Swollen gum and loose tooth
A swollen gum beside a loose adult tooth can signal gum disease, infection, trauma, or loss of supporting bone.
The short answer
A swollen gum beside a loose adult tooth can signal gum disease, infection, trauma, or loss of supporting bone. The tooth needs an examination because mobility is a sign that the tissues anchoring it may be compromised.

What is the direct answer?
What does this question mean?
The tooth is held by the periodontal ligament and alveolar bone, while the gum forms a seal around it. Plaque-related inflammation can destroy attachment over time, but a sudden change can also follow a blow, bite overload, a root fracture, or an abscess.
What can you do next?
Brush gently with a soft brush, clean between teeth without forcing an object into the gum, and avoid chewing hard foods on that side. Do not wiggle the tooth or attempt to glue it; the dentist may remove deposits, adjust the bite, stabilize the tooth, or treat the pulp and gums according to the cause.
When should you seek dental care?
Book an urgent examination for rapid swelling, severe pain, fever, pus, a tooth displaced by injury, or a tooth that became loose suddenly. Breathing or swallowing difficulty, or swelling spreading into the face or neck, requires emergency care.
What should you ask the dentist?
Ask whether periodontal probing and dental X-rays show attachment or bone loss, an abscess, or a root fracture. Ask whether the tooth can be stabilized and what gum, bite, endodontic, or restorative treatment is needed.
Frequently asked questions
Can a loose adult tooth tighten again?
It may become more stable when inflammation or bite trauma is treated, but the outlook depends on the remaining attachment and the tooth's condition.
Should I pull out a loose tooth?
No. Removal should follow an examination because some teeth can be stabilized or treated.
