Water picks, also known as oral water irrigators, aren’t for everyone. They work best if you have braces or other dental work that traps food. They don’t remove plaque; only brushing with toothpaste and flossing can do that.

Mouthwash can do more than simply freshen your breath -- it can ward off gum disease. But that’s only if you use a bacteria-fighting rinse. A product with fluoride can help prevent tooth decay. Rinsing with an alcohol-based mouthwash isn’t good for children under 6, who are likely to swallow the liquid. Ask your dentist which type is best for you.
