Dr. Brad Perrett, DDS
TOP FAMILY DENTIST IN COLORADO SPRINGS
In a world that is often rushed and hurried, Dr. Perrett maintains a philosophy of personalized care that really stands out to his patients. This is evident in the way his team provides patient-centered care that focuses on the comfort and quality of his dentistry and the overall wellbeing of his patients. He describes his philosophy of care as “compassionate, conservative, and thorough.” His conservative and biomimetic style means he engineers dentistry to save the maximum amount of natural tooth structure and then restores teeth back to a more natural, long lasting state. Using very advanced dental adhesion techniques, the need for future dentistry is drastically reduced. His personal goal is to help people keep their teeth for their lifetime by eliminating future cycles of retreatment.
Dr. Perrett often states that he loves the creativity and artistry of modern dentistry. He enjoys providing comprehensive and preventative dental treatments including the management of complex dental cases, placement and restoration of dental implants, cosmetic dental treatments, dentures, root canals, TMJ therapy, and biomimetic restorative dentistry.
Dr. Perrett and his wife Andrea were married in 2019. They are both Colorado natives and love to spend time with family and friends. They both enjoy the outdoors whether it be yardwork, snowboarding or camping.
