Please be kind because I'm scared to death. A few days ago I noticed my lower incisor has a grayish spot, it was sensitive to drinks, then I noticed brown colour on the edges, I suppose that's cavity and I have it everywhere on almost all front teeth?? I have had a lot of fillings, but never on the front teeth. Also now everything kind of hurts, my jaw also. I have an appointment in 4 days and I'm willing to pay whatever but it's really hard to get an appointment right now (I can't risk with random dentist though). I also know it won't be possible to do everything in one day, if there's many cavities, it'll take weeks. So my question, what can I do to stop spreading the cavities too fast? https://i.postimg.cc/Y0CNMg1n/IMG-20210510-140304.jpg
