A loose adult tooth: what should you do?

If an adult tooth has become loose, contact a dentist promptly and ask for an urgent assessment. Avoid repeatedly pushing it with your tongue or fingers to check how far it moves. A loose tooth does not always have to be removed, but finding the cause early helps your dentist plan appropriate care.

A baby tooth becoming loose at the expected stage of development is different. If a child’s tooth has loosened after an injury, seek urgent dental advice rather than assuming it is ready to fall out.

When is it urgent?

A tooth that becomes loose after a knock needs urgent dental care. Contact your dentist or NHS 111, particularly if there is pain, bleeding or a change in the bite. New mobility with swollen gums or signs of infection also needs prompt attention.

Go to A&E or call 999 for serious facial injury, bleeding that will not stop, or severe swelling with difficulty breathing or opening an eye. NHS emergency dental guidance explains where to get help.

Until you are assessed, avoid biting on the affected tooth and choose foods that are easy to chew. Do not try to glue or splint it yourself.

Why can an adult tooth become loose?

Teeth have a small amount of natural movement within their supporting tissues. A noticeable new change, however, should be checked rather than diagnosed at home.

Periodontitis can damage the gums and bone supporting a tooth. It may cause mobility even without severe pain. Treatment aims to control the disease and help preserve the remaining support; it cannot promise to save every tooth.

An injury can damage the tissues around a tooth or fracture the tooth itself. An examination, and sometimes X-rays, help establish what has happened.

Forces on the teeth, including clenching or grinding, may contribute to problems in some cases. They should not be assumed to be the only explanation without checking gum health and other possible causes.

Orthodontic treatment deliberately moves teeth, and some temporary mobility can occur. Contact your orthodontic team if movement seems excessive, a tooth hurts or something has changed suddenly. Do not adjust the brace yourself.

Is the whole tooth loose, or a restoration?

A loose crown or filling can feel as though the tooth is moving. Decay, a fracture or infection may also affect a previously treated tooth. Root canal treatment does not routinely make the whole tooth loose, so new mobility afterwards should be assessed.

Tell the dentist when you first noticed the problem, whether there was an injury and whether you have pain or bleeding gums. They will examine the tooth, its supporting tissues and your bite. A particular electronic measuring device is not required for every assessment.

What treatment might help?

Treatment depends on the cause. Gum disease may require professional cleaning, support with daily care and reassessment. An injured tooth may need repositioning or a temporary splint in selected cases. A splint supports a tooth while it heals; it does not itself cure gum disease or rebuild lost bone.

A loose restoration may need repair or replacement. If the tooth cannot be maintained, your dentist will explain extraction and suitable replacement options. Ask what can realistically be achieved before deciding.

Once the immediate problem has been treated, follow the cleaning advice and review schedule you are given. Good daily care and appropriate check-ups help reduce future problems, but they do not replace an assessment of a tooth that has already become loose.
