Payment and Insurance

We welcome dental insurance. As a courtesy to you, we are happy to bill your insurance company for you. We will answer all of your questions and call your insurance provider to verify benefits.

Many of our patients are covered by a dental insurance plan. This serves as a valuable way to help pay for the cost of dental care. It is important to understand that services are rendered to the patient, not the insurance company. Thus, the insurance company is responsible to the patient, and the patient is ultimately responsible to the doctor for payment.

Your treatment plan will include a breakdown of all applicable fees, and we will inform you of all costs before treatment is administered. We require full payment at the time of treatment. For your convenience, we accept Visa, MasterCard, Discover and debit cards.

We submit all insurance claims for you. We will fully attempt to help you receive full insurance benefits; however, you are personally responsible for your account, and we encourage you to contact us if your policy has not paid within 30 days.

We work with numerous insurance plans and are happy to assist you by verifying your coverage. We do not participate in Health Management Organizations; however, we will be happy to file your insurance claims for you. We accept checks, cash or credit cards. We also offer a flexible payment plan. Please see our Financial Coordinator for details. We are happy to file insurance for your reimbursement as long as you have a plan that allows you to choose your own dentist.
