IPR (Interproximal Reduction): Filing Between Teeth
Filing 0.2–0.5 mm between teeth creates space without extraction. Here's how and why.
Dr. James Chen
Orthodontist
What it is
Using a fine disk or strip to remove 0.2–0.5 mm of enamel between specific teeth to create space for alignment.
Why it's done
- Avoids tooth extraction
- Creates space for crowded alignment
- Reduces width of oversized teeth
- Helps close black triangles
Is it safe?
Yes. Done within enamel thickness; no nerve involvement; doesn't weaken teeth.
Procedure
- Local anaesthetic usually not needed
- 5–15 minutes
- Painless
Long-term effects
- Minimal: teeth remain healthy
- Space created stays with movement
- No increased cavity risk
Alternative to IPR
- Extraction: more space but loses teeth
- Expansion: widens arch but limits
