Do over the Counter Whiteners Work?
Yes, but they take a while. They are about a fourth to a half as strong as professional whitening. With the constant cycle of tooth staining while trying to whiten with a lower strength, it’s hard to see a drastic improvement in over the counter whitening. I recommend a dental visit before trying to whiten. What many people do not consider is that, if tooth colored fillings are present; these filling do not bleach like the teeth do.
