Insurance coverage for crowns and bridges varies in regard to the different types of dental policies available. The average policy won't cover pre-existing conditions, but will cover at least 50 percent of the total cost. Some policies limit coverage for crowns and bridges to once in five years to guard against unnecessary dental work. If your dentist recommends a specific treatment, contact your insurance provider and make a request for coverage based on the circumstances of your treatment. It's common for dental insurers to resist covering expenses that are covered under another form of insurance. For many people buying any type of dental insurance is only cost-efficient if they expect to spend a great deal of money on dental care in the near future. If you're interested in dental insurance, be sure to thoroughly discuss the different policies with your agent to make sure you get the coverage that best meets your needs. For further information about insurance coverage for crowns and bridges, consult a dentist or insurance agent near you.
