What does “Interproximal enamel stripping” mean?
In orthodontics, stripping means adjusting some enamel between neighbouring teeth to create space for alignment or refine tooth shape. It is also called interproximal reduction, or IPR, and differs from extracting a whole tooth.
Plan it according to diagnosed space and shape needs
It may be considered when a small amount of space is lacking for alignment or tooth shape needs adjustment. The teeth and enamel must be examined directly to plan which teeth need adjustment and to what extent. The same amount should not be prescribed for everyone from photographs alone.
Consider enamel removal and surface finishing together
Excessive enamel removal can harm dental health. If treated surfaces are not finished smoothly, plaque can accumulate more readily, making cleaning and care important. Understand the expected benefit, risks and alternatives before deciding; do not file teeth with tools yourself.
Review sensitivity, hygiene and subsequent tooth movement
Temporary sensitivity to cold foods or drinks may occur after the procedure, so ask about what to expect and how to care for the teeth. Report persistent discomfort to the team. Also confirm how the space will be used for movement and how alignment and retention will proceed.
Frequently Asked Questions
Is stripping different from interproximal reduction?
In orthodontics, the terms describe the same concept. The actual teeth, reason, extent of removal and alternatives matter more than the name.
Can everyone avoid extractions by filing a little between teeth?
No. The space available and the condition of the teeth and supporting tissues impose limits. Suitability and alternatives, including extractions, must be compared in relation to the whole bite and goals.

Why is enamel being adjusted between these teeth?
Explanation and evidenceAsk about the space or shape needed and current tooth condition, then confirm the planned extent and alternatives such as extractions or other orthodontic approaches.

How are the surfaces, sensitivity and hygiene managed afterwards?
Explanation and evidenceDiscuss surface finishing, cleaning, contact arrangements for persistent discomfort, planned movement into the space and later retention.
