Why do my gums swell at night
Nighttime gum swelling can reflect plaque inflammation, food trapping, an erupting tooth, or an infection that needs examination.
The short answer
Gums that seem more swollen at night may be inflamed throughout the day, irritated by food or plaque, or affected by a tooth or gum infection. Lying down can make pressure and throbbing more noticeable, but the timing alone does not identify the cause.
What does swelling of the gum tissue mean?
Swelling is enlargement of gingival tissue caused by inflammation or fluid changes in the tissue. Local swelling around one tooth may follow trapped food, a cavity, a cracked tooth, a periodontal pocket, or an erupting wisdom tooth; widespread swelling more often points to plaque-related inflammation or another systemic factor.
How can you soothe and clean swollen gums at night?
Rinse gently with lukewarm water, brush the area with a soft brush, and clean between the teeth without forcing an object into the gum. Note the location, pain, bleeding, bad taste, fever, and triggers, and arrange an examination rather than repeatedly squeezing the swelling.
When does night-time gum swelling need prompt care?
Arrange prompt dental care if swelling is localised, returns, produces pus or a bad taste, or is accompanied by tooth pain. Seek emergency help for facial or neck swelling, fever, or difficulty breathing, swallowing, or opening the mouth.
How can the dentist tell whether a tooth is involved?
Ask whether the swelling is in the gum or coming from a tooth root, and whether pocket measurements or an X-ray are needed. Ask what treatment removes the cause and what signs would mean the infection is spreading.
Frequently asked questions
Why is the swelling worse when I lie down?
Pressure and throbbing can feel more prominent at rest, but a dental examination is needed to identify the underlying cause.
Should I pop a gum swelling?
No. Squeezing can injure tissue and does not remove decay, a pocket, or an infected tooth root.
