My husband had a deep filling in his upper second to last molar (left side). About several hours later, he started having discomfort and taking Tylenol and Ibuprofen interchangeably. Now, it has been the second day with severe pain and his cheek is swollen. And the gum over the tooth is in pain but not swollen, and it is a throbbing type of pain. We have no access to the dentist. Please help.
