Go on a white-teeth diet
If you’re quaffing red wine, coffee or black tea, expect the results to show up as not-so-pearly whites. According to the American Dental Association, the dark pigments called chromogens attach to the your white tooth enamel, creating stains. The tar and nicotine in tobacco will also leave behind brownish stains on your teeth. Brushing immediately after eating or drinking foods that stain teeth can help. If you want to whiten your teeth, talk to your dentist about the best at-home and in-office methods.
Chuck your toothbrush…
…or change the head of your electric toothbrush at least every two to three months for healthy teeth. Otherwise, you’re just transferring bacteria to your mouth. According to Beverly Hills dentist Harold Katz, the best way to brush is by placing your toothbrush at a 45-degree angle against your gums and gently moving it in a circular motion, rather than a back-and-forth motion. Grip the toothbrush like a pencil so you won’t scrub too hard, and make sure to avoid these other toothbrushing mistakes.
