Crowns

All treatments available in every 'Instore Dental' practice.

Q: What is a 'crown'?

A: A crown is like a special sleeve made of metal or porcelain (or both) that goes over a damaged or weak tooth. Your dentist will match it up to the shape and, in the case of porcelain crowns, colour, of your other teeth so that it will look natural.

Q: How long will a crown typically last?

A: A crown will usually remain in good condition for many years, although it is important to remember that this is very often dependent on the health of the tooth underneath as well as the quality of the care the tooth and crown are given on a day-to-day basis.

Q: How do you make sure the crown is the correct size for my tooth/teeth?

A: The dentist will shape the tooth so that, with the artificial crown, it will be the same size as a normal tooth. Preparation time will depend on how damaged the tooth is and whether it needs to be built up with a filling first. The tooth might have to be root-filled first - this is sometimes called 'removing the nerve'. The crown is sometimes held in place by a peg in the root canal if a large amount of the tooth is missing.

Q: How is a crown fitted?

A: Your dentist will use a soft mouldable material to make an exact 'impression' of the tooth that is to be crowned and also of the nearby teeth. A dental technician uses the impressions to make the crown the exact height and size needed. A thin cord may be used to hold the gum away from the tooth so that the impression is accurate around the edges.

A temporary crown made of plastic or metal is put over the tooth until the permanent crown is made. You can chew on a temporary crown but it won't be as strong as the finished one. When the crown is fitted, your dentist will make small adjustments to make sure you can bite comfortably. The crown is tried on first, and then glued into place.
