Dental insurance is financial protection for dental needs. The most beneficial part of a dental insurance plan is the fact that preventive care is usually free or very close to free. This allows a covered person to maintain their dental health rather than wait until something goes wrong. Most dental insurance plans will defray the costs of minor and basic work. That often includes fillings and simple extractions. Dental insurance plans will also provide good discounts on higher-end services such as root-canals and sometimes orthodontia. Dental insurance often covers only up to $1500 per person, however, so it is not a cure-all.
