Two cleanings per 12 months are covered at no charge (after the $10 office visit fee). An additional cleaning per year is also available for diabetics and expectant mothers at a $40 copayment. Please keep in mind that this procedure can only be applied to patients with healthy gingiva (gums). Your dentist may recommend a more comprehensive cleaning to bring your gums into a healthy state of maintenance. Additional charges may apply for these procedures. There is a $10 office visit charge for each visit to a participating dentist.
