My 3 year old is getting worse as time goes by with putting things in her mouth

My 3 year old always sucked her thumb even at birth, at first I thought it was cute but then she started getting a over bite & now not only is she putting her thumb in her mouth she sucks all her fingers & string like purposely take thread out of her clothes or blankets to put in her mouth she bites her nails put her shirt in her mouth she plays with her tongue she licked herself & now she rubs on people for God knows what reason. When I try to get her to stop or tell her to stop she cries, wine, or throw a fit then does it again like I never said anything What do I do
