A few years ago I was eating a Twix, when one of my teeth completely disintegrated. I was upset and embarrassed. I didn’t understand how I had gone from never having a filling, to bits of broken tooth crumbling into my hand.
When my dentist suggested I was grinding my teeth, she was being tactful; I was pulverising them.
Recently it was reported that one in 10 people in the UK grind their teeth, while other research suggests it’s between 15–20%, but the true figure is likely to be higher since studies rely on self-reporting, and often people will not be aware that they grind their teeth until a dentist or a partner tells them.
Some dentists believe that teeth grinding – or bruxism – helps generate saliva and fight tooth decay. It could also be due to existing dental issues, or a sleep disorder. One recent study suggested it might actually be part of cognitive function; a sign that we are literally chewing things over.
Ultimately, experts don’t know exactly why we do it, but they tend to agree on one thing: it is often caused, and exacerbated, by stress. Dr Ahmed Hussain, an associate dentist at Harrow-on-the-Hill Dental and Implant Practice, says: “I have teenagers complaining of jaw pain because they’ve got an exam coming up, or it could be adults going through a difficult time, a divorce.”
Psychotherapist, Natasha Crowe, compares it to other, more familiar physical manifestations of mental health issues such as tension headaches and IBS: “The body gives us signals that we’re under stress, but we tend to ignore them.”
In Olive’s case, her teeth grinding had gone undetected for some time: “I had no idea I was doing it until my dentist told me that my back teeth were cracking with hairline fractures.”
Dr Ahmed says cases where tooth breakage suddenly appears are not uncommon: “You look at someone’s teeth and they don’t have any fillings, so it’s nothing to do with what they’re eating or their oral hygiene.” Sometimes, the grinding is so bad that he can tell before he even examines closely: “The edge of their teeth is dead straight, and that’s not natural to see.”
Good teeth are often a sign that we are taking care of ourselves, and it can be distressing to face unexpected dental work. The dream where all your teeth fall out is much scarier when the very act of going to sleep makes the nightmare a potential reality.
Dr Ahmed treats around two patients a week for bruxism, and often this is accompanied by chronic headaches, insomnia, and jaw pain. He recalls a patient who “when her jaw locked, went into panic mode and couldn’t unlock it”.
There are also those who clench their jaws during the day, which Dr Simon Stern, a specialist periodontist and implant dentist at The Perio Centre on Harley Street, calls “awake bruxism”. “It doesn’t need to just be the dynamic movement,” he says. “It can be static – sitting there, clenching the muscles in your head.”
In these cases, jaw and breathing exercises, warm compresses, and anti-inflammatory medication, can help to reduce pain and tension. But what about when we’re asleep?
“When it’s a subconscious thing at night time, it’s almost like you’ve got no control over it,” says Natasha Crowe. This is where the most common treatment for teeth grinding comes in: the dreaded mouthguard. Bruxism sufferer Jade admits: “I would wake up to find I’d spat it out or thrown it across the room.”
With my guard in, I initially found it hard to fall asleep, and felt nauseous. And it’s hardly romantic, although the lesser of two evils when the alternative is keeping a partner awake with grinding, which can affect intimacy.
Unfortunately there is no magic solution to getting used to it, although a custom-made mouthguard is likely to be more comfortable. I persevered, and Dr Stern insists, it’s worth it: “The guard can work not just to protect the teeth, but actually to reduce or eliminate the bruxism.”
“Bruxism isn’t necessarily there for life,” says Dr Stern. “It can come and go.”
This was the experience for Jo, who says: “I haven’t experienced the symptoms for a while; my body tends to cycle through different physical symptoms when I’m stressed, and at the moment, I’m not in a jaw-clenching phase.”
This is why it’s important to tackle teeth grinding from more than one angle: a mouthguard to minimise damage, but also, addressing contributing factors.
“When my dentist suggested I was grinding my teeth, she was being tactful; I was pulverising them”
Natasha Crowe says that grinding our teeth is part of the pattern of how stress and anxiety lead to tension in the body: “The body can’t relax and feel tension at the same time,” she says. “One client said to me, ‘It’s like I take a breath in the morning and I don’t let it out until I get home,’ and it’s so true.”
The manifestations of that tension can easily compound stress or anxiety. It becomes a vicious cycle, and finding a balance can be tricky. Charlie suffers from generalised anxiety disorder, and discovered that anti-anxiety medication made her bruxism worse: “I started to get a really stiff, sore jaw, and noticed a clicking sound when I opened and closed my mouth. Now, I have regular acupuncture to treat both the pain in my jaw, and also the underlying anxiety, which I have found really helpful.”
Like Charlie discovered, while teeth grinding treatment is focused on protecting and saving the teeth, prevention is much more holistic. Dr Ahmed talks to his patients about reducing stress: “Things like relaxing music, exercising, and mindfulness. Sometimes we refer patients to a psychiatrist or a GP regarding CBT.”
The most important thing is to acknowledge it, says Natasha: “Once you become aware of it, you the have the ability to take control and have the power over it.”
