Many people grind or clench their teeth without even realizing it — often during sleep or moments of stress. A little occasional grinding is harmless, but persistent grinding (known as bruxism) puts real force on your teeth over time and is a leading cause of cracked and worn teeth. Here’s what to look for and when it’s time to act.
Signs You May Be Grinding Your Teeth
- Waking up with a sore jaw, face, or dull headache
- Teeth that look flattened, chipped, or worn down
- Increased tooth sensitivity
- A partner who notices grinding sounds at night
- Tight or tired jaw muscles during the day
How Grinding Leads to Cracked Teeth
Your teeth are strong, but the repeated pressure of grinding — which can far exceed normal chewing force — creates tiny stress fractures that grow over time. Eventually a tooth can crack, sometimes below the gum line where you can’t see it. A cracked tooth may cause sharp pain when biting, sensitivity to temperature, or come with no warning at all until it worsens.
When It Becomes an Emergency
A cracked tooth that’s causing severe pain, a piece that has broken off, or signs of infection all warrant prompt attention. The sooner a cracked tooth is treated, the better the chance of saving it with a filling, crown, or other repair rather than losing it.
Protecting Your Teeth
The most common solution is a custom night guard, which cushions your teeth and absorbs the force of grinding while you sleep. Managing stress, cutting back on caffeine and alcohol, and being conscious of daytime clenching also help. A dentist can assess the wear on your teeth and recommend the right approach.
Frequently Asked Questions
Can grinding really crack a tooth? Yes. The sustained force of grinding weakens teeth over time and is a common cause of cracks, chips, and wear.
Does a night guard from the drugstore work as well as a custom one? Custom night guards fit better, last longer, and are more comfortable, which means you’re more likely to actually wear it, making it far more effective.
How do I know if I have a cracked tooth? Sharp pain when biting, lingering temperature sensitivity, or discomfort that comes and goes can all signal a crack. A dental exam confirms it.
