7 Signs You Grind Your Teeth at Night (and What to Do)

Most people who grind their teeth do it in their sleep — which means they find out from a partner, a headache or a cracked tooth.
The signs
Morning headaches at the temples, sore jaw muscles, teeth that look flat or chipped, new sensitivity, scalloped tongue edges, receding gums near the gumline and a partner hearing grinding.
Why it matters
Grinding can generate several times normal chewing force, wearing enamel, cracking teeth and breaking dental work.
What helps
A custom night guard absorbs force and protects teeth. If you also have jaw pain, a TMJ evaluation helps find contributing factors like stress and sleep.
