Hi. I received a deep filling on my lower left that does not hurt when not in use. I can chew things like bananas and soft food no pain. When I bite a pretzel or something hard it jolts pain. It feels like the filling is loose or there's pressure in the tooth. That's from may! Now I've had another filling done and dentist said it's not as deep. It's been 2 weeks and that one stings with crunchy food and it's a similar feeling. I also have gotten ear infections after each filing. Do you think it's possible this will heal. They suggested crown for the first but I don't really trust them. I had no tooth pain, got fillings, have tooth pain. TIA
