Children expect loose teeth. Adults should not. A permanent tooth that moves when you push it with your tongue is a sign that the structures holding it — gum, ligament and bone — are damaged, and the earlier the cause is found, the better the chance of keeping the tooth.
The main causes
Gum disease (periodontitis / pyorrhoea)
By far the commonest cause. Long-standing plaque and tartar inflame the gums, the gum detaches, and the bone that anchors the tooth is slowly lost. Teeth loosen, drift and develop gaps. Read about pyorrhoea.
Grinding and clenching
Heavy, repeated forces overload the ligament around the teeth. Teeth can become slightly mobile and sore, especially on waking.
Injury
A blow to the mouth can loosen a tooth without breaking it. It needs prompt assessment: a splint for a few weeks often lets the ligament heal.
Infection at the root tip
An abscess from an untreated dead tooth can make it feel raised and loose.
Pregnancy
Hormonal changes can temporarily loosen the ligaments slightly; good hygiene matters more than ever. See dental care during pregnancy.
Osteoporosis and some medicines
Lower bone density can contribute, particularly with gum disease present.
How it is assessed
The dentist measures the degree of mobility, checks the gums for pockets, tests the bite for high spots and takes X-rays to see how much bone remains and whether infection is present.
Treatment depends on the cause
- Gum disease: scaling and deep cleaning, laser gum treatment for infected pockets, then strict maintenance. Mildly loose teeth often firm up once inflammation resolves.
- Grinding: a night guard and bite adjustment to spread the load.
- Injury: splinting to adjacent teeth for a few weeks; root canal if the pulp has died.
- Infection: root canal treatment to remove the source.
- Splinting of several loose teeth to each other for stability in moderate gum disease.
When a tooth cannot be saved
If bone loss is too severe, keeping the tooth risks infection spreading to its neighbours. Extraction is then planned together with the replacement — most often a dental implant, placed once the gums are healthy. For several failing teeth, All-on-4 replaces the whole arch.
Common questions
Can a loose tooth tighten again? Yes, when the cause is inflammation, injury or overload and it is treated early. Teeth loosened by severe bone loss do not regain full support.
Should I wiggle it? No. Leave it alone, chew on the other side and have it checked within days.
Is it a dental emergency? A tooth loosened by injury is — see emergency dental care. A slowly loosening tooth should be seen within a week or two.
