What is a dental bridge?
Dental bridges serve as a solution for replacing missing teeth.
By anchoring onto neighbouring teeth or dental implants, these prosthetics "bridge" the gap, restoring both function and aesthetics to the patient's smile.

Dental bridges are custom-made, ensuring they blend seamlessly with the patient's natural teeth in terms of shape, size, and colour. This personalized approach not only enhances the smile's appearance but also provides a comfortable fit, crucial for long-term wear and functionality.
The importance of replacing missing teeth cannot be overstated, as it prevents the remaining teeth from shifting, maintains facial structure, and ensures proper chewing and speech.
What are the main 4 types of dental bridges?
The four main types of dental bridges include:
Traditional dental bridge, where a false tooth is held in place by dental crowns on adjacent teeth.
Cantilever bridge, which is supported by a crown on only one side of the missing tooth.
Maryland dental bridge, using a metal or porcelain framework bonded to the backs of adjacent teeth, provides a less invasive solution.
Implant-supported bridge, which uses dental implants as anchors for each missing tooth, offering unparalleled stability and mimicking natural tooth roots for the most natural feel and function.
Traditional dental bridge
The traditional dental bridge is a prevalent choice for replacing one or more missing teeth. It consists of one or more pontics (false teeth) that are held firmly in place by dental crowns attached to the abutment teeth on either side of the gap. This type of bridge requires the abutment teeth to be reshaped and reduced in size to accommodate the crowns, ensuring a secure and stable fit.
Traditional bridges are made from a variety of materials, including porcelain fused to metal or ceramics, chosen to match the colour and appearance of natural teeth. They are favoured for their durability, functionality, and the way they seamlessly blend with natural teeth, offering a solution that is both aesthetic and functional.
Cantilever dental bridge
The cantilever dental bridge is an alternative solution when there are teeth present on only one side of the missing tooth or teeth gap. Similar to the traditional bridge, the pontic in a cantilever bridge is held in place by a dental crown that is cemented to a single abutment tooth. Due to its design, the cantilever bridge applies force on the anchor tooth, making it crucial that the supporting tooth is healthy and strong.
While cantilever bridges are a viable option in cases where a traditional bridge is not possible, they are generally used for teeth that undergo less stress, such as the front teeth, to minimize the risk of damage to the supporting tooth.
Maryland dental bridge
The Maryland dental bridge represents a conservative alternative to traditional bridges, notably preserving the structure of adjacent teeth. This type of bridge utilises a framework made from metal or porcelain that is bonded onto the back of the adjacent teeth, effectively anchoring the pontic in place without the need to file down the neighbouring teeth.
Maryland bridges are often used to replace front teeth, where the biting forces are minimal, and the preservation of tooth structure is paramount. The non-invasive nature of this bridge makes it a preferred choice for patients seeking a less permanent solution that maintains the integrity of their natural teeth.
Implant-supported bridge
Implant-supported bridges offer the most advanced solution for replacing multiple missing teeth, providing unmatched stability and longevity. This type of bridge is supported by dental implants rather than crowns or frameworks. An implant is surgically placed for each missing tooth, and these implants serve as the foundation for the bridge.
Implant-supported bridges are highly durable, function like natural teeth, and do not require support from adjacent natural teeth, thus preserving the natural tooth structure. This option is particularly beneficial for patients looking for a long-term solution that closely replicates the feel, function, and appearance of their natural teeth, making it an ideal choice for both aesthetic and functional tooth replacement.
The pros and cons of a dental bridge
Dental bridges offer the significant advantage of restoring aesthetics and function following tooth loss. They prevent remaining teeth from drifting, which could lead to bite issues and further dental problems. Bridges are also less invasive than implants and do not require surgery, making them a quicker solution for many.
However, bridges also have their downsides. They typically require the alteration of adjacent healthy teeth to support the bridge and may not last as long as dental implants. Regular maintenance is crucial to ensure their longevity, and they might need to be replaced every 5 to 15 years.
How are dental bridges fitted?
The process of fitting a dental bridge typically involves two or more visits to the dentist.
The process usually consists of the following steps:
The abutment teeth are prepared by reshaping these teeth to accommodate the crowns.
Impressions of the teeth are then taken, which serve as a model from which the bridge, false tooth, and crowns will be made by a dental lab.
During the second visit, the custom-made bridge is checked for fit and comfort, with adjustments made as necessary.
Once the fit is verified, the bridge is cemented into place, restoring the patient’s smile and functionality.
The procedure is relatively straightforward but requires precision and customization to ensure the bridge functions correctly and matches the natural appearance of the patient's teeth.
How long does it take to recover after a dental bridge procedure?
Recovery time after a dental bridge procedure is generally short, with most patients resuming their normal activities within a day. After the placement of a dental bridge, some patients may experience mild soreness or sensitivity around the treated area, which typically subsides within a few days.
Over-the-counter pain relievers can manage any discomfort, and patients are advised to eat soft foods and avoid extremely hot or cold beverages for a short period after the procedure. It's crucial to follow the dentist's care instructions to ensure a smooth recovery and the longevity of the bridge.
What are the alternatives to dental bridges?
While dental bridges are a popular solution for missing teeth, several alternatives exist, including dental implants and partial dentures. Dental implants offer a permanent solution, replacing the tooth root with a titanium post that integrates with the jawbone, topped with a crown for a natural look and feel. Partial dentures are removable appliances that can replace multiple teeth and are less invasive than bridges or implants.
Each alternative has its benefits and considerations, such as cost, treatment duration, and patient preference, making it essential to consult with a dental professional to determine the best option based on individual needs and oral health.
