i got my tooth extracted last friday and its my first time. i still have disconfort after 4 days and the hole looks empty. it doesnt have the whitish layer like i have read in several articles. is that normal or should i get that checked? also i have a weard taste in my mouth. is that normal too? also ppl tell me not to chew on that side of extraction but i kind of have no choice because on the other side i have a cracked molar that needs a root canal and its painful when i chew on that side. so what should i do with my case?
