Gentlewave Technology
GentleWave technology presents a breakthrough alternative to standard root canal treatment. A GentleWave procedure delivers a vortex of fluids through the tooth, cleaning debris and thoroughly disinfecting the canal and canal walls. In most cases, a GentleWave procedure can be completed in just one session and there's less chance of failure over time. Many patients describe the experience as comfortable. More info can be found at GentleWave.com.
Insurance
We are in network with Delta Dental, though we bill to most insurance companies. Patients will be expected to pay an estimated copay at the time of service based on insurance coverage. Please expect a bill post-treatment for any difference and feel free to reach out with any questions. More information is available in our Financial Policy.
