Diagnose the cause
The first step is identifying whether looseness is from trauma, gum support, infection or bite pressure.
Loose tooth
A loose adult tooth can be linked with gum disease, trauma, bite pressure, infection or bone loss and should be assessed.

Why is my adult tooth loose?
A loose adult tooth needs context. Movement can come from gum disease, trauma, infection, bite pressure or bone support changes, and the right decision depends on the cause.
What you may be worried about
- The tooth may not be saveable.
- Movement may mean gum disease or bone loss.
- Biting may make the tooth worse.
Common patterns people notice
- loose tooth
- moving tooth
- bite change
Possible causes
- Gum disease and loss of supporting bone.
- Trauma, a fall or a knock to the tooth.
- Infection around the tooth or root.
- Heavy bite pressure, grinding or clenching.
When to treat this as urgent
Urgency level: soon
- The tooth became loose after a fall or accident.
- There is swelling, severe pain, pus or fever.
- The tooth has moved position or the bite has changed.
What to do now
- Avoid chewing heavily on the loose tooth and do not wiggle it repeatedly.
- Use urgent help if looseness followed trauma or comes with swelling, severe pain, pus or fever.
- Book an assessment soon if movement is new, changing or affecting biting.
What to avoid
- Do not test the tooth repeatedly with your tongue or fingers.
- Do not assume a loose adult tooth will tighten without understanding the cause.
When to arrange a dental assessment
- Arrange assessment if an adult tooth feels mobile, has changed position, hurts to bite on, or is linked with bleeding gums or trauma.
What a dentist may need to assess
- Gum and bone support, infection, trauma signs, bite pressure, X-rays, mobility level and whether the tooth can be stabilised.
Options that may be considered
Stabilise or treat
Some loose teeth may need support, gum treatment, infection management or bite adjustment.
Replacement planning
If the tooth cannot be predictably saved, replacement options can be discussed calmly.
What we would consider before recommending treatment
- Degree of movement and whether it is changing.
- Gum and bone support.
- Infection, trauma history and bite forces.
If it were our own teeth
If it were our own tooth, we would want to understand whether movement is reversible, manageable or a sign the tooth has a poor long-term outlook.
A sensible next step
Use the emergency dental page if looseness follows trauma or comes with swelling. Otherwise, book an assessment soon.
Possible next steps
- Gum treatment, bite adjustment, stabilisation, infection treatment, monitoring, extraction or replacement planning may be discussed.
