Gums are red at the bottom
Redness along the lower gumline commonly reflects plaque inflammation, but trauma, recession, calculus, or infection can look similar.
The short answer
Red gums along the lower tooth margins most often indicate inflammation from plaque, although brushing trauma, calculus, recession, or a tooth-related infection can produce similar redness. The pattern, bleeding, tenderness, and condition of nearby teeth help distinguish the causes.
What is the direct answer?
What does this question mean?
The lower gumline is where the gingival margin meets the enamel or exposed root. Plaque bacteria can trigger gingivitis there; hardened calculus cannot be brushed away and can maintain inflammation, while a sharp tooth edge or vigorous brushing can injure the tissue.
What can you do next?
Brush twice daily with a soft brush angled toward the gumline and clean between the teeth. Avoid scrubbing, smoking, and picking at the area, and arrange a professional cleaning if deposits feel hard or rough.
When should you seek dental care?
Arrange an examination if redness lasts, bleeds repeatedly, causes bad breath, or occurs with gum recession or loose teeth. Urgent care is needed for spreading swelling, fever, pus, or severe tooth pain.
What should you ask the dentist?
Ask whether the redness is gingivitis, periodontitis, abrasion, a periodontal abscess, or irritation from a restoration. Ask for gum measurements and advice on the brush, interdental method, and cleaning interval suited to you.
Frequently asked questions
Can red gums heal with brushing?
Mild plaque inflammation may improve with consistent gentle cleaning, but calculus or deeper disease requires professional assessment.
Why is redness only around one tooth?
A trapped food particle, calculus, restoration edge, trauma, or localized infection can affect one area.
