A traditional bridge replaces a missing tooth by crowning the teeth on either side, which means reshaping healthy teeth. A Maryland bridge, also called a resin-bonded or adhesive bridge, takes a much more conservative approach. It is particularly popular for replacing a single missing front tooth, including in young patients who are not ready for an implant.
A Maryland bridge consists of a replacement tooth with one or two thin wings attached to the back. These wings are bonded to the inside surfaces of the neighbouring teeth using strong dental adhesive. Because the wings sit behind the teeth, they are not visible from the front, and the neighbouring teeth need little or no drilling.
Maryland bridges work best for replacing front teeth, where biting forces are lower. The neighbouring teeth should be healthy, with enough enamel to bond to and minimal fillings. They are a popular option for teenagers who have lost a tooth or have a congenitally missing tooth, as they can be used until the jaw has finished growing and an implant can be considered.
The biggest advantage is that natural tooth structure is preserved. Treatment is usually quick, often completed in two appointments, and no surgery is needed. Maryland bridges are generally more affordable than implants and can be reversible or replaced with an implant later if desired.
Because they rely on adhesive bonding, Maryland bridges can occasionally come unstuck, particularly if the bite is heavy or the patient grinds their teeth. They are less suitable for back teeth where chewing forces are strongest. If a bridge debonds, it can often be re-cemented if it is undamaged.
Clean under the replacement tooth daily using superfloss or interdental brushes. Avoid biting directly into very hard foods with the bridge. Regular check-ups allow your dentist to check the bond and the health of the supporting teeth.
Very little. The wings are bonded to the back surfaces of the teeth with minimal or no drilling, so most natural tooth structure is preserved.
With good care, many last for many years. Occasionally a bridge may debond and need re-cementing.
It is generally better suited to front teeth, where biting forces are lower. Back teeth usually need a traditional bridge or implant.
