My gums swelled up
Swollen gums can result from plaque-related gingivitis, food trapped under the gum, infection, irritation, hormones, or a medicine.
The short answer
Gum swelling is enlargement or puffiness of gingival tissue and may affect one area or the whole mouth.
Why can inflamed gums look red and puffy?
Inflamed gingiva can look red, feel tender, bleed during brushing, and become puffy where bacterial plaque collects at the gum margin.
How can you care for gums that have swelled up?
Brush gently twice daily, clean between the teeth, rinse away food debris, and arrange an examination rather than relying on mouthwash alone.
When is swollen gum tissue an urgent concern?
Get urgent dental help for facial swelling, fever, pus, severe pain, trouble swallowing, or reduced mouth opening; persistent swelling also needs evaluation.
Could the swelling be limited to gingivitis?
Is the swelling limited to gingivitis, or is there infection around a tooth?
Frequently asked questions
What is the most likely cause?
The cause depends on the location, duration, examination findings, and any dental treatment already done.
Can I manage this at home?
Gentle cleaning and avoiding irritation may help temporarily, but persistent or worsening symptoms need clinical assessment.
