I've had a small yellow stain on my front tooth for about 5 years and I want to know how to easily and quickly clear it up and make sure it never comes back. My dentist says I can't use whitening strips until I'm 16 (I'm 13 now) and I also think he sai that the stain is something that has to do with my genes but I'm not sure if he said that or if my step mum who used to be a dental assistant said it... How can I remove it before the next school year? Home remedies would be the best, if there's anything my dentist can do that would be good to.

No, if it will not clean from normal brushing,

You could try adding a bit of baking soda to your toothpaste at each brushing. Not guaranteeing it will work, but it will not be harmful.

Take a advice from dentist , I think it's removed(clean), but take a care.
