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

Our Mini Dental Implants Are The Solution!

They're Much Cheaper

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

They're Half The Size

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

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.

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.
