Why replace a missing tooth?
In a normal, healthy mouth, chewing function is well balanced since each upper tooth has proper contact and function with corresponding lower teeth. Because of this natural proper balance, undue strain or irritation on the gum tissue and bone is non-existent. Drifting or spreading of teeth does not occur and oral hygiene is easily maintained. But, thisnatural proper balance is quickly destroyed when a tooth is lost.
This is what can happen:
1.The opposing molar may super-erupt.
2.The unprotected ridge is subject to trauma.
3.The neighbor teeth tilt and proper functional balance is destroyed.
4.The drifting teeth create food impact areas where decay starts – or where Periodontal Disease can start.
5&6.Destruction to the bone will result as teeth drift and tip
A bridge is a structure, supported by teeth on either side of a space, which replaces a missing tooth or teeth.
- It is called a “bridge” because it spans the gap between two teeth. It is not removable by the wearer.
A bridge is a natural-looking replacement for missing teeth. It matches the adjacent teeth.
The first step is to prepare the supports for the bridge.
- Replacement Crowns over existing teeth are the usual supports for a bridge.
- The dentist pares down the tooth on each side of the gap, and then takes an impression of these pared-down teeth.
- Using this impression, the dental technician will make a replacement crown for each pared-down tooth, and will join them to an artificial tooth placed between them.
- The two replacement crowns, with the artificial tooth between them, form the bridge.
- The dentist will cement the bridge to the two pared down teeth
A dental implant is a “root” device, usually made of titanium, used in dentistry to support restorations that resemble a tooth or group of teeth to replace missing teeth.
