1. You Forget to Brush Your Tongue, Too

There's just as much gunk on your tongue as there is on your teeth. That's why you can't forget to brush your tongue. It'll reduce your bad breath and make you feel a whole lot cleaner.

2. You’re Brushing Too Hard

Don't hurt yourself. Brushing harder isn't going to do anything, except damage your tooth enamel and hurt your gums.

3. You Brush at the Wrong Angle

You should be holding your brush at a 45 degree angle. Then you should brush in super small strokes, almost like you're cleaning one tooth at a time.

4. You Replace Your Toothbrush Every Time You Get Sick

This is just a waste of money. Why? Well, "whatever germs are on your brush are the same ones your body just built up a bunch of antibodies against."

5. You Share a Toothbrush

You can share everything else with your man, but don't share your toothbrush. It could actually cause an infection.

6. Your Toothbrush is Too Old

The longer you use the same toothbrush, the worse the bristles will be. That means they won't clean your teeth as well. You should be replacing your brush every three or four months.

7. You Don’t Brush for Long Enough

You're meant to brush for two minutes straight. Grab your phone, set a timer, and don't stop until it goes off.

Have you been brushing your teeth wrong?
