What dentist uses to scrape around base of incisor? (4)
I believe the answer is:
burr
'scrape around base of incisor?' is the definition.
'burr' can be an answer for 'scrape' (thesaurus). I'm not certain of the 'around base of incisor?' bit.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for burr that I've seen before include "Former US vice-president - dialect way of pronouncing R" , "trouble" , "manner of speaking)" , "Seed vessel" , "English dialect sound - notorious US vice-president, charged with treason" .)
