Bryce Harper's unique toothbrushing technique has sparked a viral sensation. The Philadelphia Phillies star shared a TikTok video showing him squeezing toothpaste directly into his mouth, rather than onto a toothbrush. This unusual method has drawn both amusement and concern from fans and dental professionals. Ohio dentist Andrew Zucker advises against Harper's approach, suggesting it wastes toothpaste and could spread germs. Despite the criticism, Harper is unfazed and happy about the viral attention. Dentist Maria Ryan appreciates Harper promoting dental hygiene but cautions against his method.
