This may be a stupid question

Please bear with me mamas. My little one is 11 months and he already has 7 teeth, I notice he has 1 maybe 2 more coming soon. Well the first 7 teeth he wasn’t very fussy but I’ve been noticing that at night when he’s sleeping he wakes up a lot in pain, he moves around a lot and cries and eventually will try and fall asleep again but I’m pretty sure it may be his teeth. Should I give him Tylenol? Does it really help.. his doctor has already said that he can have Tylenol so the doctor is saying it’s fine but I’ve never had to give him medicine before and I’m just wondering if I should just give him some so that the pain will go away
