Answer from Dr Keith Cohen about whether teeth whitening can be damaging

Question: I want to whiten my teeth, but is it true this can be damaging?

Answer: According to Dr Keith Cohen of Dentexcel, there is no evidence that teeth whitening can cause damage. “If you have receding or sensitive hums, it can be a little painful, but there are no real adverse effects,” he says. Go to a reputable dentist and don’t buy prescription whitening kits over the internet. Professional whitening should last for a couple of years; use whitening toothpaste to help maintain your gleaming teeth.
