Relief ACP

Relief from tooth sensitivity

Relief ACP is the only FDA-cleared dual-action sensitivity relief product available. Its proprietary formula combines the speed of chemical sensitivity relief from potassium nitrate with the profound, long-term relief of amorphous calcium phosphate and fluoride, which precipitates hydroxyapitite and fluorapatite, occluding the dentin tubules. This highly effective formula is ideal for patients who suffer from tooth sensitivity caused by gum recession, root exposure, post root planning, and whitening.

Understanding ACP

ACP (amorphous calcium phosphate) is a revolutionary technology that is licensed exclusively to Philips Oral Healthcare in the field of professional whitening by the ADA Foundation. Whitening with ACP means stronger teeth, greater comfort, better results and optimal compliance by your patients. Relief ACP comes with all Philips Zoom take-home kits and can be used as treatment several times daily by everyone, as it has no known allergens.

Benefits of ACP


  • Rebuilds enamel: The deposition of hydroxyapatite onto teeth rebuilds enamel and restores luster through the remineralization process.


  • Reduces sensitivity: Clinical tests comparing Philips Zoom NiteWhite ACP with a NiteWhite formula containing no ACP showed that 30% of patients who used NiteWhite with ACP experienced less sensitivity, with twice as many patients experiencing zero sensitivity.


  • Improves appearance: Tooth whiteners with ACP also improve the cosmetic appearance of teeth by restoring enamel luster to create a smoother, glossier appearance.
