I have been going to Keep28dental for over 12 years. With its late closing I am able to book appointments after 6pm... allowing me to complete my day at work and have my dental needs taken care of. The staff is great, friendly and welcoming. The office are diligent at following protocols to avoid incidents of Covid. 👍read more

I am the worst person in the chair. I have very sensitive teeth and absolutely hate going to the dentist. Keep 28 is... the best! Kerry is friendly and welcoming. Neal and Francis are fabulous dentists always taking the time to make sure I am super comfortable. I have been going to Keep 28 for over 20 years and even though I live an hour away from the office now , I make the trip to Newmarket because they are so fabulous and I could not imagine going anywhere else!!read more
