I believe the answer is:

uppers

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

'drugs needed for teeth' is the definition.
'uppers' can be an answer for 'drugs' (I've seen this before). I'm not certain of the 'needed for teeth' bit.

This is all the clue.

Can you help me to learn more?

(Other definitions for uppers that I've seen before include "pills" , "Top parts of shoes" , "the poor are on?" , "The 25 [PENNILESS] are on these" , "Parts of shoes above the sole" .)

I've seen this clue in The Telegraph.
