Teeth grinding is one of the causes of sensitive teeth. It’s one we look for closely at our office in Everett, because most people don’t realize they do it. Grinding and clenching put heavy, repeated force on your teeth, and over time that wears down the enamel and exposes the softer dentin underneath.
So here’s how grinding leads to sensitivity, how to tell if you do it, and how to protect your teeth.
Can Teeth Grinding Make Your Teeth Sensitive?
Yes, in two ways. The obvious one is wear: grinding flattens and thins the enamel on the chewing surfaces until the dentin underneath starts to show through.
The second is quieter. The same force flexes the tooth at the gum line and can chip a small notch there, which exposes the sensitive root. Either way, you end up with exposed dentin that reacts to cold, air, and pressure.
How Do I Know If I Grind My Teeth?
Most people who grind do it in their sleep, so they never catch themselves. The tells usually show up elsewhere.
- A sore jaw or tired facial muscles in the morning
- Dull headaches that start around the temples
- Teeth that look flat, worn, or chipped at the edges
- A partner who hears the grinding at night
If a few of these sound familiar, grinding is worth raising at your next visit. We can often spot the wear pattern on your teeth before you’ve noticed it yourself.
How Do I Stop Grinding My Teeth?
You can’t always stop the grinding itself, especially in your sleep, but you can protect your teeth from it. A custom-fitted night guard is the standard way to do that. It cushions the teeth so the force lands on the guard instead of your enamel, and it’s worth asking your dentist about one.
Daytime clenching is more in your control. Notice when your jaw is tight, especially at a desk or in traffic, and let it relax. Managing stress helps too, since grinding often tracks with it.
How Is the Damage Repaired?
Once your teeth are protected, we can rebuild what the grinding wore down. Dental bonding restores worn edges and chewing surfaces, and heavier damage is restored with crowns.
The order matters here. We protect first, then repair, so the new work doesn’t get ground down the same way the enamel was.
When Should I See a Dentist?
Come in if your teeth are getting more sensitive, if you’re waking with jaw pain or headaches, or if you notice your teeth looking flatter or chipped. Grinding tends to progress quietly, and catching it early usually means a night guard and minor repairs instead of bigger ones later.
Frequently Asked Questions
Does grinding cause permanent tooth sensitivity?
Not usually, if you protect the teeth before the wear goes deep. The sensitivity from exposed dentin often eases once grinding is managed and the enamel is protected. Damage that’s already there can be repaired.
Can a night guard stop the sensitivity?
It can help a lot. A night guard doesn’t cure sensitivity on its own, but by stopping further wear it lets the teeth settle and prevents new dentin from being exposed.
Why is my jaw sore in the morning?
Morning jaw soreness is one of the most common signs of night-time grinding or clenching, since your jaw muscles have been working while you sleep.
Can grinding crack a tooth?
Yes. The repeated force can crack a tooth or a filling over time, which is another reason sensitivity from grinding is worth addressing early.
Does stress make teeth grinding worse?
Often, yes. Many people grind or clench more during stressful stretches, so managing stress is a real part of protecting your teeth.
The Bottom Line
Teeth grinding wears down enamel and notches the gum line, and the sensitivity that follows is often the first sign you notice. You can’t always stop the grinding, but a night guard protects the teeth, and bonding rebuilds what’s already worn once they’re protected. Catching it early at a regular visit is a core part of good preventive care.
