There are many reasons why white spots just happen to come back after tonsil surgery. It could be the white membrane formed after surgery, or it could be Candida albicans infection, suppurative inflammation and so on. 1. Postoperative white film: after removing the tonsils, the wound will form a white film in 48 hours. 2. Candida albicans infection: Oral infection with Candida albicans can cause thrush, so there will be dots and flakes of white patches in the mouth, resulting in the phenomenon of white spots that just happen to rise again after tonsil surgery. 3. Purulent inflammation: If purulent infection occurs in the wound after tonsil surgery, it can induce inflammation, which leads to the phenomenon of white spots just after tonsil surgery. After the appearance of the above symptoms, it is recommended that patients go to the hospital in a timely manner to improve the examination, in accordance with the doctor’s instructions to take standardized treatment, not private treatment, so as not to lead to adverse consequences.
