Dental Implants vs Bridges vs Dentures

Comparing options for replacing missing teeth

The main difference is what holds the new tooth: dental implants are held by the jawbone, a bridge by the teeth on either side of the gap, and a denture by the gums (and sometimes by clasps on remaining teeth). That one difference drives most of the others, from what happens to your neighbouring teeth to how you clean it.

This page compares the three point by point so you can ask sharper questions at your appointment. For the different implant designs, see the guide to types of dental implants.

How each option is supported

Dental implants sit in the jawbone. A small post does the job of a tooth root and holds the replacement tooth without leaning on the teeth around it.

Dental bridges are held by the natural teeth next to the gap. In a conventional bridge, those teeth are reshaped and crowned, and the false tooth spans the space between them. A resin-bonded ("Maryland") bridge, used for front teeth, is cemented to the back of the neighbouring teeth instead; a cantilever bridge is anchored on one side only.

Dentures rest on the gums and the bone underneath. A full denture replaces every tooth in an arch; a partial denture replaces some and clips onto the teeth you still have.

Upfront cost vs long-term value

Implants usually cost more at the start than a bridge or a denture. Over the years, the picture can shift.

A bridge may need more work if one of its supporting teeth develops a problem. A conventional denture often costs less up front, but relines, adjustments and eventual replacement add up as the jaw changes shape.

The way to compare is with written estimates for each option that's suitable for you, including upkeep. Our guide on how to compare dental implant quotes shows what to check. For fee ranges, insurance and public coverage, see dental implant costs in Ontario on our sister site.

Impact on neighbouring teeth

This is often the deciding factor when the teeth beside a gap are healthy.

• Implants stand on their own and don't require any work on the teeth next to them.
• Conventional bridges need the teeth on either side of the gap reshaped to act as anchors, even if they're healthy. Resin-bonded bridges for front teeth attach to the back of the neighbouring teeth; ask whether one would suit your gap.
• Dentures can put force on the natural teeth they touch, especially partial dentures held by clasps.

Comfort, stability, and function

Implants are held in the jawbone, so the teeth on them stay put when you chew and talk.

Bridges are fixed and stable, but only as long as the teeth holding them stay healthy and strong.

Dentures can shift when you eat or speak, more so as the jaw changes shape over time. Implant-supported dentures reduce that by attaching the denture to implants.

Bone changes over time

After a tooth is lost, the jawbone in that spot can lose volume over time.

Implants sit in the bone where the root used to be. Your dentist can explain what that means for the bone at your own site.

Bridges span the gap without anything in the bone below the false tooth, so the bone there may change over time.

Dentures sit on top of the gum. As the jaw changes underneath, the fit loosens, and the denture needs adjusting or relining.

Maintenance expectations

All three need regular care. What that looks like differs:

• Implants: Daily brushing and cleaning, professional cleanings, and periodic checks of the implant and the tooth on it.
• Bridges: Careful cleaning under and around the bridge, with floss threaders or small interdental brushes.
• Dentures: Daily cleaning, overnight soaking, and periodic professional adjustments as the jaw changes.

Which option could suit you?

There's no single right answer. It comes down to the health of your remaining teeth, your bone, your budget, and what you care about most.

• If keeping healthy neighbouring teeth untouched matters most, implants may be the better fit.
• If you want to avoid surgery or need a faster result, a bridge may be appropriate.
• If cost up front is the main concern, a denture is usually the most affordable starting point.

Think about your daily routine, how much cleaning you're prepared to do, and how much a stable bite matters to you. For more on weighing it up, see are dental implants worth it.
