Q&A: Special toothpaste for tender teeth?

Some of my teeth hurt when I brush, even though I have no cavities or gum disease. I’m considering one of those special toothpastes for sensitive teeth. Do they really work? —J.H., Westminster, Vt.

Yes. Such pain usually stems from gum recession, which exposes the sensitive roots. The special pastes contain chemicals that can block that pain. Since brushing too hard can increase the gum loss and sensitivity, use a soft-bristle brush and a gentle touch. And avoid whitening or stain-removing toothpastes, which can be more abrasive. If those steps don’t help after a couple of weeks, your dentist may treat the problem teeth with a fluoride gel, a varnish, or a bonding agent.
