Loose Tooth in Adults: Causes and What to Do

A loose tooth is not normal in an adult. Adult teeth are meant to stay firmly anchored for life, so any wobble is your mouth telling you something has changed.

The good news is that many loose teeth can be saved when they are seen early. The less good news is that waiting rarely helps. Here is what causes a loose adult tooth, what to do today, and what we do about it in the chair.

Why is my adult tooth loose?

A tooth stays put because of the bone and gum tissue around its root. Anything that weakens that support, or puts too much force on the tooth, can make it move. The most common causes are:

• Gum disease. This is the number one cause. Bacteria break down the gum and bone holding the tooth. You may also notice bleeding gums, bad breath, or gums pulling back. Our guide to the signs of gum disease explains what to watch for.

• Teeth grinding or clenching. Constant pressure, often at night, can widen the ligament around a tooth. If you wake with a sore jaw, read about teeth grinding and how it is treated.

• Injury. A knock to the mouth from sports, a fall, or a hard bite can loosen a tooth even when nothing looks cracked.

• Infection. An abscess at the root can loosen the tooth, usually with throbbing pain, swelling, or a bad taste.

• Health and hormonal changes. Pregnancy can make gums swollen and teeth feel slightly mobile. Some conditions and medications that affect bone can also play a role.

What to do right away

You cannot fix a loose tooth at home, but you can protect it until you are seen.

• Leave it alone. Do not wiggle it with your tongue or fingers.

• Stick to soft foods and chew on the other side.

• Rinse gently with warm salt water, about half a teaspoon in a glass.

• Keep brushing softly and clean around the tooth so plaque does not build up.

• Use over-the-counter pain relief as directed on the label if it is sore.

• Book a dental visit within a few days.

When a loose tooth is an emergency

Call us the same day if the tooth loosened after a hit to the face, if you have swelling, a fever, pus, or severe pain. If swelling spreads to your face or neck, or you have trouble swallowing or breathing, go to the nearest emergency department.

How a dentist treats a loose adult tooth

Treatment depends on the cause. At your visit we examine the tooth, check how far it moves, measure the gum pockets, and take X-rays to see the bone.

Gum disease

A deep cleaning removes bacteria below the gumline so the gums can heal and tighten around the tooth. Advanced cases may need follow-up treatment or a referral to a periodontist.

Grinding

A custom night guard takes pressure off your teeth so the ligament can settle.

Injury

A loosened tooth can often be splinted to the neighbouring teeth for a few weeks while it heals.

Infection

An infected tooth may need a root canal, or an extraction if it cannot be saved.

If the tooth cannot be saved

Sometimes the bone loss is too advanced. We will talk you through replacement options such as an implant, bridge, or denture. Our comparison of a dental implant vs a bridge is a good place to start.

Can a loose tooth tighten up on its own?

Sometimes. If the cause is a mild injury or temporary inflammation, a tooth can firm up as the area heals. If the cause is gum disease or bone loss, it will not, and the longer it goes untreated, the less there is to save.

Loose adult tooth FAQ

Is a loose tooth in an adult an emergency?

It is urgent but not always an emergency. See a dentist within a few days. Go the same day if you have swelling, fever, pus, or severe pain, or if an injury caused it.

Can a loose adult tooth be saved?

Often, yes, especially when the cause is caught early. Gum disease treatment, a night guard, or splinting can all help a tooth stay in place.

Should I pull a loose adult tooth myself?

No. Pulling it can leave root fragments behind, cause infection, and remove a tooth that might have been saved.

Why does only one tooth feel loose?

A single loose tooth often points to a local problem such as an infection at the root, an injury, or heavy biting pressure on that tooth. A dental exam and X-ray will show which.
