Side gum swollen
Localized gum swelling may come from trapped plaque, irritation, gum disease, an erupting tooth, or infection around a tooth.
The short answer
Swelling beside one tooth needs an examination because it may be gum inflammation, trapped debris, decay, or infection.

How can a dentist locate the source of gum swelling?
A dentist checks the gum pocket, tooth surface, bite, pulp response, and sometimes an x-ray to locate the source.
What can you do safely for swelling beside a tooth?
Brush gently, clean between teeth, and rinse with warm water. Do not pierce the swelling or put aspirin on the gum.
When does swelling beside a tooth need urgent care?
Seek urgent care for spreading swelling, fever, facial swelling, pus, or difficulty opening the mouth, swallowing, or breathing.
What should you ask about the swelling and any imaging?
Ask whether the swelling is in the gum pocket or linked to the tooth root, and whether imaging is needed.
