Working on Whitening Strips

If you are thinking that whitening strips work then you will get to know that these are thin, flexible plastic strips coated with a peroxide-based gel, usually hydrogen peroxide or carbamide peroxide, which is an active bleaching agent. When applied to teeth, these strips release oxygen ions that penetrate the enamel and dentin layers. These oxygen ions break down the molecular bonds that create stains on teeth, effectively whitening teeth.

Peroxide in the gel acts as an oxidizing agent, reacting with discolored molecules present in teeth. Most whitening strips must be applied daily for a set period, typically 5 to 30 minutes, for days to weeks, depending on the specific product and brightener concentration. It is essential to follow instructions carefully to achieve safe and effective results while minimizing the risk of sensitive teeth or gum irritation.
