When it comes to creating beautifully aligned smiles, orthodontic treatment is about much more than simply straightening teeth; it’s about achieving the right balance, spacing, and long-term stability. One technique that often plays an important role in this process is Interproximal Reduction (IPR).
At Winthrop Orthodontic Centre, Dr Gordon Cheung and Dr Naomi Kohan use modern, evidence-based techniques like IPR to help patients achieve optimal results with both braces and clear aligners.
What is Interproximal Reduction (IPR)?
Interproximal Reduction, commonly referred to as IPR, is a precise orthodontic procedure that involves removing a very small amount of enamel from between the teeth. This creates tiny amounts of space that can help guide teeth into better alignment.
The amount of enamel removed is typically fractions of a millimetre and is carefully planned to ensure both safety and effectiveness.
Why is IPR used?
IPR is a versatile tool that orthodontists may recommend for several reasons:
1. To create space without removing teeth
In cases of mild to moderate crowding, IPR can create the space needed to align teeth properly, occasionally avoiding the need for extractions.
2. To improve tooth alignment
By making subtle adjustments to spacing, IPR allows teeth to move more predictably into their ideal positions.
3. To enhance smile aesthetics
IPR can help reshape slightly uneven or bulky tooth surfaces, leading to a more balanced and symmetrical smile.
4. To reduce black triangles
Small gaps near the gum line (known as “black triangles”) can sometimes appear after alignment. IPR can help minimise these spaces by improving how teeth contact each other.
Is IPR safe?
Yes,when performed by a specialist orthodontist, IPR is a safe and controlled procedure. The outer enamel layer is reduced only slightly, and always within safe limits that maintain the health and strength of the teeth.
At Winthrop Orthodontic Centre, advanced tools and precise planning ensure that IPR is carried out comfortably and effectively.
Does IPR hurt?
Most patients find IPR to be quick and painless. Because only the enamel surface is involved (which does not contain nerves), there is typically no discomfort. Some patients may feel slight pressure or vibration during the procedure, but it is generally very well tolerated.
How much enamel is removed?
The amount of enamel removed during IPR is very small, usually between 0.2 mm and 0.5 mm per contact point. To put this into perspective, enamel is the hardest substance in the human body, and this level of reduction is carefully calculated to remain well within safe limits.
Will I notice a difference after IPR?
In most cases, patients don’t notice any visible difference after IPR. The changes are subtle but play a significant role in helping teeth align more effectively.
Your orthodontist will always explain why IPR is recommended as part of your personalised treatment plan.
Is IPR right for everyone?
Not every patient will require IPR. It depends on factors such as:
- The level of crowding
- Tooth size and shape
- Your bite and overall treatment goals
During your consultation, Dr Gordon Cheung and Dr Naomi Kohan will assess your smile and determine whether IPR is beneficial for achieving the best possible outcome.
Interproximal Reduction is a conservative, precise, and highly effective technique used in modern orthodontics to create space, refine alignment, and enhance overall results. When used appropriately, it can make a significant difference in both the efficiency and outcome of your treatment.
