When I lost my baby teeth, (kindergarten I think) it took a full nine months for my permenant uppers to break my gums. That being said what is most likely happening is that the gums in that area are hardening. the teeth are trying to cut through and since the gums are hard it is not happening. My aunt has had the issue with several of her children and so she cut the gums herself! Now I am not reccommending you do it yourself per say but basically it really isn't a huge deal. She sterilizes a straight razor blade and cuts the teeniest tinyest slit on top of the gums. She has even done it on her babies when their teethe hadn't come in by like 10 monthz. the gums harden especially with babies because they have no teeth and chew on everything. Maybe check with your dentist on how long you can wait until you have "the procedure." At least at the dentist they will be able to properly numb the area. Also check to see what can be done to prevent it for future teeth. I know that chewing makes the gums harder so I really have no idea how to soften them. good luck.
