How long does whitening gel last
Whitening gel is active only while its peroxide is breaking down, while the lightened shade can fade as new stains accumulate.
What is the direct answer?
Whitening gel is active only while its peroxide is breaking down, while the lightened shade can fade as new stains accumulate.
What does this question mean?
Carbamide or hydrogen peroxide breaks down into reactive oxygen compounds that alter colored molecules. The gel is used during its instructed treatment period and should not be reused past its storage or expiry directions.
What can you do next?
Follow the product storage and application instructions, reduce frequent staining exposures, and have sensitivity or uneven color checked before a touch-up.
When should you seek dental care?
Seek care for persistent sharp sensitivity, gum burns, pain, or darkening in one tooth.
What should you ask the dentist?
Ask which peroxide strength and tray fit are appropriate, how the gel should be stored, and whether restorations will match.
