A. You can have your teeth whitened using bleach. This works very well on normal discoloration. The home whitening kits with custom made trays work the best. These are only available from dentists. The products that you buy over the counter or receive from beauty therapists are either not strong enough or can be harmful. There is no guarantee that your teeth will go to the shade that you want but they will definitely get whiter. The only exceptions to this are if your teeth have tetracycline staining and fluorosis. Whitening doesn’t work as well in these cases. If you have tried whitening before and don’t want to do it again then you could always investigate having veneers placed on your teeth so that they are the colour that you want

I hope this has helped
