Insurance & Financing

At our office, we understand working dental care into your budget can be tricky. If you have insurance, we’re happy to work with many major insurance plans. We can walk you through the details of what is covered and at what percent, and we’ll file and process claims for you. If you don’t have insurance or need additional help working a major treatment into your budget, we are happy to offer flexible financing options through CareCredit®. CareCredit offers low-interest financing and it’s easy to qualify and apply. If there’s anything we can do to help you make dental care more affordable, we would be happy to sit down and come up with a payment plan that works for you!
