Can a broken tooth be glued back?
Often, yes. When a front tooth breaks cleanly and the piece is intact, a dentist can bond it back on with dental adhesive and composite, which keeps your own enamel, shape and shine. The piece should be kept in water, not glued at home. It suits clean breaks above the gum; splits into the root need other treatment. At Creative Arts in Dubai the tooth and nerve are checked with an X-ray first.

What should you do in the first hour after a tooth breaks?
- Find the piece. Look on the floor, in your mouth and, if your lip is cut, check the cut: small fragments sometimes end up inside the lip. Tell the dentist if a piece is missing and your lip is swollen or cut.
- Keep it moist. Rinse off any dirt by holding it, not by scrubbing it, and put it in a small container of clean water, or saline if you have it. A piece that dries out turns chalky white; it can often be rehydrated, but moist is better.
- Do not glue it yourself. Household superglue and pharmacy adhesives are not made for teeth. They irritate the exposed dentine and gum, and a thin layer of glue stops the piece seating precisely, which makes professional reattachment harder.
- Protect the tooth. Avoid very hot, cold or sweet food on that side, and cover a sharp edge with sugar-free gum or orthodontic wax if it cuts your tongue.
- Check for other injuries. Loose or displaced teeth, a tooth pushed up into the gum, or a bite that suddenly feels wrong all need prompt examination.
Then contact the clinic during opening hours, daily 10:00–20:00, and say that a piece has broken off and you still have it. Our emergency dentist page explains what happens at an urgent visit, and our broader dental first aid guide covers other injuries.
When to go to a hospital instead
A head injury, any loss of consciousness, vomiting or confusion after a fall or blow, a suspected broken jaw, bleeding that does not stop with firm pressure, or facial swelling with difficulty breathing or swallowing need a hospital emergency department first. The broken tooth can be dealt with once you are safe. If the whole tooth has come out, follow our knocked-out tooth steps instead, because timing matters much more.
Which broken teeth can have the piece reattached?
Reattachment works best for clean breaks of front teeth above the gum. An examination and X-ray decide which row fits.
| Type of break | Can the piece be bonded back? | Usual plan |
|---|---|---|
| Small chip of enamel only | Rarely worth it: the piece is too thin to bond well | Smoothing the edge or a small composite bonding repair |
| Corner or edge broken through enamel and dentine, piece intact | Usually yes | Reattachment with adhesive and composite, then review visits |
| Break exposing the nerve (a pink or bleeding spot) | Often, once the nerve has been treated | Nerve assessed first; then reattachment or bonding |
| Break running below the gum line | Sometimes, but it is more complex | May need gum or other procedures first; sometimes a crown |
| Split down into the root, or a root fracture | No: the problem is in the root | Assessment for whether the tooth can be kept; otherwise replacement |
| Broken cusp of a back tooth with a large old filling | Uncommon | New filling or crown, depending on what remains |
If the break is in a tooth that has had a root canal, the plan is different; see our guide to a root canal tooth that broke.
Can my dentist reattach the broken piece, and how is it done?
The International Association of Dental Traumatology guidelines (2020) state that after a break through enamel and dentine, an intact fragment can be bonded back onto the tooth, and that a dry fragment should first be soaked in water or saline for about 20 minutes. Reattachment is a well-established technique; it is not a temporary trick.
The visit usually runs like this. The dentist examines the tooth and its neighbours, takes an X-ray to look at the root and nerve, and checks that the piece fits. While the fragment rehydrates, the tooth is cleaned and isolated from saliva. Both surfaces are prepared with a mild etch and a dental adhesive, the piece is seated in exactly the right position and set with a curing light, and a thin layer of composite may be added along the line to hide it and add strength. Finally the bite is checked so the repaired edge does not take a direct hit when you close.
Follow-up matters as much as the repair. The same guidelines recommend clinical and X-ray checks at about six to eight weeks and one year, with more visits if the nerve was exposed, because a nerve can react to an injury weeks later. A tooth that darkens, becomes tender to bite or develops a gum boil should be seen promptly.
What if the broken tooth exposed the nerve?
A pink or red dot, or a spot that bleeds, in the middle of the break means the nerve, or pulp, is exposed. It is usually very sensitive to air and cold. The nerve needs attention before the piece goes back on. Depending on how large the exposure is, how long ago it happened and the age of the tooth, the dentist may try to keep the nerve alive with a protective dressing (our guide to vital pulp therapy explains these approaches), or root canal treatment may be the more predictable choice. Whether a nerve-preserving approach suits your tooth, and whether it is done here or by referral, is decided at the examination.

Explore restorative dentistryHow long does a reattached tooth piece last?
There is no fixed lifespan. A reattached piece can last for years, but the bond line is a weak point compared with an uninjured tooth, so another knock, biting into something hard, or opening packets with your teeth can detach it again. When that happens, the piece can often be bonded back a second time if it is intact.
A few things affect how the result looks and holds: a fragment that dried out may look slightly whiter at first and usually blends back as it rehydrates; a thin composite layer along the line helps hide it; and grinding or a deep bite that loads the edge raises the risk of it coming off. If the piece fails repeatedly, or the tooth later needs other work, composite bonding, a veneer or a crown can replace it.
Bonding or crown if the broken tooth can't be reattached?
If the piece is lost, crushed or does not fit, these are the usual options, from least to most tooth removed.
| Option | When it fits | What to expect |
|---|---|---|
| Composite bonding | Small to medium breaks with plenty of tooth left | Built up in tooth-coloured composite in a single visit; may need polishing or repair over time |
| Porcelain veneer | Larger breaks on the front surface, or when several front teeth are being improved together | A thin ceramic shell made by the lab after a design; some enamel is usually prepared |
| Crown | Large breaks, a tooth that is also heavily filled, or after root canal treatment | Covers the whole tooth; made by Creative Art Dental Lab in the same building, typically in 3–5 working days |
| Post, core and crown | Root-treated teeth that have lost most of their crown | See our post and core guide |
Our page on a chipped or broken tooth covers all types of chips and breaks, including back teeth.
Who repairs broken teeth at Creative Arts?
At Creative Arts in Dubai, broken teeth are examined and repaired by Dr. Marina Antoniuk and Dr. Julia, who also assess and treat the nerve with a dental microscope when it is involved, and by Dr. Khalid Saeed, co-founder of the clinic, for larger restorations such as veneers and crowns. If a root-treated tooth has broken, our guide to a root canal tooth that broke explains the different questions those teeth raise.
