This is going to be blunt, but Jenna, I'm really worried by the amounts of both paracetamol and codeine. Does your health care provider know how much you take of each?
There are other far more beneficial medications, but TBH Upping the dosage is not going to make any difference to your pain. Too much paracetamol can damage your own liver. I really think it's a good idea to speak to someone about a long term pain management plan.
Can your teeth not be taken out with a local anaesthetic in the chair?
