Not very inclusion oriented about dental options other than their own. Not helpful when requesting copies of xrays sent to a dentist you are obtaining a "second" opinion from. Office environment is not very professional. Advice; don't use up your dental insurance allotment for the year at this place. Constant turnover rate of Dentists here is big clue.

Terrible experience. My family and I will never come back to this Office. Unorganized and under equipped to handle my family needs. Poor Service unfriendly staff. No concerns for patients needs or time.

My mother had to bring my children in for their appt as I was stuck at work. Someone was supposed to call me with the details of the appt as well as ortho recommendations and or concerns and no one has followed up

Dr. Jack and his team at Assure Dental of Ontario are AWESOME and AMAZING. The level of care we receive here is always EXCELLENT. We stayed away from the dentist for years due to bad experiences elsewhere. So if you're like we were just hoping and praying this time would be different...look no further - DR. JACK and ASSURE DENTAL OF ONTARIO are our DENTAL CARE TEAM FOR LIFE!

Up until it was time to remove my braces, I was VERY happy with Assure Dental. Then there was a billing issue and I was charged an additional amount to have them removed with the understanding that my insurances would be billed again and I would be reimbursed.

After more than a year of trying to get answers and reimbursement (or even a return call), I have called it a loss. The actual dental care is wonderful! But the billing department is subpar and I have taken continued care for me and my family elsewhere.
