RDC is by far, the BEST place for all your dental needs. Dr. Peter Riordan is a compassionate dentist who really takes pride in his work and cares for his patients as if they were family. His staff is top notch and will do everything to accommodate the patients. Julie and Sarah are beyond amazing and Audrey and Amy are beyond fantastic! As a patient who has high dental needs, Dr. Riordan and his staff are always there to calm me and help in any way they can even if it’s after hours. Thank you for all you do RDC!

The entire team at RDC is fantastic! Friendly, responsive and thorough. My first visit was in 2018, where Dr. Riordan quickly determined that I needed tooth restoration in the form of crowns. My teeth now look fabulous and I have received many compliments! After seeing various dentists in Toronto without any suggestions of restoration, I feel grateful to have found a dentist that was concerned about the health of my teeth and their appearance.

I always have an incredible experience at RDC Dental, I've been going there since I was a child and now I bring my autistic son there. We have always been treated exceptionally well and they are incredible with my difficult child. I highly recommend them to family and friends.

Dr Riordan and his team are stellar:) My husband needed full mouth reconstruction. We had "shopped around" everywhere from Mexico to Costa Rica..lol and 4 dentists here but the $50,000 price tag was more than our wallet could handle. After exhausting research the internet led us to Dr Riordan and we couldn't be more pleased with both the savings and the workmanship. My husband has soooo many compliments. He told the Dr. he wasn't concerned about being in any toothpaste commercials...but he could be now...Thanks Dr Riordan and team:)

Mini Dental Implants Oshawa ON Dentist
Do You Have Missing Teeth? Loose Dentures?

Our Mini Dental Implants Are The Solution!

When compared to traditional dental implants, mini dental implants (MDIs) are cheaper, last longer and can be completed in just one visit!

They're Much Cheaper

In most cases, mini dental implants and the associated procedures cost 50% - 66% less than traditional dental implants.

They Heal Quicker

It's a less invasive procedure that results in faster healing times, virtually no discomfort, and less visits to the dental office.

They Save Bone Structure

When you have missing teeth, you've probably lost some bone structure in your jaw. Mini dental implants will stop the bone loss.

They're Half The Size

Mini dental implants are about half the size of traditional implants, and therefore don’t require extensive, painful surgery.

Titanium Means No Decay

Being made out of titanium, mini dental implants are not subject to periodontal disease or decay and will last for years.

Results Are Immediate

With mini implants, you can forget about waiting months - or even longer in some cases - and get yours almost immediately.
