How Stress Affects Kids’ Teeth: From Grinding to Cavity Risks

Stress doesn’t just affect adults—it impacts kids, too. And while we often think of emotional or behavioral signs of stress, it can also take a toll on children’s dental health. At Kenmore Pediatric Dentistry, we want to help parents understand how stress can show up in their child’s mouth and what you can do about it.

What Parents Should Know About Stress In Kids & The Connection To Their Teeth

Teeth Grinding (Bruxism)

One of the most common signs of stress in kids is teeth grinding, especially at night. This habit, known as bruxism, can wear down tooth enamel, cause jaw pain, and even lead to headaches. If your child complains of a sore jaw in the morning or you hear them grinding their teeth while they sleep, it’s worth bringing up during their dental visit.

Mouth Sores and Cheek Biting

Stress may also cause children to develop mouth sores like canker sores or to chew the inside of their cheeks or lips. While these habits often go unnoticed, they can cause discomfort and lead to infection if not addressed.

Increased Risk of Cavities

Stress can affect appetite, sleep, and daily routines—including brushing and flossing. Kids who are feeling overwhelmed might snack more often, skip brushing, or crave sugary comfort foods, all of which increase their risk of developing cavities.

What Parents Can Do To Help:

• Create a calming bedtime routine to reduce nighttime grinding.

• Talk to your child about their feelings and look for healthy outlets for stress, such as exercise or creative activities.

• Keep a consistent oral care routine with brushing twice a day and flossing once.

• Visit us regularly so we can monitor for signs of stress-related dental issues and offer solutions like night guards if needed.
