At 53 I thought the pain in one of my teeth was my first cavity. In fact, it was two major abscesses in my upper jaw. The result was the loss of teeth and I was devastated. I can’t say enough about the care and concern the staff showed me. I was a bit of a baby and from a small act like Oralgel before the freezing and stopping to check in with me, they made what was a traumatic diagnosis into something I could manage. Each step of the process was communicated and was experienced exactly the same way. Can’t recommend this office and team more. 10 stars!! Thank you Dr Allan and team! Very grateful to be your patient.

I have been going to St. Lawrence Dentistry for many many years and not one moment of regret. Hygienic, friendly professional atmosphere. You can count on transparency as well with your Dentist. I have worked first with Dr Allan Hawryluk Sr. and now his Son Dr Allan HawrylukJr. both delivered top notch service every single time with a smile. This is a Clinic that truly cares about your dental health and you will always be greeted with a smile. I have recommended them over the years and will continue doing so.

I have been attending this office for several years and always received superlative care. I’ve never waited more than a few minutes, and usually don’t have time to read a page of my book before I’m in the chair. Procedures are always thoroughly explained in advance, and step by step during the procedure. I, like many, have a “ dental phobia” about certain procedures like root canals, and these fears are treated with the greatest of respect and kindness. Everyone from the receptionists to the assistants, hygienists, and dentists themselves do a superlative job in caring for the patients. All the dental work I’ve had done there has been fantastic. I met Dr. Steve for the first time yesterday when he came in to check my teeth during a routine cleaning, and he clearly upholds the great traditions of this office. I would unhesitatingly recommend St. Lawrence Dentistry.
