In a short video uploaded in September 2026, BBC News reports that dentists in the UK are seeing more young people grinding their teeth. Teeth grinding (bruxism) means clenching or grinding the teeth without meaning to, and it can happen while you are asleep or awake. The NHS says stress and anxiety are the most common cause; it is also linked to sleep problems such as snoring and sleep apnoea, some medicines for sleep problems, depression or anxiety, smoking, and drinking a lot of alcohol or caffeine.
What it means for you
Waking up with an aching jaw or a headache, sensitive teeth, or a filling that suddenly falls out can all be linked to grinding. The NHS says grinding can wear down or break teeth, so spotting it early can save you treatment later.
Editors' take: the background
The NHS page on teeth grinding says treatment is not always needed. But you should see a dentist if your teeth are damaged or sensitive, if you have pain in your jaw, face or ear, or if a partner says you grind your teeth in your sleep. A dentist can fit a mouth guard or splint to your upper or lower teeth, worn at night to protect them. If grinding is linked to stress, anxiety, smoking or drinking, the NHS suggests also seeing a GP. Day to day, it suggests relaxing with breathing exercises, music and regular exercise, going to bed at the same time each night, and avoiding chewing gum and hard foods while your jaw hurts.
The video describes a trend UK dentists are noticing. If you already have jaw pain, teeth that are getting shorter, or a tooth you think may be cracked, our guides on jaw-joint (TMJ) problems, bite wear and cracked teeth explain the treatment options and costs in Hong Kong.
