Based on the type of Dental Insurance – you can have coverage for Preventative, Basic and Major dental issues covered.
Some plans may have waiting period for covering Major dental issues or can have a graded coverage, as you stay longer in the plan.
Unlike Medical Insurance where we have a Max-Out-of-Pocket (after which Insurance company pays all the expenses), Dental Insurance generally has a maximum that the insurance provider will pay and you as a client is responsible for the rest.
Orthodontics: Not all the plans covers Orthodontics. Some might cover it only for children. Please be careful while selecting the plan.
