Red painful gums
Red, painful gums may reflect plaque, trauma, ulcers, infection, hormonal change, or a reaction to an oral product.
The short answer
Red, painful gums can result from plaque inflammation, trauma, ulcers, infection, hormonal change, or a reaction to an oral product, so the cause determines treatment.
Why can inflamed gums look red and bleed?
Inflamed gingiva may look red and bleed because swollen tissue has more exposed small blood vessels. Local pain can also come from a sharp edge, trapped irritant, ulcer, or infection.
How can you soothe and clean painful gums?
Continue gentle brushing, clean between teeth carefully, and avoid tobacco, very hot foods, and products that sting. A dentist examines the gums, teeth, bite, and oral tissues.
When should painful, red gums be assessed?
Book an assessment when pain or redness persists, returns, or comes with bleeding, pus, bad taste, fever, or a loose tooth. Facial swelling or trouble swallowing needs urgent attention.
What should the dentist investigate in painful gums?
Ask whether the change is gingivitis, ulcer, trauma, or infection, and whether periodontal measurements or an X-ray are needed.
Frequently asked questions
Can symptoms alone identify the cause?
They suggest possibilities, but an examination and sometimes imaging establish the cause.
What treatment is usually considered?
Treatment is chosen after the dentist identifies the cause and the affected tissues.
