Bad habits are hard to break but when it comes to teeth, here are six you should consider leaving behind.

1) NAIL BITING

The problem: nail biting can chip and wear teeth.

The solution: identify triggers, reduce stress, try to find something to keep your fingers busy, commit to stop.

2) BRUSHING TOO HARD

The problem: brushing too hard can irritate gums and damage teeth through abrasion

The solution: brushing for two minutes twice a day is best — use a soft toothbrush and don’t apply too much pressure.

3) GRINDING

The problem: grinding can cause chipped or cracked teeth in addition to joint pain and muscle pain.

The solution: a mouthguard for nighttime, relaxation exercises.

4) CHEWING ICE CUBES

The problem: broken or chipped teeth.

The solution: just say no.

5) CONSTANT SNACKING

The problem: snacking all day — especially on sugary foods — puts you at higher risk for cavities.

The solution: if you need to snack, try to stay away from sugar. And follow the snack with a glass of water to rinse away leftover food.

6) USING YOUR TEETH AS TOOLS

The problem: using your teeth as scissors, pliers, etc. which can chip, break, or wear teeth.

The solution: take the time to get the right tool –– not your teeth –– to get the job done.
