Many everyday habits quietly damage your teeth — from chewing ice and nail biting to using your teeth as tools, brushing too hard, and skipping floss.
Over time these habits wear down enamel, chip teeth and irritate the gums, often without any warning signs until real damage has occurred.
In this guide we break down the ten most common culprits, explain exactly how each one harms your smile, and give you simple, practical swaps you can start today to protect your teeth for life.
A few small changes to your daily routine — plus regular check-ups — go a long way toward keeping your smile healthy, strong and bright.
