I fell foul on literal translation

I repeatedly fall foul over “docteur” vs “médecin(e)”, and became even more confused with the phrase “why do you want to see the doctor” when the call was made to see the dentist. So I’m thinking, should it be “want to see the doctor Bernard”. My understanding is “docteur” is the title, and “médicin(e)” is the profession, and in this case “le dentist”. And then I’m tripped up by “teeth cleaning” when in practice you would probably say “a descale” but that didn’t come to mind at the time !
