Canadian dentists report increase in cases of stress-related tooth grinding
Dentists in Canada have reported an increase in cases of stress-related tooth grinding during the pandemic.
Dental professionals claim that they have seen a growing number of patients presenting with symptoms of tooth grinding (bruxism) and clenching in the last 18 months. Symptoms include split and cracked teeth, headaches and jaw pain.
Dr Bruce Ward, a dentist from the Vancouver area, said that there has been a steady stream of patients experiencing symptoms of bruxism during the pandemic, as rising stress levels take their toll.
People are coming in with broken and chipped teeth and pain in their jaw due to grinding or clenching the teeth while they sleep. Recently, Dr Ward removed two teeth, which were split right across the middle due to the pressure of grinding during the night.
Dr Ward, a former president of the British Columbia Dental Association, said that his experience is echoed by others. During Zoom meetings with fellow dentists, many report the same issues. There has been a noticeable rise in cases of damaged teeth and pain in and around the TMJ (temporomandibular joint) as a result of bruxism linked to stress and anxiety.
Dr Ward explained that the teeth are designed for grinding and breaking down food, but involuntary clenching causes significant weakness, which increases the risk of splitting and cracking.
The action of grinding the teeth together, he said, is like “two pieces of ivory rubbing.” As well as damaging the teeth, bruxism can also contribute to stiffness and pain in the jaw, clicking and popping noises and restricted movement in the temporomandibular joint.
Bite guards are commonly used to prevent bruxism. These devices sit in the mouth during sleep to ensure that the top and bottom arches of teeth do not collide.
