What can a swollen lump beside one tooth indicate?
Swollen gums often reflect plaque-related inflammation, but a lump beside one tooth can also indicate trapped food, decay, or infection.
The appropriate response depends on the condition found in the teeth, gums, or supporting tissues.
What does the gum’s position around teeth help explain?
The gingiva surrounds teeth and covers the jaw. Widespread puffiness commonly follows plaque, while one-site swelling may involve food impaction, an erupting tooth, a cracked tooth, or infection from the pulp or supporting tissues.
The anatomy involved explains why some home measures help symptoms while other problems need clinical treatment.
How should you clean a swollen gum lump safely?
Clean gently with a soft brush and interdental aid, and do not puncture or squeeze a lump. Examination may include probing, pulp tests, and a focused radiograph before cleaning, drainage, filling, root canal treatment, or extraction.
Note when the problem occurs, what changes it, and which products or medicines you have already used.
When should a dentist examine a persistent gum lump?
Book promptly for persistent swelling, bleeding, bad taste, pain on biting, or drainage. Facial swelling, fever, restricted opening, or trouble swallowing or breathing requires urgent care.
An examination distinguishes irritation from disease affecting the tooth, pulp, gum, or supporting bone.
How can the dentist identify where the swelling begins?
Ask whether the swelling is in the gum or around the root, and which examination or radiograph is needed before treatment.
Ask how the recommended treatment addresses the cause and which changes should prompt a review.
