Complete Forms in Advance

All of the forms we need to open your patient file are available for you to fill out in advance of your visit. View our registration forms below to access either option. Filling out these forms in advance helps streamline your first visit to our Sumter periodontal office.

Prepare for Your First Visit

We understand that your first visit to a new Sumter periodontist can generate a little bit of anxiety – especially if you haven’t seen a dentist in a while. Our goal is to make every patient visit a positive experience!

Financial Options

Our practice is proud to offer comprehensive periodontal and dental implant services in Sumter. We provide a wide range of financial options for our patients to help them manage their dental care. For your convenience we accept cash, checks, money orders, and credit cards. We also file claims with most major forms of dental insurance and offer financing through Care Credit and Sunbit Financing.

The cost of your treatment will vary depending on your individual needs and treatment plan. We will discuss with you the cost of your treatment and each of your available payment options before you begin, so that you can make the best choice for you.

Dental Insurance

Dental insurance policies often provide some form of coverage periodontal treatment. Please bring all dental benefit information and cards to your examination appointment. Upon request, we will submit a claim to predetermine your insurance benefits; however, this is not required by most insurance companies.

As a courtesy to our patients with dental benefit plans, we submit necessary claim forms, clinical documentation, and other information to your insurance company. Upon receipt of an insurance payment, any balance due will be billed to you; if you have deposited an over-payment, it will be refunded to you.

Most dental insurance policies are limited. Your coverage may only pay for a portion of the procedure(s) to treat your dental problems. Dental “benefit plans” are not insurance, and normally offer “discounts” only at participating dental practices. Medicare also does not cover most dental procedures.
