Advantages like some teeth (6)
I believe the answer is:
assets
'advantages' is the definition.
(an asset is something advantageous)
'like some teeth' is the wordplay.
'like' becomes 'as'.
'some teeth' becomes 'sets' (I can't explain this - if you can you should believe this answer much more).
'as'+'sets'='ASSETS'
Can you help me to learn more?
(Other definitions for assets that I've seen before include "One's goods and property" , "worldly goods" , "Personal wealth" , "Properties that have money value" , "One's valuable possessions" .)
