Does any one know if whitening strips work?

Question

Thinking of buying them.

Answer 1

yes they work but if u use them too much or too often your teeth will look clear starting around the edges from whitening too much

Answer 2

To some degree. They simply keep peroxide localized to the tooth area to whiten them. It can also break down your enamel however, so it is not advisable. Simply brush you teeth after meals and avoid coffee and smoking.  

Answer 3

They definetaly work.

Answer 4

They work indeed, i used them (crest classic) and my teeth are white and beautiful, HOWEVER, now the enamel on the inside mouth (back of my teeth) has been eaten so badly that in between my teeth and around my gum line has turned black... Beware.

Answer 5

Yes they do. But sometimes they make your teeth really sensitive if u use them a lot bc your enamel starts to go away.
