New and need help!!!!

can anybody help? Just moved back to my home town to be near my family and my 22 month old has settled in well but she@ started to scream when you put her to bed,i've tried everything from medicine in case its teeth(can't feel anything) to ignoring it. if it wasn't for my mum would have had a breakdown by now. its made worse for the fact she's always been such a good child and was a fantastic baby. anybody have any ideas? she's my first and i'm totally out of my depth
