Botox for Bruxism: Does It Work? What You Need to Know

Grinding your teeth isn’t just an annoying habit—it can wreck your teeth, trigger migraines, and leave your jaw feeling like it went ten rounds in a boxing match. If you wake up with a sore face or notice your teeth wearing down, you’re probably dealing with bruxism. And if mouthguards and stress management haven’t cut it, there’s another option: Botox.

You might know Botox for smoothing wrinkles, but it also relaxes muscles. When injected into the jaw, it can help stop the unconscious grinding and clenching that lead to pain and long-term damage. Let’s break down how it works, what to expect, and whether it’s the right fit for you.

‍

Can Botox Be Used to Treat Bruxism?

Yes. Botox is an effective treatment for bruxism, reducing excessive jaw clenching and teeth grinding by relaxing the masseter muscle.

By weakening the overactive jaw muscle, Botox injections help prevent the tension and stress that lead to headaches, jaw pain, and damaged teeth. It’s particularly beneficial for those who experience nighttime grinding, as it works around the clock without requiring any effort or equipment like a mouthguard. The treatment is quick, non-invasive, and can provide relief for several months, making it a popular choice for people who haven’t found success with other bruxism treatments.

If you’ve tried mouthguards, stress management, even sleeping on a cloud of lavender-scented dreams and nothing works, Botox might be the next move. It relaxes the masseter muscle, reducing the force of grinding and preventing long-term damage to your teeth and jaw.

How Does Botulinum Toxin Work for Teeth Grinding?

Botox works by relaxing the jaw muscles, reducing grinding and tension while preserving normal jaw function.

By blocking nerve signals to the masseter muscle, masseter Botox injections prevent excessive contractions that lead to clenching and grinding. This helps relieve jaw pain, headaches, and even ear discomfort caused by constant muscle strain. Since the muscle no longer overworks itself, it gradually shrinks in size, which can also refine the jawline for those with hypertrophy from bruxism. The result? A more comfortable, pain-free jaw and better protection for your teeth.

‍

What Is the Procedure Like?

The procedure is fast, straightforward, and requires no downtime.

In just a few minutes, Botox injections are administered directly into the masseter muscle, targeting the over activity that causes grinding and clenching. There’s no need for anesthesia, and most patients describe the sensation as a mild pinch. Once done, you can go about your day as usual, with no recovery time needed. Results start to appear within a few days, with full effects settling in after about two weeks.

Here's how it's done:

• Consultation – Your dentist or practitioner will assess if Botox is right for you. They’ll check the severity of your bruxism, muscle activity, and any previous treatments you’ve tried.
• Marking the Injection Sites – The practitioner will identify the best points in your masseter muscle for maximum effectiveness.
• Injection Process – A few tiny injections go directly into the masseter muscle. You might feel a slight pinch, but the pain is minimal—no numbing needed.
• Time Taken – The entire procedure takes about 10–15 minutes.
• Immediate Aftercare – You can go back to normal activities right away. Avoid rubbing the area or lying down for a few hours to prevent the Botox from spreading to unintended areas.
• Results Timeline – You’ll start noticing the effects within a few days, with full results in about two weeks.

‍

When Is Botox Treatment for Bruxism Recommended?

Botox is a great option when other treatments aren’t working. If you’ve tried mouthguards, stress reduction, and physiotherapy but still wake up with jaw pain, tension headaches, or worn-down teeth, it’s worth considering.

It’s especially useful for people who grind their teeth at night without realizing it, those with severe jaw tension, or anyone whose bruxism is causing visible changes in their facial shape. If your jaw looks wider from constant clenching, Botox can help relax the muscle and restore balance.

‍

Advantages

• Reduces pain – Eases jaw tension, minimizes headaches, and helps with earaches caused by muscle strain.
• Protects your teeth – Prevents excessive wear, enamel damage, and cracks from constant grinding.
• Slimmer jawline – Chronic grinding can enlarge the jaw muscle, making the face appear wider. Botox softens and slims the lower face over time.
• Non-invasive – No surgery, no incisions, and no long recovery period.
• Better sleep quality – Reducing grinding can lead to deeper, more restful sleep without constant muscle tension.
• No more bulky mouthguards – No need to wear a mouthguard at night, which many people find uncomfortable.
• Prevents long-term TMJ issues – Can help lower the risk of developing severe temporomandibular joint disorders over time.

‍

Possible Side Effects

Like any treatment, Botox isn’t all sunshine and relief. Some possible side effects of Botox are:

• Temporary soreness at the injection site.
• In very rare cases, mild asymmetry if the injections aren’t balanced perfectly.
• Effects wear off, so you’ll need repeat treatments, approximately annually.

‍

How Long Do Results Last?

Masseter muscle Botox typically lasts between 10 to 18 months. However, this varies depending on muscle strength, metabolism, and lifestyle factors. Over time, as the effects wear off, jaw tension and grinding may gradually return. This is why regular Botox treatments are recommended to maintain long-term relief and prevent symptoms from coming back.

With consistent treatments, some patients find that their masseter muscles weaken slightly over time, leading to longer-lasting results. Your practitioner will assess how often you need touch-ups based on your muscle activity and response to treatment.

