I have the intention of becoming a dentist. I am worried about if a man needs to have a gold tooth for health or for fashion reasons. What should i do? Should i just put it in because it is their choice, or should i somehow say that i can’t put them in? I don’t know…. Help please

My guidance counselor told me to go to a dental hygiene school first then move to a school that has a dentistry course, do i have to major in something first, i m kind of confused but so far ive applieed to schools that offer dental hygiene, then i am planning on continuing school and becoming a dentist
