We provide comprehensive treatment planning and use restorative and cosmetic dentistry to achieve your optimal dental health.

Education & Prevention

Education & Prevention

As a practice, we are true believers that preventative care and education are the keys to optimal dental health. We strive to provide “dental health care” vs. “disease care”. That’s why we focus on thorough exams – checking the overall health of your teeth and gums, performing oral cancer exams, and taking x-rays when necessary. We also know that routine cleanings, flossing, sealants, and fluoride are all helpful in preventing dental disease. Not only are we focused on the beauty of your smile, we’re also concerned about your health. A review of your medical history can help us stay informed of your overall health, any new medications, and any illnesses that may impact your dental health.

Uncompromising Safety

Uncompromising Safety

Infection control in our office is also very important to us. To protect our patients and ourselves, we strictly maintain sterilization and cross contamination processes using standards recommended by the American Dental Association (ADA), the Occupational Safety and Health Administration (OSHA), and the Center for Disease Control (CDC).
