I went to this dentist a few months ago to have a couple of teeth extracted, while my kids have been going there for years i was a new customer,i called up told them what was needed and made the appointment. it was a no hassle affair.
They are in Dorval shopping center across from the SAQ
Centre Dentaire Les Jardins Dorval - Dorval, Quebec | Net+ACDQ
While their website says they are on Dorval avenue the easiest entrance is on Carson st.
