Crown

A crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth using a dental cement. Crowns can be made from many materials, which are usually fabricated using indirect methods. Crowns are often used to improve the strength or appearance of teeth. While unarguably beneficial to dental health, the procedure and materials can be relatively expensive.

Why get a crown?
A crown is used to strengthen a weakened tooth, such as a tooth which has had root canal therapy, a large restoration or has a crack syndrome.

What is involved?
Usually a crown is made and fitted in 2 visits. The first visit can take up to 90 minutes, and involves cutting the tooth, taking an impression and making a temporary crown. The second visit is the fitting appointment, and this usually only takes 20 minutes.

How long does it last?
With regular check ups and good home care, a crown can last a lifetime, but on average it will last around 8-10 years.


Bridge

A bridge, also known as a fixed partial denture, is a dental restoration used to replace a missing tooth by joining permanently to adjacent teeth or dental implants. There are different types of bridges, depending on how they are fabricated and the way they anchor to the adjacent teeth. Conventionally, bridges are made using the indirect method of restoration however, bridges can be fabricated directly in the mouth using such materials as composite resin.

Why get a bridge?
If you have a missing tooth, it can cause a malocclusion, or "bad bite", as teeth beside the gap can move and become misaligned. A bridge may be the best option if the neighboring teeth are weakened and require crowns, as it not only fixes the gap, but also protects the neighboring teeth.

What is involved?
A bridge preparation has the same steps as the crown, but more time consuming.

Is there other alternatives?
Missing teeth can also be replaced by a dental implant or removal appliance. Consult your dentist about which option best suits you, as everyone's treatment plan is different and tailored to there specific needs.
