Dental bridges

Dental bridges are fixed dental restorations used to replace one or more missing teeth by literally bridging the gap between two adjacent teeth. They are typically anchored on either side by crowns on natural teeth or implants and consist of false teeth (pontics) in between.

‍

Purpose of Dental Bridges:

- Restoration: Replace one or more missing teeth to restore the function and appearance of the mouth.

- Prevention: Prevent remaining teeth from shifting out of position, which can lead to bite problems and jaw pain.

- Aesthetic Improvement: Enhance the appearance of the smile by filling gaps left by missing teeth.

- Improved Functionality: Restore the ability to chew and speak properly, which can be affected by missing teeth.

- Maintain Facial Structure: Help maintain the shape of the face, which can be affected by tooth loss.

Types of Dental Bridges:

1. Traditional Dental Bridges:

   - Description: The most common type, consisting of one or more pontics held in place by dental crowns on the abutment teeth.

   - Advantages: Strong and durable, suitable for replacing molars.

   - Disadvantages: Requires the removal of enamel from the adjacent teeth to place the crowns.

‍

2. Cantilever Bridges:

   - Description: Used when there are adjacent teeth on only one side of the missing tooth or teeth.

   - Advantages: Useful in areas of the mouth under less stress, like the front teeth.

   - Disadvantages: Not as stable as traditional bridges and not suitable for replacing molars.

‍

3. Maryland Bonded Bridges (Resin-Bonded Bridges):

   - Description: Consist of a false tooth supported by a metal or porcelain framework bonded to the back of adjacent teeth.

   - Advantages: Minimal preparation of adjacent teeth required, more conservative.

   - Disadvantages: Less durable, can become loose over time, not suitable for areas with heavy chewing forces.

‍

4. Implant-Supported Bridges:

   - Description: Supported by dental implants rather than crowns or frameworks. Implants are placed in the jawbone to act as anchors.

   - Advantages: Highly stable and durable, no need to alter adjacent teeth, suitable for multiple missing teeth.

   - Disadvantages: Requires surgery, longer treatment time, more expensive.

Procedure for Dental Bridges:

1. Initial Consultation and Diagnosis:

   - The dentist examines the mouth, takes x-rays, and discusses the best type of bridge for the patient’s needs.

2. Tooth Preparation (for Traditional and Cantilever Bridges):

   - The abutment teeth are prepared by removing a portion of enamel to make room for crowns.

3. Impressions:

   - Impressions of the prepared teeth and the gap are taken to create a precise model of the patient’s mouth. This can be done using putty or digital scanning.

4. Temporary Bridge:

   - A temporary bridge may be placed to protect the exposed teeth and gums while the permanent bridge is being made.

5. Fabrication of the Bridge:

   - The impressions are sent to a dental lab where the bridge is custom-made. This process typically takes 2-3 weeks.

6. Fitting the Permanent Bridge:

   - The temporary bridge is removed, and the permanent bridge is fitted. The dentist checks the fit and bite, making adjustments as necessary.

   - Once satisfied with the fit, the bridge is permanently cemented in place.

‍

Post-Procedure Care:

1. Sensitivity:

   - Some sensitivity to temperature changes and pressure is normal after placement and should subside within a few days.

2. Oral Hygiene:

   - Brush twice a day and floss daily to maintain the health of the bridge and surrounding teeth. Special floss threaders or interdental brushes may be recommended to clean under the pontics.

3. Diet:

   - Avoid chewing hard foods and substances to prevent damage to the bridge. Sticky foods should also be avoided as they can dislodge the bridge.

4. Regular Dental Visits:

   - Regular check-ups and cleanings are essential to monitor the health of the bridge and surrounding teeth.

‍

Longevity and Maintenance:

1. Durability:

   - Dental bridges can last between 5 to 15 years or longer, depending on the material used, oral hygiene practices, and habits such as teeth grinding.

2. Replacement and Repair:

   - Bridges may need to be replaced or repaired due to wear, damage, or changes in the underlying tooth structure. Regular dental visits help to identify any issues early.

‍

Complications and Considerations:

1. Tooth Decay:

   - Decay can develop in the abutment teeth if proper oral hygiene is not maintained.

2. Gum Disease:

   - Maintaining good oral hygiene is crucial to prevent gum disease, which can affect the longevity of the bridge.

3. Bridge Loosening:

   - Over time, the cement holding the bridge in place can weaken, leading to loosening. Prompt dental care is required to re-cement the bridge.

4. Discomfort or Pain:

   - If the bridge does not fit properly, it can cause discomfort or pain. Adjustments by the dentist may be necessary.

5. Allergic Reactions:

   - Rarely, some patients may have an allergic reaction to the materials used in the bridge. Alternative materials can be chosen if needed.

‍

Conclusion:

Dental bridges are an effective and reliable solution for replacing missing teeth. By understanding the types of bridges available, the procedure, and post-care recommendations, patients can make informed decisions and ensure the longevity of their dental restorations. Regular dental check-ups and good oral hygiene are essential to maintaining the health of bridges and overall oral health.
