Dental Implants vs. Bridges — Which Is Right for Your Missing Tooth?

A patient came in last month with a printout from the internet listing the pros and cons of dental implants versus bridges. He had decided on an implant before he sat down. After ten minutes of looking at the X-ray, we were recommending a bridge. The teeth either side of the gap had old, large fillings that were going to need crowns within five years anyway. Crowning two teeth twice — once for the fillings, then again to hold a bridge — is twice the work.

Replacing a missing tooth is one of the most over-simplified questions in restorative dentistry. The right answer depends on your bone, your bite, and what the teeth either side look like.

What each option actually is

A dental implant is a small titanium post placed into the jawbone where the natural root used to be. Bone grows around it over three to four months (osseointegration), and a custom crown is fitted on top. The result behaves like a single, free-standing tooth — it does not touch the teeth either side.

A bridge is a connected unit of three crowns: the false tooth in the middle, supported by crowns cemented onto the two adjacent teeth. Those two adjacent teeth are prepared (reduced in size) to seat the crowns. No surgery, no bone integration — start to finish in two to three weeks.

Both restore the function and look of the missing tooth. They do it differently, and the right one depends on what is happening either side of the gap.

When an implant is the right call

We recommend an implant when:

• The teeth either side are healthy. Untouched, unfilled, no large restorations. Preparing them for a bridge means cutting healthy enamel away — a permanent change to two good teeth, to fix a problem at a third.
• There is enough bone. A panoramic X-ray and sometimes a CBCT scan tell us this. If the bone has receded after a long-missing tooth, we may need a bone graft first — adds three to six months, but expands what is possible.
• The patient is a non-smoker, or willing to stop for the healing period. Smoking is the single biggest factor in implant failure. We are honest about this at the consultation.
• There is no untreated gum disease. Implants placed into inflamed gums fail. We treat the gums first, every time.

When a bridge is the right call

We recommend a bridge when:

• The adjacent teeth already need crowns. Large old fillings, cracks, prior root canal treatment — if those teeth are heading for crowns anyway, a bridge bundles the work.
• Bone volume is limited and grafting is not appropriate. Some cases of long-term tooth loss, or medical conditions that limit grafting, make a bridge the lower-risk path.
• The patient wants a faster, non-surgical solution. Two to three weeks vs. four to six months. There are valid reasons to prefer the faster path.

What an implant procedure actually feels like

Most patients picture the placement as the major appointment. It is not. It is roughly forty-five minutes under local anaesthetic, and the most common feedback is that it was less than the tooth extraction it replaced.

The timeline:

1. Consultation and planning (week 0). Examination, photographs, X-rays, CBCT scan. We map the bone in three dimensions and plan the implant position before we touch a scalpel.
2. Placement (week 1). Local anaesthetic, a small incision in the gum, the titanium post placed into the planned site, the gum closed with a few stitches. Forty-five minutes. Mild discomfort for two to four days, managed with over-the-counter pain relief.
3. Healing (weeks 1–14). Osseointegration. We see you once at two weeks for a check; otherwise the bone is quietly doing its work.
4. Crown placement (week 14–16). An impression of the integrated implant, a custom porcelain crown made and fitted. One short appointment to seat it. From here it is a tooth.

The questions we get most often

How long do implants last? Fifteen years and well beyond with normal care, in the published data — long-term studies report around 90% survival at the fifteen-year mark. The crown on top may need replacement at the fifteen-to-twenty-year mark — the implant post itself rarely does.

Is it more expensive than a bridge? Up front, yes. Over a thirty-year horizon, often less — bridges typically need replacement every ten to fifteen years, and each replacement is another procedure on the two anchor teeth.

Does it set off airport security? No. The titanium volume is too small to trigger detectors.

Will it look different from my natural teeth? A well-made implant crown is matched to the colour, shape, and surface texture of the teeth either side. In photographs and across a table, it is not visible.

When to come in for a consultation

If you have been living with a missing tooth — even one — please come in. The longer the gap is left, the more the surrounding teeth drift, the more bone is lost, and the more complicated the eventual solution becomes. A thirty-minute consultation tells you which option is right for your specific case, and we will give you a written plan with timelines and costs before you commit to anything.
