Our Philosophy

Queenston Dental is committed to helping our patients achieve the best possible outcome for their dental health in a calm and caring environment.

We strongly encourage our patients to have a regular comprehensive dental and periodontal exam which includes a thorough exam of the teeth and gums. These exams help us create a personalized treatment plan specifically for each patient. Regular appointments help minimize and sometimes eliminate the need for further dental procedures. All treatment options are explained thoroughly and and we are happy to answer any questions.
