Dental accident

What is a dental accident?

A dental accident is an accident in which teeth, dentures or the jaw are damaged. Typical examples are a knocked-out front tooth after a bicycle fall, a broken tooth after a blow during sport, or a damaged crown after a fall on the stairs.

What matters is the definition of an accident in social insurance law. An accident is the sudden, unintentional harmful effect of an unusual external factor on the body. So three points are important: the event happens suddenly, you did not intend it, and an external factor acts on you in an unusual way. If a tooth breaks because it has been weakened by decay or wear, the unusual external factor is missing. That is then not a dental accident but a case of ordinary dental costs, which you usually pay yourself or through dental insurance.

Dental accidents are governed by special rules in Switzerland because basic health insurance otherwise only covers dental treatment in exceptional cases. With an accident it is different: the treatment of accident damage to the masticatory system is covered, either through accident insurance under the Accident Insurance Act (UVG) or through the accident cover of basic health insurance.

How it works

Which insurance pays depends on whether you are insured under the UVG:

In the event of an accident, basic health insurance covers the same benefits as for illness, plus the treatment of damage to the masticatory system. However, it only steps in to the extent that no accident insurance pays. If you are fully insured under the UVG, you can therefore exclude accident cover from basic health insurance and save on premiums. If your UVG cover ends, for example when you lose your job, the health insurer’s accident cover automatically applies again; you must, however, report this to your insurer.

Reporting is important. Employees must report an accident that requires medical or dental treatment without delay to their employer or the accident insurer. If you are insured through basic health insurance, report the accident to your health insurer. Have the damage documented by the dentist as quickly as possible.

Legal basis

Art. 4 of the Federal Act on the General Part of Social Insurance Law (ATSG) defines an accident as the sudden, unintentional harmful effect of an unusual external factor on the human body that results in impaired health or death.

In health insurance, Art. 1a para. 2 let. b of the Health Insurance Act (KVG) applies: social health insurance only pays benefits for accidents to the extent that no accident insurance covers them. For accidents, Art. 28 KVG refers to the same benefits as for illness. Art. 31 para. 2 KVG adds that basic health insurance also covers the costs of treating damage to the masticatory system caused by an accident. Under Art. 8 KVG, accident cover can be suspended if you are fully insured under the UVG; Art. 10 KVG governs the end of the suspension.

In accident insurance, Art. 10 para. 1 let. a UVG gives entitlement to outpatient treatment by a doctor or dentist. Under Art. 10 para. 2 UVG you can choose your dentist freely. Under Art. 1a UVG, employees in Switzerland and people receiving unemployment insurance benefits are insured. Part-time employees are only insured against non-work-related accidents if they work at least 8 hours a week for the same employer (Art. 13 para. 1 UVV). The duty to report is set out in Art. 45 UVG.

Example: bicycle fall with a broken front tooth

Two people fall off their bicycles in 2026 and break a front tooth. In both cases the dentist’s bill is an assumed CHF 2,000. The co-payment follows from Art. 64 KVG and Art. 103 KVV.

What this means for you

1. Report the accident immediately. If you report it late, you risk discussions about whether it really was an accident.
2. Record what happened. Note the date, place and sequence of events, record any witnesses and have the dentist document the damage immediately.
3. Ask for a cost estimate. For larger work such as implants or crowns, it is worth getting a cost estimate that the insurer checks before treatment.
4. Check your accident cover. If you are insured under the UVG, you are paying unnecessarily for accident cover in basic health insurance. The exclude accident cover tool helps you find out whether you can exclude it. The premium calculator shows premiums with and without accident cover.
5. Keep an eye on long-term consequences. Accident damage to teeth can make further treatment necessary years later. Keep all documents.

Common mistakes

• Not reporting the accident. Without a report there is no proof, and the insurer may ask questions about how it happened.
• Reporting tooth decay as an accident. A tooth that breaks because of decay or wear is not an accident.
• Contacting the wrong insurer. Employees working at least 8 hours a week report the accident to their employer, not to their health insurer.
• Forgetting accident cover after your job ends. If you have excluded accident cover, you must report the end of your UVG cover to your health insurer.
