Since your socket is filled with blood, there is nothing to worry much. Regarding this socket, I cannot assure you without seeing the image. Maintain your oral hygiene and follow the instructions given by your dentist. Do warm salt water gargling after a day and for the next 24 hours do not gargle forcefully or spit forcefully. Do not consume anything very hot and do not use straws for drinks. Do not try to manipulate the area with tongue or finger. All the other instructions would have been given by your dentist.
Dry socket is diagnosed after two to three days with the patient symptoms only. But in case, if you have any bad odor or pain or bad taste, you can visit your dentist. Do a sedative dressing and medication will be given. Do not worry. You will be fine. Just adhere to the instructions correctly. Take your medicines properly, if the antibiotics are given.
