Digital X-Rays
The benefits of digital x-rays allow us to reduce the radiation by 70-90% from conventional x-rays, view the x-ray as large as our monitor, and in seconds. No waiting, no solutions, just technology at its finest!
Crowns & Bridges
Our office only uses the highest quality crowns. We place the crown in temporarily for a week or two to give you time to inspect the shade and contour at your leisure and only once you’re satisfied will we place it in permanently.
One Visit Root Canal Treatments
Why do Conventional root canal? With advanced technology, we can do root canal treatment in one visit with little to no discomfort.
Cleaning Program
Our Enhanced Periodontal Program is designed especially for you. Each patient has different needs. If you want to keep those pearly whites, this is the program for you.
Implant Restorations
Tired of the spaces in your mouth? You have a choice. Come in and we’ll help you find the answers you are looking for. A consult with our office will help you choose the best option.
Oral Surgery
We do the oral surgery while you watch TV or listen to music. Referrals are rare. No need to travel to another office. We are here to make your stay as comfortable as possible. No hassles, no worries.
Teeth Whitening
This is the most conservative, yet cosmetic way of improving your smile. Dazzle your friends and family. We offer both in-house and take-home. For take-home, choose from a variety of flavors-mint, melon, tropical fruit, etc. No longer do you have to hide your smile.
Porcelain Laminates
This is for the person that wants family and friends to say, “Wow!” Porcelain laminates, sometimes referred to as “veneers,” are the most cosmetic way of transforming your smile.
