Of course! Don't they make a product for everything these days!!:) I don't know the name of it but either google it or go to your local CVS and it's there.It's just a nasty tasting solution you brush on. Hopefully she is young enough it will work. My daughter did the same thing at age 8 and nothing worked. It's a hard habit to end.She outgrew it thank goodness! Try to distract her with something else. Keep her hands busy and moving if you can. Give her a hobby that requires her hands. Play-doh,drawing etc.....Good luck!!:)
