As the world came to a standstill due to COVID-19, we initially focused on the respiratory symptoms associated with the virus, such as severe coughing and breathing difficulties. However, as time passed, it became clear that COVID-19 affects much more than just our lungs. It has repercussions on multiple bodily systems, including gastrointestinal, neurological, vascular, and cardiac functions.
Now, emerging evidence suggests that our dental health is also suffering—both directly and indirectly. The stress of the pandemic has led to an uptick in teeth grinding and jaw clenching, along with many individuals postponing dental appointments. Moreover, there are anecdotal reports of tooth loss following COVID infections, indicating that our dental health may be at risk during this challenging time.
We consulted with Dr. Sarah Jennings, a dental professional and educator at Oakwood University Dental School, regarding the pandemic’s effects on dental health, particularly concerning bruxism—teeth grinding and jaw clenching.
Why Are We Experiencing Increased Teeth Grinding?
There are two primary factors contributing to the rise in bruxism. The first, unsurprisingly, is stress. Nearly a year into the pandemic, many of us are living under the weight of anxiety stemming from various social, economic, and political challenges. This chronic stress keeps our bodies in a heightened state of tension, leading to teeth grinding at night, as noted by Dr. Emily Park, D.D.S., in an article for The Health Journal.
The second factor is posture. “Poor posture during the day can lead to increased grinding at night,” Dr. Park explains. With many individuals working from home at makeshift desks, it’s common for posture to suffer. This can create tension in the neck and jaw, increasing the likelihood of grinding during sleep, adds Dr. Jennings.
Certain medications for anxiety and depression can also heighten muscle activity in the jaw, potentially exacerbating bruxism during the night.
Consequences of Teeth Grinding and Clenching
Grinding or clenching teeth can lead to a range of issues, including facial pain, difficulty opening the mouth, headaches, neck pain, and even damage to teeth and dental restorations. In fact, Dr. Jennings reports an increase in patients needing to replace broken mouth guards, with her practice experiencing significant demand for appointments related to jaw disorders.
Long-term effects of bruxism can lead to cracked teeth, worn enamel, and pain in the jaw joints and muscles used for chewing.
How to Address Teeth Grinding at Night
The challenge with nighttime grinding is that many individuals are unaware they are doing it. Addressing the root causes is crucial, but a common treatment is the use of a custom mouth guard designed to alleviate symptoms. Dr. Jennings mentions that while over-the-counter mouth guards can serve as a temporary measure, a personalized solution is preferable for effective relief.
In addition, specific jaw exercises can help. For instance, gently massaging the sides of your face while keeping your teeth apart may provide relief. Spending just a few minutes each day on these exercises can be beneficial. If daytime clenching is an issue, keeping the teeth apart and resting the tongue on the roof of the mouth can also be helpful.
Potential Tooth Loss Among Long COVID Patients
The connection between COVID-19 and tooth loss remains largely anecdotal, particularly among long-haulers—those who continue experiencing symptoms long after their initial infection. Dr. Mark Thompson, a health researcher, noted in a recent article that medical professionals are beginning to investigate the unusual symptoms reported by these individuals, including tooth loss.
Dental Offices Are Safe
Regardless of the dental issues you may be facing—grinding, clenching, or otherwise—it’s essential not to skip dental appointments. “Oral health is a critical aspect of overall health,” asserts Dr. Jennings. Dental professionals are well-trained in infection control, ensuring that practices have adopted new measures to keep patients safe.
The pandemic has altered many facets of our lives, including how we work and interact. While we await a return to normalcy, we can take proactive steps to protect our dental health now.
