Plural of dentistry; multiple dental practices, specialties, or fields of dental science and treatment.
From 'dentistry' (dentist + '-ry' suffix meaning practice or profession) + '-ies' (plural). Dentistry itself derives from Latin 'dentis' (tooth).
While you'd normally say 'branches of dentistry' rather than 'dentistries,' the plural form reminds us that dentistry has become so specialized that there really are multiple sub-fields: cosmetic dentistry, pediatric dentistry, oral surgery, and more are almost like different professions.
