tell you which of your teeth would best be protected by crowns before other problems develop.
What are Crowns made of?
Usually porcelain, because the colour can be matched to your existing teeth. The porcelain ‘tooth’ may have a gold or other metal core for strength. If a natural appearance is not essential (for example, at the back of your mouth), a gold or other metal crown may be used.
How are crowns fitted?
Hamilton Dental reduces the size of the existing filling and tooth to make room for the new crown. Then we take a mould which is either made up on site using our CEREC equipment and the crown is ready the same day. Or for very technical cases the mould is sent to a dental technician. Sometimes the filling in the tooth to be crowned is completely removed to check for decay and to rebuild the tooth for increased strength. Your Hamilton dentist will fit a temporary crown to cover your tooth until the permanent crown is ready if we have to use the dental technician. Once the permanent crown is ready, we check the fit and appearance before cementing it in place.
Crowns provide strong, attractive, long term protection for your mouth.
