Oral Hygiene Product

I would like to barter my services for a complete dental makeover; I would like to be able to chew my food normally and be able to smile again. My teeth have always been prone to decaying easily no matter how much I brushed and flossed. I am a singel mom and my teenage daughters will both be out of the house in less than two years and I would like to start dating and be able to meet someone to begin a life with and I cannot do that being uncomfortable and insecure to smile.
