Bridges
What is it?
A bridge is a type of restoration that is used to replace missing teeth, to improve aesthetics, function and to help maintain oral health. Missing teeth can lead to a variety of problems. When a tooth is lost, the surrounding teeth will actually shift. The adjacent teeth may tilt forward, and the opposing teeth may over-erupt. Even if just one tooth is lost, it can cause an increase in spaces between teeth, and change the bite and overall esthetics. This can also lead to changes in chewing function, promote decay due to changes in tooth contact, and may even promote periodontal disease. The standard of care to replace missing teeth is usually an implant, however alternatives to implants include bridges, and removable partial dentures.
Why do I need it?
A bridge is usually recommended in order to:
- Replace a missing tooth
- Restore proper occlusion
- Reduce unusual stresses on other teeth
- Prevent over-eruption of opposing teeth
- Prevent shifting and tilting of adjacent teeth
- Prevent dental decay
- Prevent periodontal disease
What does it involve?
A. Prior to initiating a bridge:
- Root canal therapy may be indicated.
- Crown lengthening may be indicated in some cases.
- Proper assessment of the periodontal health of supporting teeth will be conducted.
B. Preparing a bridge involves:
First appointment:
- Reducing the existing tooth structure in order to achieve adequate retention of the adjacent teeth.
- Taking impressions.
- Fabricating a temporary bridge.
- Shade selection.
***In between the 1st and 2nd appointment a patient may choose to have custom staining completed by the lab.
Second appointment:
- Removing the temporary bridge
- Metal Framework Try-in
- Recement temporary bridge
Third appointment:
- Removing temporary bridge
- Try-in finished crown
- Confirming the bite and contacts
- Cementing finished crown
How successful is it?
Bridges are not permanent and may need to be replaced. Proper oral hygiene is critical to the long term success of a bridge. Bridges are usually expected to last between 5-20 years as long as optimum oral hygiene is achieved. If the tissues surrounding the bridge recede with time as the patient ages a new bridge may be needed for aesthetic reasons.
What happens after?
Regular maintenance is critical, including a customized oral hygiene regiment and routine recall exams and cleanings which may range between 3-6 months as advised by the dentist. Oral care for a bridge includes, brushing after each meal, and flossing. It is critical to clean under the bridge using special floss to remove food debris and bacteria which may accumulate.