‍

Who Should Skip This Treatment?

Not everyone’s a match for Botox, and in some cases, it’s best to explore other options. You should avoid Botox for bruxism if:

• You’re pregnant or breastfeeding – There’s not enough research on the safety of Botox during pregnancy or while nursing, so it’s best to wait.
• You have a neuromuscular disorder – Conditions like myasthenia gravis or ALS can make Botox risky, as it affects muscle function.
• You’re allergic to botulinum toxin – Although rare, allergic reactions can happen, so a full medical history check is crucial before treatment.
• You’re looking for a permanent fix – Although there is not permanent fit for bruxism, the management with Botox isn’t a one-time solution either. Regular Botox treatments are needed to maintain results, as the effects wear off after a few months.
• You have unrealistic expectations – If you expect Botox to completely stop grinding or cure the underlying causes of bruxism, it may not be the right treatment for you. It helps reduce symptoms but doesn’t eliminate the habit altogether.

‍

Are There Any Alternative Treatments?

Yes. If Botox isn’t your thing, you’ve got options:

• Mouthguards – Helps protect teeth by acting as a barrier, but doesn’t stop the grinding itself. They work best for preventing damage rather than addressing the root cause.
• Stress reduction – Since stress and anxiety are common triggers for bruxism, techniques like meditation, deep breathing exercises, or even cognitive behavioral therapy (CBT) can help.
• Physiotherapy – Jaw exercises, massage therapy, and posture correction can help release muscle tension and improve jaw alignment, reducing clenching.
• Medications – Muscle relaxants, anti-anxiety meds, or certain antidepressants may be prescribed in severe cases to ease jaw tension and reduce grinding.
• Acupuncture – Some people find relief through acupuncture, which aims to relax the jaw muscles and address any underlying imbalances causing the grinding.
• Dietary Adjustments – Avoiding caffeine, alcohol, and chewing gum can help minimize the intensity of teeth grinding.

‍

Where Can I Get This Type of Botox? Who Can Administer It?

This kind of Botox should only be administered by trained medical professionals. The best places to get this treatment include:

• Dental Clinics – Many dentists, especially those specializing in restorative dentistry or TMJ-related treatments, offer Botox for bruxism.

FAQs

What Are Some Bruxism Symptoms?

Bruxism symptoms can vary from mild to severe and often go unnoticed until complications arise. However, they can greatly impact your body and oral health. Common signs include:

• Jaw pain or tightness – A sore, tense jaw, especially in the morning or after stressful situations.
• Headaches – Tension headaches or migraines, often caused by excessive clenching.
• Tooth damage – Worn-down enamel, chipped teeth, or increased tooth sensitivity.
• Ear pain or ringing – Bruxism can lead to pressure in the jaw joint, leading to ear discomfort or tinnitus.
• Facial pain – Muscle fatigue and soreness in the cheeks and temples.
• Sleep disturbances – Partners may notice loud grinding sounds at night, disrupting sleep.
• Enlarged jaw muscles – Overactive masseter muscles can cause facial widening or hypertrophy.

If you experience these symptoms regularly, it may be time to seek treatment to prevent long-term damage and discomfort.

‍

Does Botox Really Work for Bruxism?

Yes. Botox reduces the strength of the jaw muscle, helping to stop excessive grinding while still allowing normal chewing.

By targeting the masseter muscle—the primary muscle responsible for clenching—Botox limits its ability to contract with full force. This prevents the cycle of tension and grinding that leads to pain, jaw fatigue, and worn-down teeth. The best part? It works subtly, so you can still eat, talk, and move your jaw naturally, just without the damaging pressure.

‍

Can You Get It on the NHS?

No, it’s highly unlikely. The NHS typically only covers Botox for medical conditions that are considered essential, such as chronic migraines or severe muscle spasms. Bruxism, while painful and damaging, is classified as a non-essential condition. This means most people will need to seek private treatment if they want to try Botox for jaw clenching and teeth grinding.

‍

Does It Hurt?

Not much at all. The needles are tiny, and most people say it feels like a small pinch or mosquito bite. If you're extra sensitive, a numbing cream can be applied beforehand, but for most, it's over before they even realise it.

‍

What Is Masseter Botox Treatment?

Masseter Botox is a targeted treatment where Botox is injected into the masseter muscle to reduce jaw clenching and teeth grinding. Botox masseter injections help relieve tension, prevents excessive wear on teeth, and can also slim down the lower face over time by reducing muscle bulk from overuse.

‍

Will Botox for Jaw Clenching Alter My Face?

Yes, Botox can change your face shape by slimming the jawline if your masseter muscles are overdeveloped from constant grinding. Over time, as the muscle relaxes and shrinks slightly, the lower face may appear softer and more contoured. However, the results are gradual and natural-looking, so you won’t wake up one day looking completely different.

‍

How Many Units of Botox Are Used for Bruxism?

The number of Botox units needed for bruxism depends on the size and strength of your masseter muscle. Most people require between 20–50 units per side, but those with stronger jaw muscles may need up to 60 units. Your practitioner will assess your muscle activity and customize the dosage to ensure effective results while maintaining natural movement.
