After my first few weeks with clear aligners, it was time for the next step in my smile journey: interproximal reduction (IPR). I’ll admit, the name sounded a little intimidating at first, and I wasn’t sure what the appointment would involve. If you’re wondering whether IPR hurts or what actually happens, here’s my honest experience from my appointment at Urban Smile Hawthorn.

What is IPR & Why Did I Need It?
IPR, or Interproximal Reduction, is a technique used in clear aligner treatment to create tiny spaces between teeth. It’s especially helpful for:
- Minimizing black triangles (those little gaps between your teeth near the gums)
- Reducing crowding to allow teeth to align properly.
- Help relieve contact resistance between teeth which may hinder the movements.
- Creating space for better alignment without needing extractions
For me, IPR was scheduled at my 14th Aligner, as part of my treatment plan designed by Dr. Sarah Lawrence. Everyone’s timeline is different because each smile is unique, but my aligners had already moved my teeth to a point where IPR was the next step.
The IPR Process: What It Feels Like
I was a little nervous walking into the appointment. While I had heard it was a painless procedure, the idea of having my teeth filed made me a bit uneasy. Would it feel weird? Would I notice a difference right away? Those thoughts were running through my head, but I reminded myself that it was just another step toward my Dream Smile. Even though I’d seen a couple of IPR procedures before, I wasn’t sure what to expect firsthand. But Trish, my Oral Health Therapist, was amazing. She was extra gentle, probably because she knew I was a bit apprehensive.

Here’s what happened at my IPR appointment:
- Measurement & Planning – Trish checked my treatment plan and mapped out exactly how much IPR was needed.
- The Filing Process – Using a fine dental strip and a polishing tool, she created 0.4mm of space between four of my teeth and 0.3mm between a couple of others. That’s quite a bit, but it was necessary for my teeth to align properly.
- The Sensation – It didn’t hurt at all! The sound was the worst part. Imagine someone putting an ASMR microphone on a nail file—it’s that kind of subtle scraping noise. But no pain whatsoever!
- Post-IPR Feeling – My teeth were a little tender from the motion, but not more than when I put in a fresh set of aligners.
My Smile Progress So Far
I’m now three-quarters of the way through my first set of aligners, and the transformation is incredible. In just 3.5 months, my smile is already looking amazing, and I’ve had so many compliments from friends and family. It’s exciting to think about how straight my teeth will look once I complete my refinement set of aligners!
Final Thoughts: Should You Be Nervous About IPR?
If you have IPR coming up as part of your clear aligner treatment, don’t stress! It’s quick, painless, and over before you know it. The benefits far outweigh any momentary discomfort, and the team at Urban Smile make the experience as smooth as possible.
