What does this mean?
A tooth is suspended in the jawbone by fibres of connective tissue. That attachment allows a natural give of well under a millimetre. Movement you can see or feel with your tongue means the attachment, and the bone around it, has been lost.
How quickly the movement appeared is informative. Looseness that increases slowly over months usually means advanced gum disease. Looseness that appears within days and comes with pain suggests an abscess or trauma.
There are two usual causes, and both progress through bone loss. What separates them is whether there is pain and how fast the picture developed.
Likely causes
What helps at home?
- Do not wiggle the tooth with your tongue or finger; each movement strains the attachment further
- Avoid hard food on that side, but do not let the cleaning slip
- If you clench or grind, it should be assessed; the force wears down an already weakened attachment fast
- Looseness that appears within days or increases quickly
- Swelling, pain or discharge alongside the looseness
- Movement after a blow, or a tooth knocked out of position
- The tooth shifting position, or your bite changing
Frequently asked questions
- Can a loose tooth tighten again?
- Lost bone does not come back, but once the inflammation is stopped the movement can reduce somewhat. Where needed the tooth is splinted to its neighbours for support.
- Does a loose tooth always have to come out?
- No. The decision rests on how much bone remains and how much the tooth moves. Many teeth assessed early can be kept.
