A crown is a restoration that covers, or ‘caps’ a tooth to restore it to its normal shape and size, strengthening and improving the appearance of a tooth.
Crowns are necessary when a tooth is generally broken down and fillings won’t solve the problem. If a tooth is cracked, a crown holds the tooth together to seal the cracks so the damage doesn’t get worse.
Crowns are also used to support a large filling when there isn’t enough of the tooth remaining, attach a bridge, protect weak teeth from fracturing, restore fractured teeth, or cover badly shaped or discoloured teeth.
How is a Crown placed?
To prepare the tooth for a crown, it is reduced so the crown can fit over it. At Siana Dental we use 3Shape TRIOS technology rather than sticky impression materials to take an impression of the tooth once it is prepared. This technology will take 3D digital scans of the tooth that requires the crown. The 3D digital scans are then sent to the TRIOS lab via email where the crown will be created. The new crown or restoration will be fabricated and fitted in 48 hours from your appointment.
While you wait for your new crown, a temporary crown is fitted over the tooth until the permanent crown is made. On the next visit, Dr Max will remove the temporary crown and cement the permanent crown onto the tooth.
Will it look natural?
Yes. The dentist’s main goal is to create crowns that look like natural teeth. To achieve a certain look, a number of factors are considered, such as the colour, bite, shape, and length of your natural teeth. Any one of these factors alone can affect your appearance. All-ceramic crowns are preferable in the smile region. In certain circumstances, crowns can be made out of gold (or metal alloys) or a combination of porcelain fused to metal.
How should I take care of my crowns?
Besides visiting your dentist and brushing twice a day, cleaning between your teeth is vital with crowns. Floss or interdental cleaners (specially shaped brushes and sticks) are important tools to remove plaque from the crown area where the gum meets the tooth. Plaque in that area can cause dental decay and gum disease.
Dental bridges literally bridge the gap created by one or more missing teeth.
A bridge is made up of two crowns for the teeth on either side of the gap – these two anchoring teeth are called abutment teeth – with 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.
The Benefits of Dental Bridges are that they:
- Restore your smile.
- Restore your ability to properly chew and speak.
- Maintain the shape of your face, help to keep wrinkles away.
- Distribute the forces in your bite properly by replacing missing teeth.
- Prevent remaining teeth from drifting out of position.
- Are fixed in the mouth, and cannot be removed by the patient.
There are three main types of bridges
- Traditional bridges involve creating a crown for the tooth or implant on either side of the missing tooth, with a pontic in between. Traditional bridges are the most common type of bridge and are made of either porcelain fused to metal or ceramics.
- Cantilever bridges are used when there are adjacent teeth on only one side of the missing tooth or teeth.
- Maryland bonded bridges (also called a resin-bonded bridge or a Maryland bridge) are made of plastic teeth and gums supported by a metal framework. Metal wings on each side of the bridge are bonded to your existing teeth.
Dental bridges can last 5 to 7 years and even longer. With good oral hygiene and regular check-ups, it is not unusual for the life span of a fixed bridge to be over 10 years.
What is the procedure?
During the first visit, the abutment teeth are prepared. Preparation involves re-contouring these teeth by removing a portion of enamel to allow room for a crown to be placed over them. Using 3Shape TRIOS technology, we will create 3D digital scans of the teeth that require the bridge. The 3D digital scans are then sent to the TRIOS lab via email where the bridge will be created. The new restoration will be fabricated and fitted in 48 hours. We will usually make a temporary bridge for you to wear to protect the exposed teeth and gums while your bridge is being made.
During the second visit, your temporary bridge will be removed and the new permanent bridge will be checked and adjusted, as necessary, to achieve a proper fit.
