Q. Hi there,(Im 20) my teeth are really unsightly yellowly colour and kind of mottled stained looking. I’m not sure if this is due to flurosis (?) too much flouride or just bad dental hygiene from when I was younger and had braces. I regularly visit the dentist/hygienist every 6 months but they haven’t really mentioned anything about the colour and that my teeth are healthy and enamel is fine. Although I am a little embarrassed to mention it and what would I say!? Would cosmetic dentistry and what are the costs?? thanks,
