Crowns and Bridge
Dental crowns are caps placed on top of damaged teeth. Crowns are used to protect, cover and restore the shape of your teeth when fillings don’t solve the issue. Dental crowns can be made out of metals, porcelain, resin and ceramics. They typically don’t require special care over time other than regular good oral hygiene.
Over time, your teeth can get damaged. This can happen for a variety of reasons, like tooth decay, injuries or general wear. Dental crowns are tooth-shaped “caps” that are placed over your tooth to restore its shape, size, strength and appearance.
When are dental crowns needed?
Dental crowns are one of the most common restorations performed by dentists. There are several reasons you may need a crown, including:
- Covering a broken or decayed tooth with little tooth structure left.
- When a tooth is cracked.
- After receiving root canal treatment to provide strength.
- After receiving a dental implant.
- Cover misshapen or worn teeth.
- Protect teeth at high risk of decay.
If you have missing teeth, your dentist can close (or bridge) the gaps in your smile with dental bridges. A bridge is similar to a crown, only is it anchored to the healthy teeth on either side of the gap to ensure strength and stability, a false tooth is then attached to the anchored abutments. A bridge can be created to replace multiple teeth and provides a realistic result as it is created with the same materials as a crown.
What is the process for a dental bridge?
Like crowns, the process for a bridge consists of two appointments. During the first visit the abutment teeth are prepared. Preparation involves removing a portion of enamel to allow room for a crown to be placed over them. Next, a 3D scan of the teeth will be taken, this provides the lab a model from which the bridge and crowns will be made. Your dentist will make temporary crowns for the abutment teeth, to protect the exposed teeth and gums while the bridge is being made.
During the second visit, your temporary crowns will be removed and the new porcelain or metal bridge will be checked and adjusted, as necessary, to achieve a proper fit. Once the ideal bite and fit is achieved, your dentist will cement it permanently in place.
Dental bridges are a lasting solution for missing teeth, at King Street Dental we provide 3 main options:
A bridge is made up of two or more crowns for the teeth on either side of the gap. These two or more anchoring teeth are called abutment teeth, and have a false tooth/teeth in between. These false teeth are called pontics and can be made from gold, alloys, porcelain, or a combination of these materials. Dental bridges are supported by natural teeth or implants.
Similar to a traditional bridge, Maryland dental bridges employ two natural abutment teeth, one on each side of the gap. However, while a traditional bridge uses dental crowns on the abutment teeth, a Maryland bridge uses a framework of either metal or porcelain that is bonded onto the backs of the abutment teeth. Like a traditional bridge, a Maryland bridge can only be used when you have a natural tooth on each side of the gap.
Implant Supported Bridge
Implant-supported bridges are very similar to traditional bridges. However, instead of being supported by dental crowns placed over adjacent teeth, implant-supported bridges attach to small titanium posts embedded in the jaw. The number of posts placed will depend on the size of the bridge.
This is considered the strongest and most stable system.
Frequently Asked Questions
How long do crowns and bridges last?
With good oral hygiene and regular check ups from your dentist, crowns and bridges can last between 10 and 30 years when well cared for.
Does a crowned tooth require special care?
While a crowned tooth does not require special care, the underlying tooth is still susceptible to decay or gum disease. Therefore, continue to follow good oral hygiene practices to ensure decay does not form under the crown.
Will the crown/bridge match my teeth?
Yes! The colour of the crown/bridge will be the same as your surrounding teeth. Unless requested for gold/metal alloy.
What if the crown/bridge falls out?
If your crown/bridge falls out it is important to keep the restoration and bring it to your dentist for reinserting.
