The study, which was published on Oct. 12 in the Journal of Clinical Medicine, used a questionnaire to examine whether participants had experienced worsening symptoms during the COVID-19 pandemic.
The study authors noted that the stress and anxiety associated with the constant threat of illness, economic concerns, and social isolation could lead to adverse health effects like temporomandibular disorders (TMD) and bruxism (teeth grinding).
Their study was aimed at confirming whether this was the case.
Nearly 1,800 people residing in Israel and Poland took part in the study.
The researchers found that during Israel’s first lockdown, there was a rise in orofacial pain, which is a symptom generally associated with stress and anxiety.
In addition, the prevalence of this symptom increased from about 35 percent prior to the pandemic to 47 percent during. And the prevalence of jaw clenching during the day increased from about 17 percent to 32 percent.
Also, teeth grinding at night went from about 10 percent to 36 percent.
The overall severity of the symptoms also rose by about 15 percent.

Leena Palomo, DDS, a professor and board certified periodontist at Case Western Reserve University, said that “anyone stressed could be at risk — anyone challenged to balance conditions and emotions is susceptible to clenching and grinding.”
Regarding potential symptoms, Palomo noted, “Clenching during waking hours is easy to recognize because people are awake.
“People who grind overnight often wake up with a sore jaw, stiff neck, or pain referred around the head and neck,” she added. “This pain may mimic an earache or headache.”
Another important sign to look for, according to Arman, is tooth wear.
