Filing Between Teeth in Orthodontics: How Interproximal Reduction (IPR) Creates a Better Smile
When undergoing orthodontic treatment, some patients may need filing between teeth to create small spaces for better alignment. This process, known as interproximal reduction (IPR), is a safe, conservative, and effective technique used to improve tooth proportions, correct spacing, and enhance overall smile aesthetics.
At Elate Orthodontics, we use filing between teeth as a minimally invasive alternative to extractions, allowing for better alignment and long-term stability in orthodontic treatment.
What Is Filing Between Teeth (Interproximal Reduction)?
Filing between teeth, also called interproximal reduction (IPR), slenderizing, or enamel reshaping, is a procedure where a tiny amount of enamel (usually less than 0.5 mm per tooth surface) is carefully removed to:
✔ Create space for crowded teeth – Helps align teeth properly without extractions.
✔ Correct tooth size discrepancies – Ensures proportional alignment between upper and lower teeth.
✔ Reduce black triangles – Eliminates small gaps that can appear near the gum line after treatment.
✔ Improve smile aesthetics – Creates a smoother and more natural-looking alignment.
✔ Enhance stability after treatment – Helps prevent teeth from shifting after orthodontic care.
This conservative approach is especially useful for patients using clear aligners or braces where small adjustments in space can significantly improve alignment.
Is Filing Between Teeth Safe?
Yes! Interproximal reduction is a safe and well-documented technique in orthodontics. The amount of enamel removed is minimal and does not make the teeth more prone to cavities or sensitivity when performed correctly.
At Elate Orthodontics, we ensure that IPR is done with precision and care, preserving your dental health while achieving optimal alignment.
✔ No increased risk of cavities – IPR removes only a thin layer of enamel, and proper hygiene keeps teeth strong.
✔ No pain or discomfort – The procedure is painless and does not require anesthesia.
✔ No long-term damage – The enamel remains thick enough to protect against decay and wear.
Why Is Filing Between Teeth Necessary?
In many orthodontic cases, teeth need small adjustments to fit together perfectly. Instead of removing teeth, filing between teeth (IPR) offers a conservative solution to improve alignment while keeping all natural teeth intact.
1. Creating Space for Crowded Teeth
If teeth are slightly crowded, IPR provides enough space to align them correctly without needing extractions. This is common in patients with mild to moderate crowding.
2. Correcting Tooth Size Discrepancies
Some patients have naturally disproportionate teeth, where the upper and lower teeth don’t align properly. Filing between teeth ensures that both arches fit together harmoniously.
3. Eliminating Black Triangles Between Teeth
Black triangles—small gaps that appear between teeth near the gums—can be corrected with precise reshaping of enamel to create a more uniform look.
4. Avoiding Tooth Extractions
In some cases, patients may need extra space for their orthodontic treatment to work effectively. Instead of removing permanent teeth, filing between teeth provides a minimally invasive alternative.
How Is Filing Between Teeth Done?
There are several methods for performing interproximal reduction (IPR):
✔ Hand Stripping – A fine, flexible strip is used to gently polish and remove small amounts of enamel by hand.
✔ Mechanical Reduction – A specialized orthodontic tool is used to precisely and evenly remove enamel between teeth.
✔ Disc Reduction – A small polishing disc is used for more uniform reduction in cases that require more space.
All of these techniques are painless and minimally invasive, ensuring a smooth and comfortable experience.
What to Expect After Filing Between Teeth
After interproximal reduction, patients may notice:
✔ Smoother tooth surfaces – The reshaped areas will feel polished and natural.
✔ Temporary small gaps – These spaces gradually close as treatment progresses.
✔ No pain or sensitivity – Since enamel is only slightly reduced, discomfort is minimal.
There is no special aftercare required—patients can continue normal brushing, flossing, and dental care routines.
Filing Between Teeth vs. Tooth Extractions: Which Is Better?
For many patients, IPR is a better alternative to extractions because it:
✔ Preserves all natural teeth – No extractions are required.
✔ Maintains a natural-looking smile – Teeth retain their original proportions while aligning properly.
✔ Reduces overall treatment time – Small adjustments allow for faster tooth movement.
However, in severe crowding cases, extractions may still be necessary. At Elate Orthodontics, we carefully evaluate each patient’s needs to determine the best approach for a successful orthodontic outcome.
Is Filing Between Teeth Right for You?
If you’re undergoing orthodontic treatment with braces or clear aligners, filing between teeth (IPR) may be recommended to help achieve the best possible results. It’s a safe, painless, and minimally invasive technique that improves smile aesthetics and long-term stability.
