no dent and dentist are unrelated words. A dent = picture of a dent https://www.thunderbolts.info/tpod/2006/arch06/060324spacetime.htm dentist = from dental/ teeth a tooth doctor. I have heard only two or three people in my entire life say "animal doctor". Veterinarian is correct. or In UK English a vet.

Due to the Norman (French) Conquest of 1066, English has a large number of French words. In French, dent is tooth and dentiste is tooth doctor. Dentist is an English variant of the French dentiste.

Hey Hiro, The noun dent has no relation to the noun dentist. The fact that the word "dent" is found in the word "dentist" is purely coincidental. When it comes to healthcare most professions have specific nouns to describe them, for example, some people may say "the eye doctor" but is actually an Ophthalmologist or an optometrist. When it comes to veterinarians, calling them animal doctors is grammatically correct as they are technically exactly that. However, they are not medical doctors per se. They have a title, that is a veterinarian. Recognizing people's jobs and titles is often polite and shows respect. With some professions, you will just have to memorize the official titles.
