Modern dentistry meets personalized care

We have invested in the latest dental technologies at Knoxville Smiles to enhance both the quality and comfort of your dental care. From intraoral cameras, cone-beam CT scans, and digital impressions to laser dentistry procedures, we are equipped with the tools and methods to deliver more precise care with reduced pain, bleeding, and recovery times.

However, having the right tools is only part of the equation—our personalized care approach is why we are one of the longest established dental practices in Knoxville and our patients keep coming back to us. We respect you as the individual that you are and keep an open line of communication with you through all stages of your care. Every treatment plan is completely customized to your oral health needs, desired results, and preferences for how to get there. From treatments such as dental implants or tooth-colored fillings and crowns that restore health and function to trial smiles, teeth straightening, and other cosmetic procedures, we focus on maintaining what is unique to your smile and combine it with our experience, artistry, and a keen sense of aesthetics to help you achieve a dazzling, functional smile.

Dental care for a wide range of needs

Your dental health starts with preventive care, which is the cornerstone of our practice.
