6 month & teething......?

My son just cut his 2 bottom teeth...both are all the way broke through the skin, can he still fuss from this? He seems to fuss a lot. I have already been through the colic and changing of formula, also he had acid reflux...then a double ear infection.So my lil man has had it rough, but I take him every few weeks for check ups just to make sure his ears look ok and he is gaining weight but recently since the teething he has been so fussy, not wanting to eat much and I am just wondering if it can still be from him cutting his teeth??
