From the moment I walked through the door, I felt like I mattered. Dr. Costa and his team explained everything about my treatment plan and broke everything down. I am beyond excited to get my smile back! I highly recommend anyone that is looking to get back their smile, to go and get a consultation. You will not be sorry.
I just read a review posted 2 months ago for a cleaning and x-rays that cost $377. My wife & I had the same today for a cost of $506 EACH!!! Nice folks and state of the art facility, but this cost seems totally outrageous.
This team of professionals was wonderful at taking care of my needs. Two months ago I had an emergency situation. I was in a lot of pain. I wasn't having any luck finding a dentist that could see me immediately. When my husband called this office and explained the situation, they made a point of working me into their schedule within the hour. The girls at the front desk were very welcoming and efficient with getting me in to see someone quickly. The hygienist and dentists all worked together to analyze my problem and came up with a plan to give me immediate relief. They all were very knowledgeable and communicated to me what had caused this emergency and what to expect in the coming days. Their after hours team helped me find a pharmacy that could do compounding and made sure that I had my medicine that night. This week I returned to get a routine cleaning and x-rays. Jessica, my hygienist, was very gentle and thorough. Kelsey help her do my charting. They communicated throughout the process what they were doing and why. Dr Bre came in to exam my mouth and was very gentle as well. The facility was very clean and was using cutting edge technology. I had a wonderful experience with both visits and plan to make them my new dentistry home.
I can’t say enough good things about Knoxville Smiles. From start to finish, the entire experience has been exceptional. Michael, Shannon, Jacob, Christian, Kim, McKinley, George, Ashley, Lindsay—and honestly everyone on the team—made me feel comfortable, informed, and well taken care of every step of the way. Full reconstruction was a big procedure for me, and they handled it with professionalism, precision, patience and genuine care. The communication was clear, the process was smooth, and the results so far have exceeded my expectations. You can tell this is a team that takes pride in their work and truly cares about their patients. If you’re considering major dental work or even routine care, I highly recommend Knoxville Smiles. You’ll be in very good hands. I’ll add few pictures after I get my final set of arches.
⭐️⭐️⭐️⭐️⭐️ — I can’t recommend Lacy enough! She was so easy to talk to and made me feel comfortable from the start. She was gentle during my cleaning, answered all of my questions, and never made me feel rushed. It’s clear she takes pride in what she does, and that made all the difference. She’s the kind of person who makes going to the dentist a much better experience.
