Implant vs bridge

By About Dentist editors · Updated · How we research costs

Both replace a missing tooth. An implant replaces the root and stands on its own; a bridge anchors a false tooth to crowns on the neighboring teeth.

Compared

Typical cost $3,000-$6,000 $1,500-$5,000
Time to finish 3-9 months 2-3 weeks

Typical lifespan Implant often decades; crown 10-15+ years 10-15 years

Choose an implant if

Neighboring teeth are healthy, you have enough bone (or can have a graft), and you want the longest-lasting option.

Choose a bridge if

Neighboring teeth already need crowns, you want it done quickly, or implants aren’t possible.

Frequently asked questions

Is an implant or a bridge cheaper?

A bridge is usually cheaper upfront. Over a lifetime, an implant can cost less because it often lasts longer and doesn’t involve the neighboring teeth.

Does insurance cover implants or bridges?

Many plans cover both as major work at about 50%, up to the annual maximum. Some older plans exclude implants: check your benefits.

Can I get a bridge if my neighboring teeth are healthy?

Yes, but they must be reshaped for crowns, which is why many dentists prefer an implant when the neighboring teeth are healthy.

How long does an implant take compared with a bridge?

A bridge usually takes two visits over two to three weeks. An implant typically takes three to nine months because the post needs time to fuse with the bone.
