What happens during my first visit?

A patient’s first visit to our office will typically consist of a consultation to explain the diagnosis and discuss treatment options. In many cases, treatment will be provided immediately following the consultation, however those patients with complex medical histories or treatment plans may require a second appointment at which treatment will be provided.

Before any procedure requiring anesthetic, it is important to alert staff members if you have a medical condition that may be of concern. These may include hearts disease, high blood pressure, artificial heart valves and joints, diabetes, rheumatic fever, etc. Also please let us know if you are on any medication that may affect the procedure(i.e. heart medications, aspirin, blood thinners, etc.) or if you require medication before dental cleanings (i.e. antibiotics premedication.)

At your first appointment, you will be asked to provide as much of your medical history as possible. This may include things such as a referral slip from another doctor and any dental X-rays in your possession, a current list of medications you are taking, and completed medical or dental insurance forms (if applicable). This helps us avoid unnecessary delay when processing dental insurance claims.

Please note: A parent or guardian must accompany patients under 18 during their first visit to our office.

Additional Insurance Information

We gladly accept most major dental insurance plans.

We will help to maximize your insurance reimbursements, as well as send you a monthly statement regarding your account. Remember that insurance companies will typically respond within four to six weeks, so please call our office at 408-730-5800 if your insurance payment has not appeared on your statement in that time. The remaining balance(s) after payment is the patient’s responsibility, and we thank you in advance for promptly meeting your obligations.

Options for a monthly payment plan are available, but must be arranged prior to your procedure or through CareCredit®.

Please remember that patients are ultimately responsible for their fees incurred, regardless of insurance coverage.

Our staff is available to answer and assist you with questions regarding your account, so please contact us at 408-730-5800. Don’t hesitate to make the call, as we can often help clear up simple misunderstandings.
