I'm jealous of the white teeth.

Maybe because I didn't take good care of my teeth when I was young, I have eight gold teeth, so going to the dentist is the scariest thing for me. Maybe because I like coffee, my teeth are also yellow. I brush well and even use a water pick to clean between my teeth because I feel uncomfortable with food stuck there, but my teeth don't stay white, and I feel embarrassed sometimes. When I see celebrities smile, their teeth are white. How do they do whitening treatments?

Are you wondering about the cost, how many visits are needed, and if there is a way to manage it separately at home?
