Aquafresh vs. Rembrandt Whitening?

Question

Aquafresh Whitening Tray versus Rembrandt Whitening Strips.

1. Which works the best?

2. What's the cost of both?

3. Is the more expensive one worth pay more for?

I'm leaning toward the White Trays because I heard they keep the whitening stuff more concentrated on your teeth.

By the way, the cost is important. So if one is out of my price range, then I will probably just get the other one.

Answer 1

Neither, get it done by a dentist
