A cantilever dental bridge is a dental prosthesis used to replace a missing tooth. Unlike traditional bridges supported by crowns on both sides of the gap, a cantilever bridge is anchored on only one side. This makes it a suitable option in specific scenarios where traditional bridges might not be viable. This article will cover cantilever dental bridges, including their benefits, drawbacks, procedures, and costs.
What is a Cantilever Dental Bridge?
A cantilever dental bridge is a fixed dental restoration that uses a single abutment tooth to support an artificial tooth (pontic). It is typically used when there are adjacent teeth on only one side of the missing tooth.
The bridge is bonded to a single adjacent tooth using dental cement, creating a seamless appearance and restoring functionality.
Benefits of Cantilever Dental Bridges
1. Preserve Natural Teeth
Unlike dental implants, cantilever bridges do not require drilling into the jawbone. This preserves the integrity of the surrounding teeth.
2. Less Invasive
The procedure is less invasive compared to traditional bridges as it involves fewer teeth.
3. Cost-Effective
Generally, cantilever bridges are more affordable than implants or traditional bridges.
4. Quick Procedure
The process can be completed in a few dental visits making it a convenient option for many patients.

Drawbacks of Cantilever Dental Bridges
1. Limited Use
Cantilever bridges are not suitable for all cases particularly if the supporting tooth is not strong enough.
2. Potential for Damage
The single-point support can lead to increased stress on the abutment tooth, potentially causing damage over time.
3. Less Durable
Compared to traditional bridges, cantilever bridges may have a shorter lifespan due to the uneven distribution of bite forces.
Procedure of Cantilever Dental Bridges
1. Initial Consultation
The dentist evaluates your oral health and discusses the best options for replacing your missing tooth.
2. Preparation of the Abutment Tooth
The adjacent tooth is prepared by removing a portion of its enamel to create space for the crown that will support the bridge.
3. Impression
An impression of your teeth is taken to create a custom-fit bridge.
4. Temporary Bridge
A temporary bridge may be placed while the permanent bridge is being fabricated.
5. Fitting the Permanent Bridge
Once ready, the permanent bridge is fitted and adjusted for comfort and functionality.
6. Bonding
The bridge is bonded to the abutment tooth using dental cement.

Caring for Your Cantilever Dental Bridge
Proper care is essential to ensure the longevity of your cantilever dental bridge. Here are some tips:
1. Maintain Good Oral Hygiene
Brush and floss regularly to prevent plaque buildup around the bridge.
2. Regular Dental Check-Ups
Visit your dentist for regular check-ups and professional cleanings.
3. Avoid Hard Foods
Avoid biting down on hard foods or objects to prevent damage to the bridge.
4. Use Mouthguards
If you grind your teeth at night use a mouthguard to protect your bridge.
Conclusion
A cantilever dental bridge is an effective and less invasive solution for replacing a missing tooth especially when there are adjacent teeth on only one side. While it has its limitations, the benefits often outweigh the drawbacks for many patients. By understanding the procedure, costs, and care requirements, you can make an informed decision about whether a cantilever dental bridge is the right choice for you. Always consult with your dentist to explore all available options and determine the best course of action for your dental health.
FAQs
Q1: How long does a cantilever dental bridge last?
With proper care, a cantilever dental bridge can last between 5 to 15 years. Regular dental visits and good oral hygiene can extend its lifespan.
Q2: Is the procedure painful?
The procedure is typically not painful, as local anesthesia is used to numb the area. Some patients may experience mild discomfort after the procedure, which can be managed with over-the-counter pain relievers.
Q3: Can a cantilever bridge be used for multiple missing teeth?
Cantilever bridges are generally used for a single missing tooth. For multiple missing teeth, other options like traditional bridges or implants may be more suitable.
Q4: What materials are used for cantilever bridges?
Cantilever bridges can be made from various materials, including porcelain, ceramic, metal, or a combination of these materials. The choice of material depends on the location of the bridge and patient preferences.
Q5: Can I eat normally with a cantilever dental bridge?
Yes, you can eat normally after the bridge is fitted. However, it’s advisable to avoid very hard or sticky foods that could damage the bridge.
Q6: How do I clean under a cantilever bridge?
Cleaning under a cantilever bridge requires special flossing techniques or interdental brushes. Your dentist will provide instructions on how to maintain oral hygiene around the bridge.
