Dental Implant or Bridge: How to Choose

Bridge or implant: the short answer

If you have lost a tooth, the two fixed ways to fill the gap are a bridge or an implant. Deciding between a bridge or implant is easier once you see how each one is held in place. Both stay in your mouth all the time, unlike a removable partial denture, and both can look and work much like a natural tooth.

Here is the key difference. A bridge leans on the teeth next to the gap for support. An implant stands on its own, anchored in the jawbone. That one difference shapes almost everything else: how long treatment takes, what happens to the neighbouring teeth, and how you clean it.

Why it's worth filling the gap

A missing tooth is not only about looks. The American Dental Association notes that the teeth around a gap may shift, and that bone can shrink where a tooth used to be. A missing back tooth can change how you chew, and a large gap may affect how you speak.

Not every gap has to be filled, though. Some people leave a space at the very back of the mouth, especially when the opposing tooth is also gone. Your dentist can tell you whether your gap is likely to cause problems over time.

How a dental bridge works

A fixed bridge, sometimes called a fixed partial denture, is one solid piece. A false tooth sits in the middle, held by crowns on the teeth at each end. Those end teeth are called abutments. To make room for the crowns, the dentist reshapes them by removing some of their outer layer.

Treatment usually takes two or more visits over a few weeks. First, the teeth are prepared and a digital scan or impression is taken. You wear a temporary bridge while a lab makes the final one. At the next visit, it is checked, adjusted and cemented. Only a dentist can remove a fixed bridge.

How a dental implant works

An implant is a small post, usually titanium, placed in the jawbone where the root used to be. Over the following months, bone grows around it and holds it firmly. This is called osseointegration. Once it has healed, a crown is attached to it.

Some people can receive a temporary tooth on the day the implant goes in. Others wear a temporary option while they heal. Before placement, the dentist checks the bone with X-rays or 3D imaging. If there isn't enough bone, extra steps may be needed first, which adds time.

Implant vs bridge: what to weigh

Here is how the two compare on the points patients ask about most:

• Neighbouring teeth: a bridge needs them reshaped and crowned; an implant leaves them alone.
• Time: a bridge is often done in a few weeks; an implant usually takes several months from placement to final crown.
• Surgery: a bridge needs none; an implant is placed in a minor surgical procedure under local anaesthetic.
• Bone: an implant needs enough healthy bone; a bridge does not, though bone under the false tooth may slowly shrink.
• Cleaning: a bridge needs floss threaders or small brushes to clean under the false tooth; an implant is brushed and flossed much like a natural tooth.
• Health: chronic conditions such as diabetes, and tobacco use, can slow healing after implant surgery.

When a bridge may suit you

A bridge can make sense when the teeth on either side already have large fillings or crowns. Covering them with new crowns may help protect them anyway. It may also suit people who would rather avoid surgery, need the gap filled sooner, or have bone or medical factors that make an implant harder.

Keep in mind that a bridge depends on its anchor teeth. If one of them later develops decay or gum disease, the whole bridge can be affected. Careful cleaning under the false tooth and regular checkups help protect it.

When an implant may suit you

An implant is often worth a close look when the teeth beside the gap are healthy and untouched, because there is no need to file them down. It can also work where there is no tooth at the end of the gap to support a bridge.

You'll need healthy gums, enough bone and the patience to wait through healing. If you smoke, your dentist may talk with you about quitting. Implants still need daily care: infection in the gum around an implant can cause bone loss, just as it can around a natural tooth.

Coverage and your next step

Private dental plans differ a great deal in how they pay for bridges and implants, so a predetermination before treatment is useful. Public coverage is limited too: when we checked the CDCP Dental Benefits Guide in October 2026, bridges and implants were both listed as outside the plan.

If you're in Aurora or nearby, our dentists can examine the gap, take digital X-rays and walk you through a dental implant vs bridge plan for your own mouth. Dr. Kourosh Rahimi, whose training focuses on implant dentistry, is part of our team. You'll get a written estimate for each stage before any treatment begins.
