Gum health and gum disease causes and triage
Healthy gums fit closely around teeth; persistent bleeding, redness, swelling, recession, or looseness can indicate gum disease.
The short answer
Gum disease begins when bacterial plaque inflames the gum margin and can progress from gingivitis to periodontitis, where inflammation damages the tissues and bone supporting teeth.
How does gum disease develop from plaque inflammation?
Gingivitis affects the gum tissue and may cause redness, swelling, and bleeding. Periodontitis involves periodontal pockets and loss of attachment around teeth, so the disease can continue with little pain while support is reduced.
What changes can gingivitis cause in the gums?
Gingivitis affects the gum tissue and may cause redness, swelling, and bleeding. Periodontitis involves periodontal pockets and loss of attachment around teeth, so the disease can continue with little pain while support is reduced.
What can you do when bleeding or swelling persists?
Brush twice daily with a soft brush, clean between teeth, avoid tobacco, and arrange professional assessment if bleeding or swelling persists. A dental team measures gum pockets, checks bleeding and tooth mobility, and may take radiographs.
Which gum changes need prompt dental assessment?
Seek dental care for ongoing bleeding, bad breath with gum changes, pus, gum recession, loose teeth, or a change in how teeth meet. Facial swelling, fever, or difficulty swallowing needs urgent attention.
What should you ask about gum pockets and bone loss?
Ask whether you have gingivitis or periodontitis, what your pocket measurements show, whether bone loss is present, and which home-care and professional treatment steps are needed.
Frequently asked questions
Can gum disease hurt?
It can cause tenderness, but significant disease may produce little pain, so symptoms alone cannot measure severity.
Can bleeding gums improve?
Bleeding may improve when plaque control and professional treatment address the inflammation, but the cause should first be identified.
