Implant-supported bridge: replacing multiple missing teeth
An implant-supported bridge replaces three or more missing teeth in a row using just two or three implants, not one implant per tooth. This guide walks through the procedure, the cost in Ontario, and how an implant-supported bridge compares with a traditional bridge. That way, you know what to expect before you book a consultation.

The basics
What is an implant-supported bridge?
A quick, plain-language answer before the details below.
An implant-supported bridge replaces several missing teeth in a row with one connected structure. Two or three titanium implants anchor into the jawbone at either end of the gap. A bridge of crowns then spans between them. Because the bridge shares chewing force across multiple implants, you typically need fewer implants than the number of teeth you are replacing.
Unlike a traditional bridge, an implant-supported bridge does not rely on your natural teeth for support. As a result, the healthy teeth next to the gap stay untouched. Compared with placing a separate implant under every missing tooth, an implant-supported bridge also means fewer implants, less surgery, and a lower total cost.

Candidacy
Are you a candidate for an implant-supported bridge?
Most adults missing several teeth in a row qualify. Here is the short version, plus where to go for the full picture.

The procedure
The implant-supported bridge procedure, step by step
Five stages, from your first x-ray to your final crown. Timelines vary by case, but this is the typical path.
1. Consultation
2. Extraction, if needed
Under local anesthetic, your dentist places two or three titanium implants at planned points along the gap. Most patients compare the sensation to a routine extraction.
5. Final crown
Once every implant has fully integrated, we attach the permanent bridge. It’s matched to the shade and shape of the teeth around it.
Comparing your options
Implant-supported bridge vs. traditional bridge
Both replace several missing teeth at once, but they anchor very differently. Here is what separates them.
A traditional bridge anchors its row of replacement teeth to the two natural teeth flanking the gap. To hold the crowns, your dentist files down those two teeth first. An implant-supported bridge, on the other hand, anchors entirely to implants in the jawbone. The bridge leaves everything next to the gap alone. That difference matters most once you start comparing durability and long-term cost.
Implant-supported bridge
- No grinding of healthy neighbouring teeth
- Preserves jawbone at every implant site
- Typically lasts decades with good care
Traditional bridge
- Requires filing down two healthy anchor teeth
- Does not stop bone loss along the gap
- Usually needs replacing every 10–15 years

Long-term outcomes
How long does an implant-supported bridge last?
Implant-supported bridges have a strong long-term track record. A retrospective study that followed patients for up to 14 years found a 98.6% survival rate for 3-unit bridges anchored on two implants, on par with single implants over the same period. Researchers also found fewer mechanical complications with the bridge design than with three separate splinted crowns. With regular checkups and good oral hygiene, most implant-supported bridges last for decades.
FAQ
Implant-supported bridge questions, answered
The questions patients ask most often before booking a consultation.
How many implants does an implant-supported bridge need?
Two implants can usually support a bridge of three to four replacement teeth. Larger gaps, or areas with weaker bone, sometimes need a third implant for extra support.
Is an implant-supported bridge better than individual implants?
Both are excellent long-term options. An implant-supported bridge usually costs less and involves less surgery, since not every missing tooth needs its own implant. Individual implants can be worth the extra cost when you want each tooth to function fully on its own.
Does getting an implant-supported bridge hurt?
Placement is done under local anesthetic, so you feel pressure rather than pain. Afterward, most patients manage any soreness with over-the-counter pain relief and return to normal activities within a day or two.
Will insurance cover my implant-supported bridge?
OHIP does not cover dental implants. Many private plans, however, cover parts of the treatment, such as the crowns or the initial x-rays. We check your benefits for you at your free consultation.
What happens if I wait to replace several missing teeth?
The jawbone along the gap begins to shrink without the stimulation tooth roots normally provide. Waiting can also let neighbouring teeth drift, which makes future treatment more complex and often more costly.
How long does an implant-supported bridge actually last?
With good oral hygiene, the implants themselves can last decades. Long-term research has followed successful implant-supported bridges for up to 14 years with survival rates above 98%. The bridge on top may need adjustment or replacement sooner, typically after 15 to 20 years.
