Betel nut staining can leave a distinctive mark on the teeth. Long-term chewing of areca nut, often combined with betel leaf and other ingredients can produce deep red, brown, or black staining and characteristic patterns of dental wear. Because the practice has strong cultural and geographic associations, forensic anthropologists can sometimes use these dental changes alongside other evidence to help suggest the general region or cultural background an individual may have come from. #learnontiktok #bonetok #learnontiktokcontest
