Question: What is the difference between a subluxated and a luxated tooth?
Explanation: A subluxated tooth has been loosened by trauma but has not moved out of its normal position. The periodontal ligament is stretched or partially torn, so the tooth feels slightly mobile and is tender to touch and biting. There may be bleeding from the gum margin. Crucially, the tooth still sits where it should. This is the mildest of the displacement injuries. Most subluxated teeth need no active treatment beyond a soft diet, monitoring, and sometimes a short-term flexible splint for comfort. The pulp usually survives, but follow-up is still needed.
Related Questions:
Does a subluxated tooth need any treatment?
Usually not beyond observation. A soft diet for a week and avoiding biting on the tooth allows the ligament to heal. If the mobility is uncomfortable, a flexible splint may be placed for up to two weeks. Follow-up checks at six to eight weeks are standard.
How do I know if my tooth is subluxated or just bruised?
Both present with tenderness after impact. The distinguishing feature is mobility. A concussed tooth is tender but firm. A subluxated tooth wobbles slightly when pressed. Bleeding from the gum crevice also points towards subluxation. A dentist confirms with clinical testing.
Can a subluxated tooth die later?
Yes, though it is less common than with severe luxations. Pulp necrosis can develop months after the injury. Warning signs include darkening of the tooth, a gum boil, or pain on biting. This is why follow-up appointments over the first year matter.
