While it is true that bonding is not always the best option, Dr. Thomas’ esthetic dental practice provides alternatives to bonding with veneers, crowns, bridges and implant crowns. Dr. Thomas’ practice goal is to always satisfy the patient’s desired dental outcome in the best way possible. Dr. Thomas feels that the best outcomes are achieved when each patient is provided with an in-depth understanding of the options and outcomes available to them. This understanding of options and outcomes allows each patient to feel confident to make an educated decision that is best for each patient’s personal situation.

Dr. Thomas has reduced her clinic hours to accommodate her family’s recent relocation to the United States. Dr. Thomas is committed to maintaining her role at Sierra Dental and continuing to provide esthetic and neuromodulator treatment to anyone who wishes to choose her to help them achieve the smile they dream of.
