Review (5/5): Finally, an Affordable and Safe Teeth Whitener.
A friend recommended OH Oral Hygiene and I am very pleased they did.
Over the years, I've tried the expensive peroxide-based teeth whitener's my dentist recommended, but they are too strong and irritate my gums.
In addition, I've used the whitening strips, but I found those to be cumbersome and ineffective.
After only one week, I already see more whitening and less staining (from tea and red wine) without any trays or strips.
I hope you have the same results.
