Dental insurance policies vary greatly, but many larger ones cover part of Invisalign treatment. Some providers consider Invisalign a cosmetic treatment and do not cover it. Most dental insurances cover between 25% and 50% of the treatment fee, leaving you with the remaining amount. In some cases, coverage can be higher. Depending on your insurance provider, your coverage may vary. Thus, even if you have the same dental insurance brand as someone else, their Invisalign treatment may be covered at 30% while yours may only be covered at 25%.   Dental insurance plans generally have a lifetime maximum, so if you exceed that amount, you will be responsible for any remaining costs. With some dental insurance coverage, you can expect to pay around $83 a month for Invisalign over 36 months.
