Jaw clenching, known as bruxism, affects more than 10 million adults in the UK. Episodes can last from a few seconds to several minutes, according to dental solutions expert Tony Taunk of Implant Perfection.
Taunk says the habit is often linked to periods of stress and anxiety, and it can also be associated with lifestyle factors such as excessive caffeine intake and smoking.
What damage can it cause?
“If left unchecked for a long period of time, jaw clenching can lead to damaged tooth enamel, jaw pain, earaches and headaches,” Taunk said.
It can also make teeth more sensitive as they become worn down, and some people find it disturbs their sleep.
How to prevent it
To avoid long-term health issues, Taunk says the underlying cause needs to be tackled. Reducing stress, cutting out or reducing caffeine and alcohol, and behavioural therapy can all help.
Regular exercise, avoiding hard foods that are difficult to chew, and ensuring a calm sleeping environment and routine may also reduce jaw clenching.
Mild cases may be temporary and do not always require treatment, but more serious cases should be tackled as soon as possible. For those who clench at night, a custom-made mouth guard from a dentist can prevent further damage.
Underlying causes and treatment
Jaw clenching can occur during sleep or while awake, sometimes without people realising. A common cause is misalignment of the jaw.
Treatment options for misalignment range from orthodontic devices such as braces or a retainer to physical therapy, including muscle relaxation techniques and massages.
Taunk advises anyone who notices clenching more often than usual to speak to a dentist, who can help identify the cause and find the right treatment.
