Dr. Mortensen did a filling replacement. Excellent work! Didn't feel any discomfort with the freezing or the filling replacement. The dental assistant was friendly and professional.

Came in for cleaning, hygienist hardly cleaned my teeth, I was asked to rinse every 2-3 minutes. Polishing took less than a minute...

Keep 28 Dental Centre replied:

we are so sorry you felt this way. Please call our office so we may fix the situation.

Great processional service with a personalized approach. I have been a patient for over 20 years.

If I could give more than 5 stars I would! I am probably the worst person in a dentist chair being filled with fear and anxiety yet somehow the wonderful staff at Keep28 make my visit enjoyable. Keri at front reception is amazing and friendly, Mia my hygienist is funny and sweet and extremely gentle and Neal does everything in his power to make me feel comfortable (as does Frances). If you have ANY hesitation about going to a dentist, please check out Keep28. They truly care about their patients.

A painless and pleasant experience

5 stars Customer since 1991

Going to the dentist is not an uncomfortable experience anymore since I have been coming to Keep 28, and Mia especially makes it as enjoyable as it can be considering it is still a dental visit.

5 stars Customer since 1994

As always, my experience with Keep 28 Dental Centre is excellent. My appointments are on time, which is truly appreciated. The staff are friendly, efficient, and always greet me by name. My dentist, Dr. Mortenson, and Mia, my hygienist, make me feel very comfortable and thoroughly explain the procedure. They ask pertinent questions about my overall health, change in medications, and any problems I might have with my teeth.

I am a long time patient at Keep 28. Before I started there, I was always afraid to go to a dentist because my teeth are extremely sensitive and I always experienced pain when I visited. Since joining Keep 28, that fear and pain is gone due to the way I have been treated, both professionally and personally. They treat me with respect, kindness and understanding. That goes a long way in making each appointment anxiety-free and enjoyable.

I highly recommend Keep 28!
