Missing Teeth: Causes and Treatment Options

Also known as: tooth loss, gaps in teeth

Teeth can be lost to gum disease, tooth decay or an injury. A gap can make chewing and speaking harder, and nearby teeth can shift and the jawbone can shrink. Missing teeth can be replaced with a dental implant, a bridge or dentures, and a dentist helps you choose.

Why Teeth Are Lost

Adults can lose teeth because of:

  • Gum disease: An infection of the tissues that hold the teeth in place, caused by plaque that builds up on the teeth. If it is not treated, it can spread to the bone that supports the teeth, and in the most serious cases, teeth may become loose or need to be removed.
  • Tooth decay
  • An injury

People who smoke or used to smoke tend to have fewer of their own teeth left.

How Common Is Tooth Loss?

Tooth loss in adults has decreased since the early 1970s. These are averages for adults in the United States.

AgeAverage number of teeth (of 32)No natural teeth left
20 to 6426About 2%
65 and over21About 15%

What Happens If a Missing Tooth Is Not Replaced?

Nearby teeth can shift into the gap. The jawbone where the tooth used to be gradually shrinks, which can give the face a sunken look. A gap can also make it harder to chew and speak, and some people feel self-conscious about how it looks.

When to See a Dentist

A dentist can check your teeth and gums and talk you through your options. Make an appointment if any of these sounds familiar:

Treatment Options for Missing Teeth

Which option fits depends on how many teeth are missing, the health of your other teeth and your jawbone, and your dentist helps you decide.

Missing Teeth: Frequently Asked Questions

How should I care for dentures?

Brush them every morning and evening, and rinse them after meals. Take them out at night, unless your dentist advises otherwise, and keep them in water. Do not clean them with toothpaste, which can damage them.

Can I get dentures right after teeth are removed?

Yes. Immediate dentures can be fitted on the same day the teeth are removed, so you are not without teeth while you heal. As your mouth heals and changes shape, they often need to be adjusted or replaced within about a year.

How long do dentures last?

With good care, dentures last on average 7 to 10 years. Regular dental checkups help make sure they still fit well.
