hello Dr safeer how are you sir?

sir i had a brown/Yellowish front upper incisor tooth ( i think its because of antibiotics) i tired a lot of tooth paste but no luck.
its basically an intrinsic stain.
is it possible to remove this stain with a tooth whitening process or not? as i am completely upset now about my teeth because i am only 21 years of age and i cannot even smile properly. so what would you suggest for me sir? please reply to me through my email address. yours sincerely.
