Teeth Grinding

Written by: Becki Murray

Last Updated: 11 November 2024

Are you waking up in the morning with a tight, sore and clicking jaw that feels like you’ve been chewing hard gum all night? You’re probably struggling with teeth grinding – and you aren’t alone.

Teeth grinding is actually predicted to affect up to 10% of us at some point in our lives, especially during periods of high stress or due to teeth misalignment. However, the symptoms can range in severity.

Read on to discover what teeth grinding is, the main causes and treatments (including our tried-and-tested recommendations) – and why you really shouldn’t just grin and bear it…

What is teeth grinding?

Teeth grinding – or bruxism, to give it its official name – is the clenching, grinding, or gnashing of your teeth. It is very common during sleep, which means you might not even notice you are doing it until you experience the unfortunate side effects. It can also occur when you are awake, particularly if you are feeling stressed and anxious.

What are the symptoms of teeth grinding?

The most immediately noticeable (and defining) symptom of teeth grinding is a tight, sore, and potentially clicking jaw, especially in the morning. But it can also have further-reaching consequences such as headaches, earache, neck and shoulder tension, and disrupted sleep.

In severe cases you may also end up with tooth damage, as the grinding can weaken, flatten, and even fracture your back teeth, while making them more sensitive.

Is there anything else that can make teeth grinding worse?

Aside from stress, other things that can make teeth grinding worse are lifestyle habits such as drinking too much caffeine or alcohol, especially just before bed. Your genes play a part as well, as bruxism tends to run in families. Certain medications may make teeth grinding more common too, especially those that affect the central nervous system. That includes antidepressants.

 

What causes teeth grinding?

Stress (both acute and chronic) is a major cause of teeth grinding as we tend to hold tension in our jaws during anxious moments, which can build up and worsen over time.

However, the condition can also indicate teeth or jaw misalignment – which can mean it’s a conversation to have with your dentist. In particular, when your teeth do not come together properly, you may subconsciously clench your teeth to move them to a more comfortable position. Teeth grinding may also be a sign of some sleep disorders that need investigation, such as sleep apnoea, as disordered breathing can lead to disruption sleep patterns.

What does teeth grinding feel like?

The team at TTG unfortunately know about teeth grinding far too well. You can read about Alice’s experience (and how she successfully treats it) here. Becki, our contributing editor, shares her experience below:

“I’ve probably been grinding my teeth for years, so much so that I can click my jaw almost at will. That’s due to the build-up of tension in the area, and I feel it most as a constant tightness and pain in my jaw particularly on the right-hand side of my mouth. It’s definitely related to stress for me and, in all likelihood, a contributing factor for my chronic headaches. Unfortunately, it’s a hard habit to break, especially as I do it subconsciously when sleeping, so I rely on several strategies (listed below) to help minimise the side effects.”

When should you see a dentist about teeth grinding?

If you suspect you are grinding your teeth it’s worth speaking to your dentist at your next appointment as this can help to prevent further tension and damage to your teeth and jaw. It’s advisable to do this before booking in for an aesthetic tweak! That’s because a dentist will be able to diagnosis any potential jaw or teeth misalignment, while also advising about more simple lifestyle strategies for its prevention and management, such as mouth guards and stress relief practices.

How can toxin injections help with teeth grinding?

You might have only ever thought of toxin injections as smoothing out wrinkles, but they are actually an increasingly popular (if not permanent) ‘fix’ for teeth grinding too. That makes sense when you consider how toxin works – by temporarily paralysing the muscles under your skin to limit expression lines from facial movement or in this case weakening your bite strength. This means it can help relax your jaw muscles, eliminating tension that has built up, while also reducing the intensity of your grinding to help protect your teeth. When used in this way the injections are called ‘masseter toxin’ injections.

The results can last up to four months – the jaw muscles are strong! – so you do need to commit to repeat treatments to see results and most people will also still wear some sort of nightly mouthguard to protect their teeth. Importantly, these injections (as with all tweaks!) should be administered by a qualified and trusted practitioner who knows how to correctly use them for bruxism. After all, while it’s a clinically-proven treatment and widely available, it is still an off-label use for toxin.

Alice has been having toxin injections for her teeth grinding with Dr Sophie Shotter for several years. You can read all about her experience of the treatment, including whether it hurts and how quickly you can see results.

What other treatments are available for teeth grinding?

Stress management techniques

The first solution to try for teeth grinding is to reduce your stress levels and address any underlying anxieties that could be triggering the condition – although this can feel easier said than done! Some good things to try include relaxation and breathing exercises before going to sleep; keeping technology, including your phone, out of your bedroom to help your mind unwind; meditative activities such as yoga in the evening; and avoiding caffeine and alcohol pre-bed.

Mouthguards

Wearing a mouthguard at night to protect your teeth can be especially helpful if you are experiencing (or are worried about) tooth damage from grinding. The nightguards are worn during sleep to form a physical barrier between your upper and lower teeth, which prevents them being able to crunch against each other. They can take a little getting used to at first, but you can buy them yourself, or get one fitted by your dentist for the most comfortable, personalised fit.

Dental realignment

For underlying dental issues, such as misaligned teeth, the best course of action is dental treatment via an accredited dentist or orthodontist. This may involve orthodontic procedures such as braces, or teeth restorations – which can all be discussed during your appointment. Improving alignment in this way can reduce the strain on your jaw muscles, decreasing your risk of teeth grinding, while also improving overall jaw and teeth appearance should that also be something you want.

Acupuncture

Facial acupuncture may also prove valuable for reducing the side effects of grinding, by targeting the tension it can cause (although it won’t stop you doing it in the first place). Specially placed acupuncture needles can be used along the jawline itself to clear muscle knots in the area, as well as around the temples and forehead to target related tension headaches if you struggle with them.

Cognitive therapy

If you are struggling with chronic anxiety which is contributing to your teeth grinding, cognitive behavioural therapy (CBT) may be the most effective treatment to try. This type of therapy helps you identify and modify the behaviours or feelings that are leading to grinding, so you can develop healthier coping mechanisms, leading to broader health benefits.

Medication

Medication is available that could help with grinding but there are often drawbacks to taking this approach. When you have tried all other options without much success, you may be prescribed muscle relaxants to ease tension in your face, although these do come with side effects. Equally, antidepressants may help the underlying anxieties causing your bruxism, but may also contribute towards the behaviour in some individuals.
