Why are my bottom gums irritated
Bottom-gum irritation commonly reflects plaque, friction, dryness, or inflammation around teeth and should be checked if it persists.
The short answer
Bottom-gum irritation commonly reflects plaque-related gingivitis, brushing or flossing trauma, food impaction, a mouth ulcer, dry mouth, or a dental appliance rubbing the tissue.
What signs can appear on the lower gums?
The lower gums may look red, feel tender, bleed during cleaning, or swell around one tooth. A dentist distinguishes surface irritation from gum disease, decay, a cracked tooth, or an abscess by examining the gum margin and tooth.
How should you care for irritated lower gums?
Use a soft brush with gentle pressure, clean between the teeth once daily, and rinse with plain water after food. Avoid tobacco, very hot foods, and aggressive scrubbing while you watch the area.
When should lower-gum irritation be examined?
Arrange a dental examination when irritation lasts, recurs, or is accompanied by bleeding, recession, pus, tooth sensitivity, or a loose tooth. Seek urgent help for facial swelling, fever, or difficulty swallowing or breathing.
What should the dentist check in the lower gums?
Ask whether plaque or tartar is driving the inflammation and whether the tooth has decay or a pocket. Ask for advice on brushing pressure, interdental cleaning, and any adjustment needed for a retainer or denture.
Frequently asked questions
Should I stop brushing irritated gums?
No. Continue gentle cleaning because plaque can prolong inflammation, but use a soft brush and light pressure.
Why is only one lower gum sore?
A single site can be affected by trapped food, a rough filling, a cracked tooth, or a local periodontal pocket.
