About Our Plans

The Smile Advantage Plan is a membership-based dental savings plan, for patients without insurance, that provides the quality care they deserve at a price they can afford. Members pay an annual fee to receive regular exams, cleanings and X-rays along with access to significantly reduced rates on all other restorative and cosmetic dental procedures performed in our office. Plus, the plan offers many benefits including no annual caps, no limits, and no waiting periods. This provides for quick access to the care you need!



Our Child Membership Plan is intended for patients 13 and younger.  The plan provides an affordable option for families to keep up on regular screening appointments for their children.  It's important that children start visiting the dentist at a young age and learn the importance of dental hygiene to maintain good oral health and prevent problems from occurring in the future.

    Frequently Asked Questions

    Why do you offer the Smile Advantage Plan?
    Over the years, we’ve found that more and more of our patients are choosing not to visit their local dental offices due to expensive fees and a lack of employer-provided dental health coverage. Routine exams and basic cleanings at the dentist’s office can prevent most oral health problems from arising and can even prevent other serious and life-threatening systemic health concerns from developing.
    Do I have to be an existing patient?
    No. The plan is open to new and existing patients of the offices we serve. We are accepting new patients to the savings plan.
    Are there any family discounts?
    It’s up to each individual practice to determine if family discount will be offered. To see our complete membership pricing, click HERE to download our patient contract.
    My employer suggested I take advantage of the plan. Now what do I do?
    If you are applying for Smile Advantage through an employer-supported promotion, the process remains the same. Simply DOWNLOAD and complete the official forms.
