Help!! 8 month old sleep problems

As

So recently my almost 8 month old girl has been super fussy, fighting her sleep on a whole new level. She is now taking about 2 one hour naps a day! And going to bed between 8 and 830 at night! She screams bloody murder when going down for bed. And has been super fussy during the day! She has 5 teeth and 3 of them have popped through but are still working on getting higher. Could this all be due to teething?? Her first two teeth we had no issue at all. She has her top two k9 teeth popped through and a third tooth beside her other two teeth. Tylenol Does not help. She is crying so hard at night she has been making herself sick and puke.
