Multiple Tooth Dental Implants

Replacing several missing teeth

Several missing teeth in a row don't usually need one implant each. Two or more implants can hold a fixed bridge that fills the whole gap. If only one tooth is missing, a single tooth implant is the more likely option.

The bridge is anchored in the jawbone, so it doesn't lean on your remaining natural teeth for support.

When multiple tooth implants may be considered

This usually comes up when two or more teeth next to each other are missing. That kind of gap often follows:

• Decay that spread across several teeth
• An injury to one part of the mouth
• Advanced gum disease
• Infection that meant several teeth had to come out

Whether it works for you depends on how many teeth are missing, where they are, how much bone there is, and the health of the rest of your mouth. When all the teeth in a jaw are affected, full arch dental implants may be considered instead.

How they work

Implants go into the jawbone at planned points along the gap. Once they've integrated with the bone, a bridge is made and attached to them.

Each tooth in the bridge is shaped and coloured to match your own. The number of implants depends on how many teeth are being replaced, the bone at each spot, and the forces that part of the mouth takes when you chew.

Comparison to traditional bridges

A conventional bridge is held by crowns on the natural teeth at each end of the gap. Those teeth have to be reshaped to take the crowns, even if they were healthy.

An implant bridge leaves the neighbouring teeth alone. Systematic reviews that compare the two report high survival for both tooth-supported and implant-supported bridges. The practical difference is mainly what each one asks of the teeth next to the gap, and whether you're willing to have surgery.

Bone and gum health

Implants need enough bone to sit in securely. Bone where teeth have been missing for a while can thin, which may mean it has to be rebuilt before implants go in.

If there isn't enough, bone grafting may be suggested. The gum matters too: healthy gum seals around each implant and helps protect it.

Treatment planning

The plan for a multi-tooth gap is based on:

• How many teeth are missing and where
• The quality and volume of bone along the gap
• The condition of the teeth and gums around it
• Your bite and how you chew
• Your medical health, including anything that affects healing

Imaging is used to plan where each implant goes so the bridge has the support it needs. For the other designs a dentist might suggest, see the guide to types of dental implants.

Longevity and care

With good care, implants can stay in function for many years, though results vary. The bridge on top wears and may need repairs or, eventually, replacing.

Looking after it means:

• Daily brushing and flossing, including under the bridge with floss threaders or a small brush
• Regular check-ups and professional cleanings
• Avoiding heavy forces such as tooth grinding
• Looking after your gums and general health

Is this option right for everyone?

No. Your bone, medical history, gum health and goals all have to line up. The guide on who is a good candidate for dental implants explains what's checked.

Ask about the alternatives too, including a conventional bridge or a partial denture, and why one is suggested over another. If you get more than one proposal, our guide on how to compare dental implant quotes shows how to line them up, including the number of implants each one uses.
