Emergency dental symptoms
Loose adult tooth: why it happens and whether it can be saved
Adult teeth are not supposed to move. A tooth that wobbles after a knock, or has slowly loosened over months, is telling you about the bone and ligament holding it. Both problems can be treated.

What makes an adult tooth loose
A tooth is not cemented into the jaw. It is slung in its socket by thousands of ligament fibres running between root and bone, which is why a healthy tooth has a tiny amount of give, about a tenth of a millimetre, that you never notice. A tooth becomes loose for one of three reasons: the fibres have been torn or stretched (an injury), the bone they anchor to has been lost (gum disease), or the fibres are inflamed by infection at the root (an abscess), which pushes the tooth up in its socket so it feels tall and slightly wobbly.
Gum disease (periodontitis).
A knock or fall.
An abscess at the root.
Overload.
A fractured root.
How it started is the clue. Sudden, after a blow, means injury. Slow, with bleeding gums and no pain, means gum disease. Tender, tall and throbbing means infection.

Do not wiggle it: what to do now
- 01Leave it alone. Every push with a finger or tongue tears the fibres that are trying to reattach. Testing how loose it is makes it looser.
- 02If a knock has obviously moved the tooth out of line and it happened in the last hour, one gentle push back into position with clean fingers is fine. If it will not move easily, stop and leave it for us.
- 03Bite softly on a folded clean cloth to keep the tooth still on the way to the practice.
- 04Soft food only, and nothing on that side. Keep brushing the other teeth; rinse gently with warm salt water around the loose one.
- 05Paracetamol or ibuprofen as directed on the packet if it aches. Do not try to splint it yourself with glue or wire.
Examining and splinting a loose tooth
The emergency examination is £30 including X-rays and takes about 15 minutes. We measure how far the tooth moves and in which directions, run a fine probe around it to measure the gum pockets in millimetres, tap it, cold-test it (a tooth that has just been knocked may not respond for some weeks, which is normal), check whether it meets the opposite tooth too early, and take a digital X-ray. The X-ray shows the bone level, any root fracture and any abscess. What we find decides the treatment, which we price in writing before starting.
- After an injury. The tooth is numbed, eased back into position and held to its neighbours with a thin flexible splint for about two weeks, or four if the root is fractured or the tooth was pushed sideways. We check the nerve at follow-up visits and start root canal treatment only if it dies.
- An abscess. Drained through the tooth (emergency root canal stage 1, from £200) or through the gum. The looseness settles as the infection clears.
- Gum disease. Deep cleaning below the gum line under local anaesthetic, sometimes with a splint to share the load across neighbouring teeth, and a plan with our hygienist. Our gum health page explains what that involves. If most of the bone has gone, the honest option is extraction (£120–£260) before the infection spreads to the teeth either side.
- Overload. The high spot is adjusted, and a night guard made if you grind.
Visits after 6pm on weekdays and at weekends carry an additional out-of-hours charge.

Can a loose tooth tighten up again?
Yes, in three situations. After an injury, if the tooth is splinted promptly the torn fibres reattach and the tooth is usually firm again within a few weeks. After an abscess, the tooth tightens within days of drainage. After gum disease treatment, the inflammation settles, the gum shrinks back against the root and the tooth becomes noticeably firmer, although the bone that has gone does not grow back, so a tooth that was very loose stays a little mobile. It does not tighten if the root is fractured close to the crown, or if there is too little bone left to hold it.
What happens if a loose tooth is ignored
A knocked tooth left unsplinted heals in the wrong position, or not at all, and the nerve can die without any pain, turning the tooth grey and leading to an abscess months later. A tooth loosened by gum disease keeps losing bone until it falls out, and the infection in that pocket feeds on the teeth either side. It also removes the bone an implant would later need, so the replacement becomes harder as well as the tooth itself being lost. A loose tooth with an abscess follows the same path as any untreated infection: spreading swelling and, eventually, hospital. In every case, the treatment gets bigger and the options get fewer the longer it is left.
Questions, answered
Common questions
Can a loose adult tooth tighten up on its own?
A slightly loosened tooth after a minor knock sometimes does, if you leave it completely alone. A tooth loosened by gum disease or an abscess will not, because the cause is still there. Either way it is worth a £30 examination to know which you have.
Is a loose tooth always a sign of gum disease?
No. Gum disease is the most common cause in adults, but an injury, an abscess at the root, a fractured root or heavy grinding can all loosen a tooth. Slow looseness with bleeding gums points to gum disease; sudden looseness points to injury or infection.
Should I push a loose tooth back into place?
Only if a knock has clearly moved it out of line and it happened within the last hour: one gentle push with clean fingers, then leave it. Otherwise do not touch it. Wiggling it tears the fibres that are trying to heal.
Will a loose tooth have to be taken out?
Not usually. Teeth loosened by injury or infection are mostly saved. Extraction is the right choice when gum disease has taken most of the supporting bone, or a root is fractured near the gum line.
How long does a splint stay on a loose tooth?
About two weeks for a tooth loosened or knocked out by injury, and around four weeks if the tooth was pushed sideways or the root is fractured. The splint is a thin wire bonded to the front of the teeth, so you can eat soft food and brush normally.
Why is my tooth loose and painful?
A tooth that is loose, tender to bite on and feels taller than its neighbours usually has an abscess at the root pushing it up in its socket. Draining the infection, through the tooth or the gum, settles both the pain and the looseness.
