Tooth knocked out? First aid for a dental accident.

A fall, sport, an accident — and a tooth is out. With the right approach, a permanent tooth can often be saved. The most important steps.

Now every minute counts

If a permanent tooth is completely knocked out, the chances of re-implantation are best if it reaches the dentist within about 30 to 60 minutes and correctly stored. Stay calm — and follow the steps below.

First aid step by step

  • Touch the tooth only by the crown, never by the root
  • Do not scrub, do not disinfect, do not dry — the fine cells on the root must stay alive
  • Store the tooth moist: ideally in a tooth rescue box, otherwise in UHT milk or your own saliva (cheek) — never in water and never dry
  • Go to the dentist or emergency service immediately — the faster, the better the prognosis
Tooth rescue box

A tooth rescue box from the pharmacy keeps the root cells alive the longest. For families and sports clubs, a small, sensible addition to the first-aid kit.

Milk tooth or permanent tooth?

A knocked-out milk tooth is usually not re-implanted, so as not to endanger the underlying tooth germ — but the injury should always be checked. A permanent tooth, on the other hand, is saved if possible.

Who pays for a dental accident?

Dental accidents are among the few cases that, depending on the situation, are covered by accident insurance (for employees via the employer) or health/supplementary insurance. Keep receipts and a record of how the accident happened. More in the article supplementary dental insurance Switzerland.
