I have dipped a total of around 6 times and I have braces and I want to know if my dentist will know?

I don't want my parents to find out and it has been SKOAL mint about 3 and Copenhagen natural, both are long cut, I know the dangers of chewing tobacco so don't give me a speech but if I stop now will my dentist/orthodontist know when I go into their office? I do not floss and I do brush my teeth and I use mouth wash a lot. PLEASE RESOND ASAP with REAL information!
