- A loose tooth needs extra support while the gum around it heals
- A thin wire or a strip of resin is bonded across it and its steadier neighbors
- That holds it still so it stops moving while healing happens
- It usually stays in place for weeks to months
- Once healed, the splint comes off, though it never treated what loosened the tooth
Who usually does it
general dentist. Done in general and periodontal offices.
One question worth asking
What loosened this tooth, and what happens after the splint comes off?
Splint bonded outside the teeth
D4321. The splint runs along the outside surface of the teeth.
Loose teeth are bonded to their neighbors with a thin wire or resin so they stay steady while the gums heal. The two codes differ by whether the splint is on the inside or the outside of the teeth.
A thin wire or a strip of resin is bonded across the loose tooth and its steadier neighbors so it stops moving while things heal. It can go on the tongue side, where it does not show, or on the outer side. A splint holds teeth still; it does not treat whatever loosened them. Most plans file this as Basic. What they actually pay varies by plan.
