When patients experience some occlusal pain due to tooth decay, the time it takes for relief depends on the patient's inflammation levels and the treatment measures taken. If the patient receives timely treatment and effectively alleviates the inflammation, it generally takes about a week to heal and relieve the pain. If the patient does not undergo treatment, the condition may worsen and the pain may persist longer. Therefore, when a patient has tooth decay, it is best to visit a hospital for a consultation. Treatment should be administered based on the extent of the decayed tooth, and in severe cases of decay, tooth extraction might be necessary.
