How many Tylenol can I take in one day?

So I have a tooth that needs a route canal; I got an emergency dentist appointment in today but they can't do work until they get it approved. They so as there rushing it so it will take 2-3 days rather than 2-3 weeks to be approved since I'm in throbbing pain and can hardly even eat. They took a X-ray, which I called my doctor to make sure it was safe and she said it was as long as I was covered; they covered me with 2 aprons. They prescribed me amoxicillin(I am terrible at taking pills so I break them open and mix it in a drink that I take like a shot) and I've been on tylonal every time it eat a meal. I have another route canal on the other side of my mouth that is not yet done so I only have this side to chew on, because that side is uncomfortable to chew on and I don't want my temporary cap to pop off. The side I have to chew on the pain is nearly unbearable.  I have to cut my tylonal pills into 3s to take it. How much is too dangerous ? I've taken 2 today so far, I just don't want to hurt my baby. My baby shower is also tomorrow, perfect timing to be miserable in pain right ?🙄😭😞
