Any portion of the fee that is not reimbursed can be claimed as a medical expense.
Most non-cosmetic dental expenses are tax deductible.
The Medical Expense Tax Credit (METC) is a non-refundable tax credit that you can use to reduce the tax that you paid or may have to pay. You can claim eligible dental expenses paid in any 12-month period ending in the fiscal year in question and which have not been claimed by you or by anyone else in the previous year.
If you paid for dental work, you may be able to claim them as eligible medical expenses on your income tax and benefit return (T1), including:
Dental care Dentures and Implants
Generally, you can claim all amounts paid, even if they were not paid in Canada, and only the amount for which you have not been, or will not be, reimbursed.
Orthodontic work qualifies as a dental expense, so you can include the costs when you figure your medical-expenses deduction on your annual income taxes. Deduct the costs in the year that you pay for the costs, even if you receive the dental treatment in a different year
