There are two possible reasons for waking up with swollen gums: first, it may be due to the patient’s poor periodontal condition, resulting in periodontal abscess or alveolar abscess, in which case the patient is advised to visit a periodontist in a timely manner. After performing periodontal abscess incision and drainage, then take appropriate anti-inflammatory drugs, such as amoxicillin and metronidazole. After the inflammation subsides, basic periodontal treatment is needed to remove the lesions in the mouth, such as intraoral calculus and plaque, etc. After removing the intraoral irritation, the swelling and pain will naturally subside. The second type of periodontitis may be caused by inflammation of the patient’s wisdom teeth. Pericoronitis may lead to pericoronary abscesses, etc. Patients are advised to go to the hospital for pericoronary abscess incision and drainage, followed by rinsing and medication. After that, you need to take 3-5 days of anti-inflammatory medication, and after the periapical abscess subsides, the wisdom tooth can be extracted.
