Girls good day! Ten days ago I started having nausea, couldn't brush my teeth in the morning, they advised me to clean later - it helped. There is no nausea, only spasms can be and during the day and evening. Yesterday began to hurt tooth ??, I understand that you shouldn't delay and go to the dentist, but how do I imagine sitting for an hour with an open mouth in such a state ???. Maybe if there are some ways to block the urge to vomit? Water with lemon and ginger don't help. How can I go to the doctor safely?
