Figuring you’re over the age of 13, you have just this one set of teeth. So take care of them by brushing twice daily with an electric brush. Studies show that electric brushes reduce plaque much better than manual toothbrushes and also reduce the signs of gingivitis, thanks to the higher-frequency vibration that electric brushes provide while still being kinder to gum tissue than regular brushes. That said, you get what you pay for: Dentists warn not to cheap out with knockoff electric models, which provide only a motorized back-and-forth mechanical motion rather than what you really want, which is a rotating-oscillating motion or sonic vibration. Make sure to hold it so that the bristles touch the teeth and gums at a 45 degree angle. Doing so enables you to get the pocket on the edge of the gum tissue that’s the most critical area to keep clean.
