Why a tooth supraerupts
Teeth are held in place partly by contact with the tooth opposite. When that tooth is extracted and the space is left empty, the tooth that used to meet it loses its stop. Over months and years it can slowly move toward the gap, and the gum and bone around it can follow, so more of the root shows. Dentists also call it overeruption.
It is most common with lower back teeth that are lost and not replaced, which lets the upper tooth drift down. It can also happen with gum disease, which weakens the support and lets teeth move. Our page on missing teeth explains why gaps change the whole bite.
Why it matters
A supraerupted tooth is more than a cosmetic change. It may hit the gum or the opposite jaw when you chew, and it can throw the bite off so the jaw works awkwardly. The exposed root surface is more prone to decay and sensitivity, and the gap beside it traps food.
It also takes up the space needed for a replacement. A tooth that has drifted into the gap may leave too little room for a crown, bridge or implant. That is why the order matters: the drifted tooth often has to be dealt with before the replacement is made.
How supraerupted teeth are managed
The best answer is to prevent it by replacing a missing tooth early. Our guide on dental implants vs a bridge compares the two usual options, and the dental implants page explains how implants work, and our guide on implant-supported bridges shows a third route when several teeth are missing.
Once a tooth has drifted, options depend on how far. A small change can be reshaped by polishing the biting surface. A larger one can be reduced and covered with a crown. A tooth that has moved a long way can sometimes be pushed back with orthodontic treatment, using braces or small anchoring screws. If it has lost too much support, or cannot be corrected, extracting it and replacing both gaps is the other route.
A dentist decides from an examination and X-rays, looking at the bite, the gum and the bone. Do not leave a gap for years: the longer it stays, the more teeth around it can move.
| Option | When it is used | Limit |
|---|---|---|
| Replace the missing tooth early | To prevent drifting in the first place. | Does not undo drifting that has already happened. |
| Reshaping the tooth | A small amount of drift. | Removes enamel, so only a little can be taken. |
| Crown | A larger change, or a worn or weak tooth. | Needs a healthy tooth underneath. |
| Orthodontic intrusion | A tooth that can be moved back into line. | Takes time and needs good gum health. |
| Extraction | A tooth that has lost too much support. | Leaves another gap to fill. |

Common questions
Is a supraerupted tooth the same as an overerupted tooth?
Yes. The terms are used for the same thing: a tooth that has moved further out of its socket than it should. Dentists also say extruded tooth. All describe a tooth that has drifted toward an empty space.
Can a supraerupted tooth be pushed back?
Sometimes. Orthodontic intrusion with braces or small screws can move a tooth back, depending on how far it has gone and the health of the gum and bone. Reshaping or a crown is often easier for a smaller change.
Does a supraerupted tooth need to be removed?
Not always. Many can be reshaped, crowned or moved back. Removal is considered when the tooth has lost too much support, is decayed beyond repair, or blocks the replacement of the missing tooth.
Can I get an implant if a neighbouring tooth has drifted?
Often yes, once the space has been restored. The drifted tooth may need to be reshaped, crowned or moved first so there is enough room. A dentist will check the space and the bone before planning.
