Our patients say.

"Totally awesome office. Quick, clean, and professional. I've never felt so cared about or comfortable. From the doctor to the front office staff, they make sure to assist in any way. I have four kids and one is special needs. They were accommodating and considerate. The enthusiasm of their team made the difference. We appreciate their efforts!"

"Dr. Gaskill and his staff gave excellent care! I highly recommend Cedar Grove Dental. I was traveling past that area and they were able to schedule me last minute. I don’t usually like going to the dentist but my experience was Cedar Grove Dental went so smoothly."


"Dr. Gaskill and the team at Cedar Grove Dental are awesome. I am very happy with the care I have received there. My husband and I both got our teeth whitened by Dr. Gaskill before our wedding and were so happy to have nice teeth for our photos. Dr. Gaskill has also done several fillings on my teeth and was always ensuring I was comfortable, explained everything he was doing, and made sure all of my questions were answered. The rest of the staff there are really friendly. I would highly recommend anyone to get there dental care with Dr. Gaskill."

"Today was my first appointment at Cedar Grove Dental for a preventative cleaning and so far, so good! All of the staff was friendly and kind. Both they hygienist and the dentist seemed interested in me as a person and in my dental health, making sure all of my preexisting issues were being treated to a level that I wanted. The office is very flexible and let's me schedule appointments for my husband as well. Additionally, I was able to text message the office rather than needing to call which is something I really appreciate."

Emily C.

"I would recommend this dental office to all my friends and family they really care about their patients and work with you! I called because I had a wisdom tooth that was causing me pain and they got me in that same day! They took me back for an X-ray on my wisdom tooth and the Doctor said,” Yes I see why this would be bothering you do you want me to take it out today.” I thought he was joking because they said they wouldn’t have an opening for a couple weeks when I called to make my appointment. I was a little worried because I had my son with me but they were kind enough to bring him toys and apple juice and wait until someone came for him. I am so thankful for him and his staff for getting me in so quickly and taking my tooth out that same day. I will definitely be making Cedar Grove the place I take my family."
