I couldn't understand why "зуб" is in genitive case(зубов) in the following sentence. What is the grammatical explanation for that?

у меня в два раза больше зубов,чем у тебя.

    Not exactly a duplicate as this is different case (pun not intended), but check this discussion: https://russian.stackexchange.com/questions/418/%d0%bd%d0%b5%d1%82-%d0%b3%d1%80%d0%b0%d0%bc%d0%bc-vs-%d0%bd%d0%b5%d1%82-%d0%b3%d1%80%d0%b0%d0%bc%d0%bc%d0%be%d0%b2-a-new-case-or-two-different-words-with-separate-p – Swift Apr 22 '17 at 04:05
  • Why "a lot" uses Genitive in English? – Anixx Apr 24 '17 at 21:27

The explanation is very simple - you must use genitive after больше and меньше as well as after много and мало or telling an exact number (у меня десять пальцев и сто тысяч волос).

"more teeth" and "less teeth" in Russian is like in English "number of teeth" using of. Like if in English you would say "more of teeth". And word of indicates that the next word is in genitive case.

Words which describe inexact quality govern genitive plural: много котов, мало котов, больше котов, чем у тебя, немного котов, несколько котов, столько же котов, сколько у вас котов...

Words which describe number also govern genitive plural unless then end by 1,2,3,4, but not 11,12,13,14: 8 котов, 112 котов.

However, quantors есть коты, некоторые коты, все коты govern nominative plural.
