Question:

I used this whitening toothpaste months past the 4 weeks it says on the tube.?

how bad is that for your teeth?


Answers:

There are a few types of whiteners, but not all are safe. Some actually dissolve the top layer of enamel, making your teeth appear whiter since the lower layer has not yet been exposed to staining foods. However, this weakens your teeth/enamel. I'd check with your dentist before using a product, or stick with Crest whitening products. Their line is safe.
