Similarly to medical insurance, dental insurance entails paying monthly premiums in exchange for a set amount of dental care coverage in a given period (usually one calendar year). You’ll be able to access this coverage after paying a small deductible out-of-pocket.
However, whereas medical insurance is reactive, dental insurance is proactive. Instead of treating oral health problems after they’ve arisen, your insurance would prefer for you to prevent them in the first place. So, your plan is more likely to cover routine checkups than reparative services like fillings.
