Day white acp 14 hydrogen peroxide
Day White ACP systems use a peroxide whitening gel with a calcium-phosphate ingredient, and the instructions determine exposure and irritation risk.
The short answer
Day White ACP systems use a peroxide whitening gel with a calcium-phosphate ingredient, and the instructions determine exposure and irritation risk. The tray should hold gel against the intended tooth surfaces without covering the gums.
How does peroxide break down tooth staining?
Hydrogen peroxide or carbamide peroxide releases reactive oxygen that breaks down some stain molecules within enamel and dentine. Amorphous calcium phosphate is used in some formulations to support mineral management during the whitening process.
How should you apply whitening gel safely?
Use only the amount placed in the prescribed tray and wipe away gel that reaches the gums. Do not extend wear time or combine products, and pause if burning, ulceration, or marked sensitivity occurs.
When should you have an examination before whitening?
Arrange an examination before whitening if you have untreated decay, cracked teeth, gum inflammation, exposed roots, or leaking restorations. Seek care for persistent sensitivity or a chemical burn after use.
Will peroxide whitening suit your tooth discolouration?
Ask whether the discoloration can respond to peroxide and whether the trays fit your gumline. Ask how to manage sensitivity and how crowns, veneers, and fillings will compare with the whitened teeth.
Frequently asked questions
What does ACP mean in a whitening product?
It refers to amorphous calcium phosphate, an ingredient included in some formulas alongside peroxide.
Why are my gums white after whitening gel?
Peroxide gel contacting gum tissue can irritate it temporarily; remove the gel and seek advice if the change persists or hurts.
