The short answer
A white blister-like spot on the gum may be a canker sore, a small draining gum abscess, irritation, or another lesion, and its cause depends on its exact site and features.
Why might an abscess drain through a small gum opening?
The gum is soft tissue over the jawbone, while an abscess is infected fluid that can drain through a small opening near a tooth.
What should you do about a white spot on the gum?
Do not pop it; brush gently, rinse after meals, and note its duration, size, pain, and relation to a tooth.
When could a white gum blister need prompt care?
Seek prompt care for facial swelling, fever, worsening tooth pain, bad taste, or difficulty swallowing or breathing.
What should you ask about a white gum lesion?
Ask whether the lesion starts in the gum or tooth, whether an X-ray is needed, and what treats the cause.
