A dental bridge is a restoration designed to replace a missing tooth (or several teeth). Whether due to trauma, decay, or natural reasons, missing teeth can affect your appearance and oral functionality. Here's how dental bridges can help.
The different kinds of dental bridges
There are a few types of dental bridges with key differences that you need to know about when researching dental bridges.
Useful terms to know
Abutment: An anchor point of the bridge (usually a natural tooth or an implant)
Pontic: The false tooth that replaces the missing tooth
Traditional/Conventional Bridge
Uses crowns on either the missing tooth or teeth as anchor points (abutments).
The neighbouring teeth to the gap must be reshaped and prepared to fit the crowns securely.
Conventional bridges work extremely well but are the most destructive of your natural teeth, these days, they are only really offered when the neighbouring teeth to the gap would benefit from having crowns anyway or if implants are not possible for whatever reason.
Cantilever bridge
A cantilever bridge is a subtype for any bridge which only has an abutment on one side.
Maryland Bridge
Also known as a “sticky Bridge” or a “resin-bonded bridge”
Highly effective for front teeth without being destructive
Often made without reshaping any teeth
Primarily used for long-term temporary solutions, e.g., during the implant process
Not suitable for molars or back teeth
Maryland bridges are made up of a false tooth (pontic) with a wing, either metallic or made of white zirconia. The wing of the bridge is then stuck to the back of a neighbouring tooth for the bridge to be held in place

Implant bridges
Implant bridges work on the same principle as conventional bridges mentioned above but utilise implants for support instead of natural teeth.
How much do bridges cost?
Due to the variable nature of bridges, their cost depends on a number of factors mentioned below. As a very rough guide, you can budget for approximately £1000 - £15000 per unit (tooth) that needs to be restored.
Number of teeth involved.
Choice of materials and the intricacy of the procedure.
Aesthetic considerations based on tooth placement (front vs. back).
Dentist's expertise and experience.
Individual bite characteristics.
If you just have 1 missing tooth with a healthy mouth otherwise, often an implant will be more cost-effective than a bridge, especially for your back teeth.
Alternatives to Dental Bridges
Bridges are not the only way to replace missing teeth; you also have the alternative options below:
Dental Implants: A standalone solution, implants replace the root and crown of a missing tooth and don’t rely on anchorage from natural teeth on either side of the gap.
Dentures: Removable prosthetics that can replace multiple missing teeth made from either acrylic or Cobalt Chrome
Orthodontics: Occasionally, spaces can be closed using braces, although it's often lengthy.
Of course, you can leave your teeth as they are and accept a gap. However, leaving a gap in your mouth can lead to problems such as your dental arch collapsing and teeth drifting and moving.
The process of making dental bridge
Initial Consultation and Evaluation
Before anything else, a dentist will evaluate the health of the teeth that will anchor the bridge, known as the abutment teeth. This includes checking for gum disease, decay, and overall suitability. X-rays might be taken to ensure the supporting bone structure is strong.
Tooth Preparation
To ensure the bridge fits perfectly, the abutment teeth (those adjacent to the missing tooth or teeth) need some reshaping. This usually means removing a thin layer of enamel to make room for a crown that will be placed over them. This step is crucial for the bridge's stability.
Impressions/scanning and Molding
After reshaping, a mould or impression of the teeth is made. This impression acts as a model from which the dental bridge, pontic (false tooth), and crowns will be crafted. With technological advancements, modern dental clinics utilise digital scans to achieve this.
Temporary Bridge Fitting
While the final bridge is being made, a temporary bridge is put in place to protect the exposed teeth and gums. This interim solution also restores aesthetics and functionality to some extent and can help shape your gums to a more natural shape.
Crafting the Dental Bridge
The impressions or digital scans are sent to a dental laboratory where technicians craft the bridge. This process ensures the bridge will fit precisely and match the colour of the surrounding teeth. Materials commonly used include porcelain, ceramics, gold, or metal alloys, chosen based on location and aesthetic preferences.
Fitting the Final Bridge
Once the dental bridge is ready, the temporary one is removed. The new bridge is fitted, checked for accuracy in fit, and adjusted for any bite discrepancies. This step might require several visits to ensure the fit is perfect and comfortable.
Cementing the Bridge
When both the dentist and patient are satisfied with the fit, the bridge is cemented into place. This is a permanent procedure, ensuring the bridge remains stable and functional for a long time.
Aftercare and Review
Post-procedure, your dentist will guide you on cleaning and caring for your new bridge. Regular check-ups are vital to ensure your bridge's and adjacent teeth' health. Dental bridges can last over 10 years or more with proper care.
Looking after your dental bridge
A dental bridge is a significant investment in not just your smile but also your oral health. Like natural teeth, bridges require regular care to ensure they remain in top condition and serve you for many years to come. Here's how you can ensure your dental bridge remains in pristine condition:
Regular Brushing
Like your natural teeth, your dental bridge needs to be brushed twice daily using fluoride toothpaste. This helps remove plaque and prevent tooth decay, both in the teeth supporting the bridge and the false tooth (or teeth) itself.
Flossing
While the bridge may seem like one solid piece, it's vital to floss around the abutments (the teeth supporting the bridge) and under the pontic (the false tooth). Specialised floss, like superfloss or floss threaders, makes this task easier. They can slide between the gum and the bridge, ensuring all food particles and plaque are removed.
Avoid Hard or Sticky Foods
While dental bridges are sturdy, they are not indestructible. It's advisable to avoid chewing hard foods (like ice) or very sticky sweets that could potentially damage or dislodge the bridge.
Protect Your Bridge from Grinding
If you're prone to grinding your teeth at night, consider getting a mouth guard. This will help protect your natural teeth and bridge from undue pressure and potential damage.
Regular Dental Check-ups
Scheduling regular dental check-ups, typically every six months, is essential. This allows your dentist to inspect the bridge for potential issues. They can ensure the bridge is still fitting correctly and check the health of the supporting teeth and gums.
Professional Cleanings
In addition to your home cleaning routine, getting professional cleanings from your dentist or dental hygienist is crucial. They can clean areas that might be hard to reach, ensuring your entire mouth, including the bridge, remains clean.
Be Mindful of Potential Issues
Contact your dentist immediately if you notice any problems, like the bridge becoming loose or causing discomfort. Early detection and intervention can prevent more significant issues and extend the lifespan of your dental bridge.
Overview of dental bridges
With the right care, a dental bridge can last over a decade, making it a worthwhile investment in your oral health. Adopting a consistent and thorough cleaning routine ensures not only the longevity of your dental bridge but also promotes overall oral hygiene. Remember, the better you care for your bridge, the longer it will serve you efficiently and effectively.
