Why are my gums swollen and what should I do?
Generalised puffiness along the gum line is most often plaque-related inflammation, while a swelling at one spot may point to a trapped food particle, a gum abscess or an infected tooth. Rinse gently with warm salt water and keep the area clean, but have it examined — the treatment for each cause is different, and only an examination can tell them apart.
Common causes
- Plaque-induced gingivitis inflaming the gum margins
- A gum or tooth abscess creating a localised, often tender swelling
- Food or a foreign particle (like a popcorn husk) lodged under the gum
- A partially erupted wisdom tooth with inflamed overlying gum (pericoronitis)
- Hormonal changes during pregnancy or puberty exaggerating gum response
- Certain medications, such as some blood pressure and epilepsy drugs, causing gum overgrowth
- Irritation from a rough filling edge or an ill-fitting denture clasp
Warning signs to watch for
- Swelling that lasts more than a few days or keeps returning in the same spot
- Throbbing pain, or a pimple-like bump on the gum that leaks fluid
- Swelling spreading to the face, jaw or under the eye
- Fever or feeling unwell along with the gum swelling
- Bleeding from the swollen area at the lightest touch
When should you see a dentist?
Mild, generalised puffiness can be watched for a few days while you improve cleaning at home — if it persists beyond that, book a check-up. A localised swelling that is painful, growing, or discharging should be seen within a day or two. Seek urgent care immediately if gum swelling is accompanied by facial swelling, fever, or any difficulty swallowing or breathing, as spreading dental infections need prompt management.
How it is diagnosed
Dr Shantanu Rao will examine the swelling, check whether it is soft, firm or fluid-filled, and test the nearby teeth for tenderness and vitality. Gum pocket measurements show whether the swelling arises from the gum itself, and an X-ray of the area is taken when an abscess or a problem inside a tooth is suspected — the source is not always the tooth nearest the swelling.
Possible treatment directions
Treatment follows the cause found on examination. Directions a dentist may consider include:
- Professional cleaning and improved home care for plaque-related swelling, sometimes followed by deep cleaning below the gum line.
- Drainage and cleaning of a gum abscess, with removal of whatever caused it.
- Root canal treatment where the swelling traces back to infection inside a tooth.
- Adjusting or replacing a rough restoration or denture edge that is irritating the gum.
- A medication review with your physician if drug-related gum overgrowth is suspected — never stop prescribed medicines on your own.
What can happen if it is ignored
Plaque-related swelling that is ignored tends to advance the same way untreated gingivitis does — towards deeper gum disease. A localised infected swelling is the bigger concern: an abscess does not resolve permanently on its own, and pressure or infection can spread to surrounding tissues over time. Persistent or recurring swelling is your body flagging an unresolved source, and finding that source early keeps treatment simple.
Frequently asked questions
Will salt water rinses cure swollen gums?
Warm salt water soothes the tissue and helps keep the area clean, which is useful first aid. It does not remove tartar, drain an abscess, or fix an infected tooth — so if swelling lasts beyond a few days, an examination is still needed.
My gum swells around the same tooth every few weeks. Why?
A recurring swelling in one spot usually means a persistent source — a deep gum pocket, a crack, or infection inside the tooth. Each flare may settle, but the cause remains until it is diagnosed and treated.
Are swollen gums during pregnancy dangerous?
Pregnancy gingivitis is common and usually settles with good cleaning and professional care. Occasionally a harmless overgrowth called a pregnancy epulis appears. Both should still be reviewed by a dentist rather than assumed.
Should I take antibiotics for a gum swelling?
Antibiotics alone rarely solve dental swellings, because the source — trapped debris, a pocket or an infected tooth — remains. They are used selectively alongside definitive treatment, and only when a dentist judges them necessary.
