Your Toothbrush

Because toothbrushes come in all sorts of shapes and sizes, it's important for you to choose one that fits the contour and size of your mouth. For most people, a 4 or 5-rowed, soft, nylon-bristled toothbrush will do, but extra features can be helpful. For example, an extended tip helps reach back molars and the inside of your front teeth. Brushes with higher bristles in the center are better at reaching below the gum line. The rubber tip at the end of some brush handles is good for massaging the gums after brushing and flossing.

At the first sign of wear, you should replace your toothbrush. At the very least, you should replace it every three months. It is also important to replace your toothbrush after you’ve had a cold, since the bristles have germs that can lead to getting sick all over again. Electric toothbrushes are effective but not necessary. They are helpful for people who don’t have a good brushing technique and for those with a physical limitation that makes brushing difficult.

Toothpastes

Toothpastes deliver fluoride to the teeth and slightly under the gum line to protect against decay, whiten and remove stains from teeth, and encourage brushing by tasting good and preventing bad breath. Tartar control toothpastes do indeed reduce tartar, but only above the gum line. Avoid highly abrasive toothpastes, which can add to gum damage.
