No need to suffer mouth pain. Here's how to stop being so sensitive.

STEP 1: BRUSH BETTERTry an electric toothbrush designed for sensitive teeth. "The ones with small rotating heads are my favorite," says Nancy Rosen, DMD, a dentist in New York City. When it comes to toothpastes, those designed for sensitive teeth can help when used consistently over time.

STEP 2: EAT SMARTERRosen recommends waiting at least 30 minutes before brushing if you've been eating or drinking something with a high acid content. Choose sugarless gum or drink water after eating, and opt for a straw if you're drinking acidic beverages to decrease the exposure of your teeth to acid.

STEP 3: STICK WITH ITIf these steps aren't reducing sensitivity, try something stronger. Products like Crest Sensi-Stop Strips ($20, can help, offering relief for up to a month. "If OTC options still don't work, see your dentist," Rosen says. "You may need a filling, veneer, or crown."
