Teeth Grinding on the Rise Among Young People, Dentists Warn

Ella woke most mornings with her jaw locked in pain, her face visibly changing shape, her molars worn down to nubs. She couldn't pinpoint when the grinding started—only that it had become relentless, a nightly assault she couldn't control. At 31, she finally understood what was happening: bruxism, a condition that makes the jaw clench and grind with such force that teeth fracture, headaches bloom behind the eyes, and sleep becomes something that happens to other people. When her dentist warned her that her teeth were at risk of breaking entirely, she knew she had to act.

Ella is far from alone. Millions of people across the UK grind their teeth, though many never realize it until the damage appears. Some research suggests nearly one in four people experience bruxism at some point, yet the condition remains largely invisible—a private torment that happens in the dark. What's changed recently, according to dentists and mental health professionals, is the sheer number of young people now seeking help. The British Dental Association has no hard figures, but anecdotal evidence is mounting. Dr. Aditi Desai, president of the British Society of Dental Sleep Medicine, says the rise is unmistakable. "It is definitely on the rise," she explains, "and it's no surprise given that life itself nowadays can be so stressful."

The mechanism is straightforward once you understand it. Stress and trauma push the body into fight-or-flight mode—heart rate climbs, adrenaline floods the system, muscles tense. The jaw and nervous system are wired together through major cranial nerves, so when the brain signals danger, the jaw responds by clenching and grinding. For people like Ella, who describes herself as having high-functioning anxiety, the grinding becomes a release valve. She's busy, she goes out constantly to mask the anxiety, and at night her body does what it cannot do during the day: it lets the tension out through her teeth. Psychotherapist Rahi Popat has noticed this pattern accelerating in his practice, particularly among younger clients. They come in aware that their grinding has intensified during stressful periods, able to draw a direct line between what's happening in their lives and what's happening in their mouths.

But teeth grinding is not always the villain in the story. Prof. Frank Lobbezoo, a leading researcher on bruxism, points out that the condition can actually serve vital functions. When the jaw moves, it activates the salivary glands, which clean the mouth, protect the teeth, and aid digestion. Some evidence suggests that jaw movement stimulates blood flow to the brain, potentially helping with cognition. Most strikingly, in cases where obstructive sleep apnea is present—where the airway becomes blocked—grinding can literally keep someone alive by moving the blockage enough to restore breathing. "That's a very good example of why bruxism can keep you alive," Lobbezoo says. The condition is not simply a mechanical problem of the jaw, as it was once understood. It is, as prosthodontist Riaz Yar explains, a "biopsychosocial issue," shaped by sleep patterns, diet, weight, exercise, medication, and the whole architecture of a person's life.

The damage, when it comes, can be severe. Dr. Simon Cove, a dentist who uses 3D scanning to track wear over time, has seen teeth ground down so far that restoration becomes extraordinarily complex and expensive—sometimes costing thousands of pounds. Chronic jaw and facial pain can develop, disrupting sleep and daily function. Yet many dentists, Desai warns, hand out mouthguards without ever investigating why the grinding is happening in the first place. A mouthguard protects the teeth but does nothing for the underlying cause.

Ella chose a different path. She paid privately for Botox injections into her masseter muscles—the muscles that control jaw movement. The procedure relaxed them, reducing tension in her face, and the effects last three to four months. Within weeks, she was sleeping properly, waking with energy instead of pain, her face no longer locked in a square clench. But she also began meditating to address the anxiety itself. Treatment, she now understands, means addressing both the symptom and the source.

For most people, the approach is less dramatic but equally multifaceted. A mouthguard at night protects teeth. If sleep apnea is present, devices like a CPAP machine or mandibular advancement device keep the airway open. Physiotherapy, cognitive behavioral therapy, and lifestyle changes—exercise, reduced alcohol, better sleep, stress management—all play a role. The condition requires what Yar calls a multidisciplinary approach, one that treats the person, not just the grinding. Ella's transformation—from chronic pain and facial distortion to restored sleep and reduced anxiety—suggests that when dentists, therapists, and patients work together to find the root, the relief can be profound.
