Polanight 16
Polanight 16 is an at-home tooth-whitening system using a 16% carbamide peroxide gel in a fitted tray, with results depending on the tooth and stain.
The short answer
Polanight 16 is a professional tooth-whitening gel containing 16% carbamide peroxide for use in a custom or compatible tray. Carbamide peroxide releases hydrogen peroxide, which oxidises some colour molecules in natural tooth structure.
How should Polanight 16 trays and gel be handled?
The gel is intended for natural teeth, and the clinician should provide instructions for tray fit, amount, wear pattern, and storage.
How will Polanight 16 affect teeth and restorations?
Whitening can affect natural enamel and dentine, but fillings, crowns, veneers, and bridges do not change shade in the same way. Yellow or brown surface stain may respond differently from intrinsic discolouration or a darkened tooth after trauma.
Sensitivity and gum irritation depend on concentration, contact, tray fit, wear time, tooth condition, and individual response.
When should you seek care before using Polanight 16?
Have the teeth and gums examined before use, clean the trays, place only the instructed amount of gel, and wipe away gel that contacts the gums. Follow the supplied wear schedule and stop if significant pain or tissue irritation develops.
Keep the gel sealed as directed and away from children. Do not combine it with other whitening products without professional guidance.
What should you do if Polanight 16 causes severe irritation?
Seek dental care for severe sensitivity, gum burns, cracked teeth, decay, or a single tooth that has darkened. An examination is also needed if the trays do not fit or whitening causes persistent symptoms.
Frequently asked questions
A 16% carbamide peroxide gel is a tray-based whitening material, not a treatment for decay or gum disease.
Only natural tooth structure changes shade with bleaching; restorative materials may need separate shade planning.
