I got my first filling yesterday at 27, and was super nervous already for it (ive never had a cavity in my life), and almost immedietly after I noticed I experience some pretty rough pain in my lower left jaw/ where the tooth is (furthest back left tooth) when i go to open my mouth further than speech level. I've been looking it up and most things say that's normal but I called the dentist and the receptionist made it seem pretty urgent and not normal and is having me come back today at 5. Now I'm extremely nervous, is that not normal despite everything saying it is? I'm going through dentologie so im kind of nervous that they don't even know what's going on since I've heard mixed reviews on denotologie.
