In my clinic, I’ve seen athletes using protein shakes and energy gels. These contain sugar and stick to teeth, leading to black pits and cavities if not cleaned immediately. Also, some people grind their teeth (bruxism), which wears off enamel, making stains more pronounced. Surprisingly, even chlorhexidine mouthwash, often prescribed for gum problems, can stain teeth dark if overused.
