Depending on the terms and conditions of your insurance policy, dental treatment like porcelain inlays and onlays fall into categories such as “basic” or “major” services.
Some insurance companies consider indirect fillings as basic treatment along with regular teeth cleaning, fillings, and other dental work. Further, they may have pre-set limits on the coverage they provide. You might be able to get about 80% reimbursement for the costs, which can vary according to the area where you live and the type of porcelain inlays or onlays you need. On the other hand, if the treatment falls in the major category, the insurance carrier may cover only 50% of the total expense. At the time of making your decision, check with your insurance provider first.
