NA ORTHODONTICS

Interproximal Reduction (IPR)—also called “tooth slenderizing”, “stripping” or enamel reduction is a precise orthodontic technique where a fraction of a millimeter of enamel is smoothed  between teeth to reshape teeth and/or create just enough space for alignment. We use ultra-fine polishing strips or a handpiece to make tiny, carefully planned adjustments that improve both alignment and esthetics.

While IPR has several applications, at NA Orthodontics we focus on using IPR where is adds the most patient benefit:

• Black-triangle reduction is the main reason we IPR at NA Orthodontics. 

• Improves esthetics by refining tooth shape and proportions

• Better gum and bone health by reducing plaque and food traps.

• Create space without extractions in patients with severe crowding (used sparingly as expansion and bite correction usually create the needed space needed)

• Bite refinement during Invisalign® or braces, especially when tooth size proportions are mismatched

Yes. IPR is a safe procedure. Our orthodontists are conservative with IPR and make sure your enamel stays healthy and strong. Enamel has a safe reduction range and we keep well within biologically safe ranges. We polish IPR surfaces so your teeth remain smooth and easy to clean.

Typical IPR ranges from 0.1– 1 mm per contact, about the thickness of a business card. The exact amount depends on tooth shape and enamel thickness. 

Most patients feel little to no discomfort. Anesthesia is not needed and sensitivity is rare.

• “IPR needs to be done.” We never insist on it and only recommend IPR if it benefits your smile, bite or gum health.

• “IPR weakens teeth.” Within safe limits, enamel remains strong and cavity-resistant.

• “It’s shaving teeth down.” No. IPR is done between the teeth and not on top. Teeth do not get shorter.

• “It causes cavities.” Smooth, polished contacts are not more cavity-prone with normal brushing and flossing.

You may benefit from IPR if you have:

• Black triangles between teeth

• Triangular or mismatched tooth shapes

• Crowding that doesn’t require extractions

• Bite discrepancies that align better with small enamel adjustments

At NA Orthodontics, we treat IPR as a precision tool, never a routine.

• We like to call it strategic IPR. We carefully plan where and when IPR can be used to maximize our patients’ oral health and esthetics.

• Expert clinicians: Dr. Jessica Greenberg (clinical faculty at the University of Pennsylvania) and our team plan IPR using 3D digital imaging and precise measuring tools.

• Esthetics focus: Straight teeth look best when shaped and proportioned correctly. We use IPR to fine-tune smiles

• Convenience: Most IPR sessions take only a few minutes and are done within your regular orthodontic visits.

• Two convenient locations: Jersey City and North Arlington, serving Bergen, Hudson, and Essex Counties.

Will IPR change how my teeth look?

• Yes, in a positive way. Tiny adjustments can reduce black triangles and improve tooth proportions.

Can IPR fix black triangles?

• Often, yes. Reshaping contact points encourages gum tissue to fill spaces naturally

Is special maintenance required?

• No. With normal brushing, flossing, and dental checkups, teeth remain strong and healthy.
