Form of candy good for the teeth? (5)

Ross

I believe the answer is:

floss

I'm a little stuck... Click here to teach me more about this clue!

'for the teeth?' is the definition.
(I have seen 'Clean teeth' mean 'floss' so perhaps 'teeth' could also mean 'floss')

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for floss that I've seen before include "Eliot's river" , "Clean between the teeth" , "Silk" , "Teeth-cleaning thread" , "A mass of silky fibres - dental?" .)
