right missis is 36 week preg and cant take anything other than paracetemol and just been told cant take as many as says due to her state

she lost a filling other day and got toothache, in agony i took her yo chorley hospital for emergency dentist as she was in agony, they gave her a tempory filling and antibiotics but couldnt xray her to see prob again as preg.......
this was yesterday, now she cant open mouth etc and is crying her eyes out in pain,rang emergency dentist who said antibiotics will start working soon but its killing me to see her in so much pain.....
Anyone any good tips for toothache?? bearing in mind she is ready to drop?
