Stress and Teeth: The Link Between Emotional and Oral Health

There are surprising connections between stress and teeth. According to the American Psychological Association’s  “Stress in America” survey, a majority of Americans say their stress levels have increased over the past five years, with around 75% reporting physical or emotional symptoms related to stress. To help prevent and mitigate effects, a comprehensive approach can include stress management, consistent oral hygiene habits and regular dental visits. Review the following information to learn about the connection between stress and oral health and how to help support employee well-being.

The impact of stress on oral health

Many people are aware of the physical and emotional symptoms of stress, such as headaches, stomach discomfort, and anxiety, but may not realize that stress can also affect their oral health. Studies show that chronic and high stress can negatively impact oral health by suppressing the immune system, decreasing saliva production, and triggering unconscious tension or poor dietary habits. Understanding how workplace stress affects oral health can help HR and benefits leaders design programs that potentially reduce claims costs and support employee well-being holistically.

Teeth grinding (bruxism)

Sometimes when people are stressed, they clench or grind their teeth, often while sleeping, without realizing it. This can wear down dental enamel, causing tooth sensitivity, jaw pain, headaches, and even cracked teeth. Dentists may recommend a night guard to wear while sleeping to protect the teeth and jaw. The damage to teeth can cause expensive restorative procedures but can be caught early with regular dental visits.

TMJ disorders

The jawbone is connected to the skull by the temporomandibular joint, also known as TMJ, which acts as a hinge. There is one TMJ on each side of the jaw. Clenching and grinding teeth can cause pain in the TMJ and the muscles that direct jaw movement. If your employees have jaw pain, they should contact their dentist for an evaluation. The dentist will determine the reason for TMJ pain and recommend treatment options. Common treatments are medications to relieve inflammation, a night guard, crowns to balance biting surfaces, physical therapy, or surgery.

Sores in and around the mouth

Canker sores are small spots with white or grayish centers surrounded by red borders inside the mouth that can cause pain when chewing or talking. Canker sores are not contagious. Cold sores (also called fever blisters) are painful, filled with liquid, and most often appear outside the mouth, on or near the lips. Cold sores can be spread easily to others, and care should be taken not to share utensils or drinks.

Dry mouth

Saliva is a natural cleanser that helps wash away food debris and neutralizes acids produced by bacteria. If the mouth doesn’t produce enough saliva, employees may have chronic dryness, which can be uncomfortable and make it harder to taste, chew, and swallow. Dental professionals believe age, stress, radiation therapy for cancer, and some medications used to treat depression can reduce saliva flow. This can increase the risk of developing tooth decay and gum disease. If an employee has any of these symptoms, they should visit their dentist for treatment options.

Tooth decay and gum disease

Employees under chronic stress are more likely to neglect preventive care, possibly increasing claims burden and contributing to more costly restorative procedures down the line. They may adopt unhealthy behaviors, such as snacking on foods and drinks that are high in sugar throughout the day, skip brushing or flossing — all of which can lead to a decline in oral health. Some people turn to alcohol, tobacco, or drugs to manage stress, which can also increase risk for oral diseases.

It’s important to recognize that employees commonly experience stress related to work, school, relationships, and even world events. Employers can play a key role in helping them build healthy coping skills and manage that stress effectively. For example, employers can foster healthier habits by promoting mental‑health resources, encouraging flexible breaks, supporting time off for routine dental care, and more. Proactively investing in employee mental health not only improves overall well‑being but can also contribute to better oral‑health outcomes and can reduce long‑term benefits costs. When employees stay mindful of their oral, mental, emotional, and physical health, they’re better equipped to live happier, healthier lives.
