Obviously remove from play anything not meant for teething like board books - my books don't go in the mouth period for any reason. Same with puzzles - if we can't play with things they were intended we don't get them because it isn't fair to the others to have their things destroyed.

There are teething drops and rubs and creams and while I am not anadvocate for them for a child like this they need some more assistance so I would be asking mom to provide them. Also it is very common - no matter what some experts say - for a child to get an ear infection or throat infection at the time of teething due to the extra build up of fluids - same thing that causes the extra drooling as in it has to come from somewhere so be sure that that has been ruled out if child is really that upset.

If she is chewing on plastic food she is looking for something harder than squeeky toys and softer than hard toys. I have a few cheap toys meant just for this. They were a set of alphabet letters which fit in the mouth well. There is a giraffe toy from toysrus some moms swear by. There is a teething necklace that is supposed to help and we discussed that on here at one point but I won't allow them in daycare so have no idea if they work.

If child is just going to chew and cry anyways go ahead and put her in a playpen or play yard and give her only access to acceptable chewing toys - empty yougurt type containers work well actually as they fit the curve of the mouth. Then just recycle when done.
