Have you ever woken up with a headache or stiffness in the jaw? Or has your dentist ever reported wear on you teeth from grinding?

If so, you may suffer from bruxism — involuntary grinding of the teeth, usually during sleep. Bruxism can also present itself during the daytime, sometimes caused by stress, a misaligned bite, or excessive caffeine.

Periodontal disease has never been more relevant.

New research shows hospitalized coronavirus patients are more likely to die of respiratory failure if they suffered from periodontitis before contracting COVID-19, according to an international team of dental researchers.
