I have really yellow teeth (do crest whitestripes really work?!

I would recommend you try a whitting tooth paste first!. Such as those containing baking soda and peroxide!. Also, if you do, it would be a good idea to cutback any coffee, tea, sodas or smoking!. These can all cause yellowing of the teeth!.

Also certain drugs like tetracycline, can cause yellowing or spotting of teeth in young people if they or their mothers(prior to birth or breast feeding) use it!.

In regards to over the counter and dental whitening products, prolonged bleaching can lead to severe irritation in the teeth and gums!. Teeth whitening products make use of chemicals like Hydrogen Peroxide that need to be used in the right concentration and right quantities to have the desired effects!. People who use tooth whitening products at home do not pay much attention to their correct usage!. If done properly teeth whitening is harmless!. It is only when people buy teeth whitening products over the counter and use them without following the proper directions that it is dangerous!.

Large amounts of Hydrogen peroxide can cause irritation to the delicate and soft tissues in your mouth!. When teeth bleaching is done in a dentist
