Teeth grinding and facial irritation is more prevalent as a result of coronavirus-related stress and anxiety.

According to a report, 50% of Israeli women suffer from severe teeth grinding and/or facial muscle discomfort.

The stress and anxiety experienced by the general population during Israel’s first lockdown brought about a significant rise in orofacial and jaw pain, as well as jaw-clenching in the daytime and teeth-grinding at night, according to a new study from Tel Aviv University (TAU).

Additionally, the study discovered that women suffered from these symptoms at a greater rate than men, and that 35- to 55-year-olds suffered the most. “We conclude that our results represent the suffering experienced by the middle generation, who were cooped up at home with small children without the normal assistance of grandparents, while also worried about their elderly parents, who were also experiencing financial difficulties and often needed to operate from home under trying circumstances,” the researchers write.

Dr. Alona Emodi-Perlman and Prof. Ilana Eli of TAU’s Goldschleger School of Dental Medicine were the study’s principal investigators. On October 12, 2020, the article was written in the Journal of Clinical Medicine. The report analyzed questionnaires that measured the prevalence and potential worsening of these conditions in the general public after the first COVID-19 lockdown, which was triggered by a national emergency and an increase in anxiety levels. A total of 1,800 respondents in Israel and Poland completed the questionnaire. During Israel’s initial lockdown, the general public experienced a significant increase in orofacial discomfort, as well as daytime jaw clenching and nighttime teeth grinding – physical manifestations often induced by tension and anxiety. The incidence of signs increased from approximately 35% pre-pandemic to 47%; the prevalence of daytime jaw clenching increased from approximately 17% to 32%; and nighttime teeth chewing increased from approximately 10% to 36%. Individuals who had experienced these symptoms prior to the pandemic recorded an increase in incidence of around 15%.

In total, a 10%–25% increase in these symptoms, which often indicate emotional stress, was observed. Additionally, by compared observations in Israel to those in Poland, the researchers discovered that respondents in Poland had a significantly higher risk of having TMD or Bruxism. Drs. Nir Uziel and Efrat Gilon of TAU collaborated on the report, as did researchers from the University of Wroclaw in Poland, who studied the Polish population’s response to the pandemic.
