Good evening! Can you please tell me urgently who treated teeth on the 6th week? Today my filling fell out and the tooth edge broke (but the root is standing), the tooth hurts, so there's a nerve ((it's impossible to take an X-ray). I went to different dental clinics today, nobody accepted me, only found one for tomorrow? What should I do???
