The Daycare Resource Connection

Hi. My child is 7 now and he doesn't like brushing his teeth. I strictly direct him to brush his teeth twice daily. But he never brushes well and also doesn't have any care for his tooth. He always follows unhealthy diets. He eats a lot of chocolate and sugary snacks. Whenever I try to make him brush, he will start crying. I am fed up with my child's behavior. He goes to daycare. The caretakers are complaining me about his ugly teeth. Now I think his teeth started to decay and have a cavity in his right molars. When I shared this with one of my colleagues, she suggested to take him to a kids dentist in Oakville. I have heard that using mouthwash can help to prevent tooth decay and cavities. Will it help in my son's situation What will be the treatment procedures to remove cavity? Can a single visit solve his problem?
