How long do teeth whitening trays last
Whitening trays can remain usable when they keep their shape, but results fade as new stain develops and may need supervised touch-ups.
What is the direct answer?
Whitening trays can remain usable when they keep their shape, but results fade as new stain develops and may need supervised touch-ups.
What does this question mean?
Whitening changes tooth colour through a peroxide gel that diffuses through enamel and dentin. Trays do not whiten fillings, crowns, veneers, or other restorations, and the visible result changes as teeth acquire stain from food, drinks, tobacco, or ageing.
What can you do next?
Store the tray clean and dry in its case, away from heat, and bring it to review if it no longer seats. Use only the prescribed gel and wear time, because excess gel or a poor fit can irritate gingiva and increase sensitivity.
When should you seek dental care?
Stop using the tray and seek advice for persistent sensitivity, gum burning, ulcers, uneven contact, or a cracked appliance. A dental check is needed before whitening when decay, gum disease, or exposed roots are present.
What should you ask the dentist?
Ask whether the tray still fits, which teeth can respond, how restorations will appear, and what gel concentration and wear schedule are appropriate for your enamel and gums.
