What is in our control, we will guarantee. The quality of our workmanship and materials, is our responsibility, and we will fix or repair any work that fails, here in our office. We will always do the right thing, standing behind the work done at our office. This guarantee covers any problems that later become evident, like a crown coming off, a filling that falls out, or a denture or crown that needs to be adjusted. If a treatment, like a root canal, needs to be repeated, there will be no additional charge to fix work under guarantee.
