Gel dessensibilizante UltraEZTM com Nitrato de Potássio e Flúor

The syringe makes it so easy to apply a thin, even layer right where the sensitivity is worst, and the potassium nitrate actually calms the ache within a few days. I've been through whitening trays that left my teeth screaming, but this gel let me finish the whole course without wincing.

The prefilled trays are a lifesaver for anyone who hates dealing with messy syringes—they fit comfortably and stay in place. My teeth feel noticeably less sensitive to cold air and water after just a few uses, and the fluoride is a nice bonus for protection.

Used the syringe version after my last cleaning and the sensitivity was gone by the next morning, which never happens with the stuff my dentist sells. The potassium nitrate really does the job without any weird aftertaste.
