The Krispy Kreme Challenge and Oral Health: How Local Events Keep Us Smiling

At North Raleigh Periodontics and Implant Center, we love supporting our community—and there’s no better example of local tradition than the Krispy Kreme Challenge. For local residents, it’s a familiar and beloved event: participants run 2.5 miles from NC State’s Memorial Belltower to the Krispy Kreme on Person Street, eat a dozen donuts, and then run 2.5 miles back to the belltower. This quirky challenge has been a Raleigh tradition for over 20 years and benefits UNC Children’s Hospital, bringing together runners, families, and supporters from across the Triangle. While it might seem ironic for a dental practice to show up at a donut‑themed run, our team chose the path of exercise, fun, and community support—participating in the run itself and leaving the dozen donuts to the more competitive eaters!

Physical activity does more than strengthen your heart and lungs—it also supports your oral health. Regular exercise has been shown to reduce systemic inflammation, which plays a role in gum disease.

One little‑known fact is that individuals who stay active tend to have lower levels of C‑reactive protein, an inflammatory marker linked to periodontitis. Staying active also supports immune function, helping the body better manage the bacteria responsible for gum disease and tooth decay. Even moderate activities like walking, jogging, or participating in fun community runs contribute to healthier gums over time.

Maintaining good oral hygiene goes beyond brushing and flossing—even small habits can make a difference. For example, xylitol‑sweetened gum or mints can help deter cavity formation by stimulating saliva flow and lowering the acidity in your mouth, making it harder for decay‑causing bacteria to thrive. While it’s no substitute for daily brushing and professional cleanings, this little trick can serve as a helpful complement—especially after meals when brushing isn’t immediately possible.

Mental wellness and social connection also matter for your smile. Chronic stress increases cortisol levels, which is associated with higher levels of gum inflammation. Events like the Krispy Kreme Challenge, filled with laughter, camaraderie, and shared purpose, naturally help reduce stress hormones and strengthen emotional well‑being. Studies have shown that people who participate regularly in community activities and maintain positive social connections tend to enjoy better oral health outcomes than those who feel isolated or overly stressed. A joyful day out with friends and neighbors can do more than lift your spirits—it can support the health of your gums, too.

Of course, preventive care remains the cornerstone of a healthy smile: brushing, flossing, and regular dental checkups are essential. But when you pair those basics with a physically active lifestyle, stress‑reducing experiences, community involvement, and small supportive habits, you’re giving your mouth the best chance to stay healthy and vibrant.

Our team at North Raleigh Periodontics loved being part of the fun, the fitness, and the fellowship of the Krispy Kreme Challenge —and we’re reminded that a healthy lifestyle supports every part of you, from your heart to your gums to your grin. So keep moving, keep laughing, and keep smiling—because healthy habits, joyful experiences, and community involvement are all pieces of the puzzle for a strong, confident smile!
