I went into the dentist Monday and I was injected around 8:30 a.m now I'm still feeling symptoms today (Tuesday). I had 2 cavities filled in the right corner of my mouth and I felt my tongue go numb immediately. I was worried, but my dentist reminded me I had gone through that before, I just thought it felt different. I'm feeling some numbness and tingling on one side of my tongue, my lip and the rest of my face feel normal. I can feel my lips and the rest of my face. I called my DDS and he only works 2 days, and I can't get in during the one time that is available today so I have to wait until Friday. I'm worried, can anyone tell me why this is happening?
