What is the direct answer?
NiteWhite ACP is a take-home tooth-whitening system using a peroxide gel in custom trays, with ACP referring to an added mineral ingredient.
What does this question mean?
A dentist or dental team provides trays that hold gel against the natural teeth. The gel releases peroxide, which breaks down stain molecules; fillings, crowns, and veneers do not whiten in the same way.
What can you do next?
Use only the prescribed amount in well-fitting trays and wipe away gel that reaches the gums. Store the gel as directed, keep it away from children, and follow the wear schedule supplied for your formulation.
When should you seek dental care?
Pause use and contact the dental team for marked sensitivity, gum irritation, a tray that cuts tissue, or a tooth that becomes painful. Decay, cracks, and inflamed gums should be assessed before whitening.
What should you ask the dentist?
Ask which gel strength and wear time were prescribed, how trays should be cleaned, and whether restorations will need later colour matching. Ask what to do if gel leaks onto the gums or sensitivity develops.
Frequently asked questions
Can I use extra gel for faster whitening?
No. Excess gel can spill onto gum tissue and increase irritation without making the treatment plan appropriate.
Why do my teeth become sensitive during tray whitening?
Peroxide can temporarily stimulate dentine pathways, particularly where enamel is thin or roots are exposed.
