Keep searching for a dentist that can help you & who will work with you for payment. If your family makes you feel badly about yourself, surround yourself with supportive friends.

If you are desperate to have dental implants, consult with dentists in your locality and talk to him/her regarding your financial problem. Also, check for a dental clinic in your locality who accepts insurance policy for all dental work.
I don't know the details but one of my friends who is considering dental implant services from Whitby ( http://www.appletondental.ca/services/dental-procedures/implants/ ) said that the dental clinic he had chosen will accept all insurance policies but the payment depends upon the terms of his policy. He had been to many dentists asking if they accept insurance policies or not. In most of the dental clinics, they don't give insurance for cosmetic dental services. So it's better to inquire before making a final decision.
