How to Stop Grinding Your Teeth: Treatments That Actually Work

Editorially reviewed by the Dental.me Editorial Team · Updated July 2026

If you wake up with a sore jaw, a dull headache, or teeth that feel sensitive for no obvious reason, there is a good chance you are grinding your teeth. It is one of the most common dental problems dentists see, and most people who do it have no idea until the damage starts to show. The good news: teeth grinding is very treatable. This guide walks through what grinding actually is, how to recognize it, why it matters, and the treatments that genuinely work — starting with the steps you can take right now.

What Is Teeth Grinding (Bruxism)?

The medical term for grinding or clenching your teeth is bruxism. It comes in two forms. Sleep bruxism happens at night, is completely unconscious, and is often the more destructive of the two because the forces involved can be far higher than anything you would apply while awake. Awake bruxism tends to be clenching rather than grinding, and is usually tied to concentration or stress — think of the jaw you set while stuck in traffic or deep in a spreadsheet.

Because sleep grinding happens while you are unconscious, most people never catch themselves doing it. Instead, they notice the aftermath: worn teeth, jaw fatigue, or a partner nudging them awake because of the sound. For a deeper look at the condition itself, our overview of teeth grinding and bruxism covers the mechanics in more detail.

Signs You Grind Your Teeth

Since grinding is usually silent and unconscious, the clues show up in your mouth and your mornings. Watch for these common signs:

• Worn, flattened, or chipped teeth — often the first thing a dentist spots at a checkup.
• Jaw soreness or tightness, especially first thing in the morning.
• Dull morning headaches that start around the temples.
• Tooth sensitivity as enamel wears thin and exposes the layer beneath.
• Scalloped indentations along the edges of your tongue or a ridge of tissue along the inside of your cheek.
• A partner hearing a grinding sound at night.
• Cracked teeth or fillings and crowns that keep failing under repeated pressure.

If your teeth have become sensitive, our guide to tooth sensitivity explains how enamel wear translates into that sharp, fleeting ache — and what helps.

Why Grinding Your Teeth Matters

Grinding is easy to shrug off until it costs you. Over months and years, the constant pressure wears enamel down, flattens the biting surfaces, and can fracture teeth or split existing dental work. Once enamel is gone it does not grow back, so repairs mean fillings, crowns, or worse. Grinding also strains the temporomandibular joint that connects your jaw to your skull, which can lead to clicking, pain, and limited movement. Our explainer on what TMJ is covers that connection. Add in the recurring headaches and disrupted sleep, and a habit that feels minor becomes a real drain on your comfort and your wallet.

What Causes Teeth Grinding?

There is rarely a single cause, but a handful of triggers show up again and again:

• Stress and anxiety — the most common driver, especially for daytime clenching and stress-linked night grinding.
• Sleep apnea and disrupted breathing — grinding is strongly linked to interrupted sleep, and treating the breathing problem often calms the grinding.
• Caffeine, alcohol, and nicotine — all can increase grinding, particularly in the hours before bed.
• Certain medications — some antidepressants, including SSRIs, list grinding as a possible side effect.
• Bite problems — teeth that do not meet evenly can contribute in some people.
• Age — grinding is common in children, who very often outgrow it as their adult teeth and jaws mature.

Treatments That Actually Work

Here is where most people want to start. The right plan usually combines protecting your teeth with tackling whatever is driving the grinding.

A Custom Night Guard (Occlusal Splint)

This is the front-line defense. A night guard is a slim custom appliance that fits over your teeth and absorbs the force of grinding so your enamel does not. A guard does not stop the grinding reflex itself, but it protects your teeth from the damage while you address the underlying cause. A dentist-made guard is worth the cost over a drugstore version: it is molded to your exact bite, fits securely, is far more comfortable, and lasts much longer. Cheap boil-and-bite guards are often bulky, work loose overnight, and wear through quickly. See our breakdown of how much a night guard costs to weigh your options. (Note that a grinding night guard is different from a sports mouthguard, which is built for impact, not clenching.)

Manage Stress and Retrain the Habit

Since stress is the leading trigger, this is often where the real progress happens. Regular exercise, relaxation techniques, and better sleep habits all help. Cognitive behavioral therapy (CBT) can be effective for stress-driven grinding. During the day, practice awareness: your teeth should only touch when you chew or swallow, so if you catch them clenched, relax your jaw and rest your tongue on the roof of your mouth with your lips together and teeth slightly apart.

Address Sleep Apnea

If your grinding comes with loud snoring, gasping, or daytime exhaustion, ask about a sleep evaluation. Treating sleep apnea — with a CPAP machine or a dental sleep appliance — often reduces the grinding that rides along with it.

Cut the Chemical Triggers

Reducing caffeine, alcohol, and nicotine, particularly in the evening, can meaningfully lower nighttime grinding. If you suspect a medication is the culprit, talk to the prescribing doctor rather than stopping it on your own.

Jaw Relaxation and Physical Care

Gentle jaw stretches, a warm compress on the muscles before bed, and self-massage can ease tension and soreness. These do not cure grinding, but they help the muscles recover and reduce morning pain.

Fixing the Bite or Dental Work

If uneven teeth or failing restorations are contributing, a dentist may recommend adjusting the bite, replacing worn fillings, or in some cases orthodontic treatment.

Botox for Severe Cases

For persistent, severe grinding that has not responded to other measures, small injections of botulinum toxin into the jaw muscles can reduce their clenching strength. It is not a first step, but it is a real option some dentists offer for stubborn cases.

Managing Symptoms Day to Day

While your treatment plan takes hold, you can ease the discomfort: use a desensitizing toothpaste if your teeth are tender, apply warm compresses to a sore jaw, stay well hydrated, avoid chewing gum or hard foods that overwork the muscles, and keep an eye on when you clench so you can consciously relax. Small habit changes add up.

When to See a Dentist or Doctor

Book a visit if you notice worn, chipped, or sensitive teeth, ongoing jaw pain, frequent morning headaches, or your partner hears you grinding. A dentist can measure the wear, fit a custom guard, and check for bite or joint problems. If grinding comes with snoring or breathing pauses in sleep, see a doctor about a sleep assessment, because the two are often connected. Early action keeps a manageable habit from turning into expensive repairs.

Teeth Grinding in Children

Grinding is very common in kids and usually harmless — most outgrow it as their permanent teeth come in. Mention it at routine dental visits so your dentist can watch for wear, and flag it to your pediatrician if it comes with snoring, disrupted sleep, or daytime tiredness. Custom guards are rarely needed for young children whose mouths are still growing.

Grinding your teeth is common, but it is not something you simply have to live with. Protect your teeth with a custom guard, tackle the stress or sleep issues underneath it, and loop in a dentist early. Do those things and you can stop the damage and get your mornings back.
