I need a root canal on my tooth. do i need consent from my insurence?

No: Get whatever you need done, done. If your insurance doesn't cover it, will you just leave the infection? Of course not. Do whatever you need to do to be healthy.

No: Unlike medical insurance, you do not need a pre-determination for dental insurance. You can request a pre-treatment estimate, but it important to understand that this is just an estimate. Insurance may pay more or less than the estimate. Also, it may take several weeks to get this back, so if you are in pain, it may be best to review your plan benefits yourself to determine an approximate cost.

Insurance: Generally yes. However never let a insurance company dictate your health needs. Only you and your dentist can decide what is the best course for you. You should have it done regardless, if you can financially afford it.

No: Most dental procedures do not need pre-approval from the insurance. However, even with a pre-authorization it's never a guaranty of payment to your dentist. Most dentists will have a policy stating that the ultimate financial responsibility is yours. So before any treatment is started i always suggest you ask how much is the work to be completed in case the insurance does not pay.

Contact insurance: They are the ultimate decider on all matters related to insurance claims and authorizations. Insurance is a contract between you and the insurance company, and the dentists opinion on whether it needs to be authorized doesn't matter.
