Teeth bleaching how long does it last
Teeth bleaching fades as new stains accumulate, and how long the colour change remains depends on diet, tobacco exposure, enamel, and the bleaching plan.
How long does teeth bleaching usually last?
Teeth bleaching fades as new stains accumulate, and how long the colour change remains depends on diet, tobacco exposure, enamel, and the bleaching plan.
Why can bleaching results differ between teeth?
Bleaching changes the colour of natural tooth structure, not fillings, crowns, veneers, or bonding; the visible result therefore depends on both tooth type and stain source.
How can you help your whitening results last?
Maintain brushing and interdental cleaning, follow the dentist’s retouching plan, and reduce repeated exposure to strongly pigmented foods, drinks, or tobacco.
When should a dentist assess a darkening tooth?
Ask for an assessment if one tooth darkens, sensitivity persists, or colour change follows trauma, because bleaching may not address the underlying problem.
What could be causing the tooth discolouration?
Is the discolouration caused by surface stain, internal tooth change, or a restoration, and which method matches that cause?
Frequently asked questions
Can this be diagnosed from a description alone?
A description helps identify possibilities, but examination and sometimes dental imaging are needed to distinguish them.
What should I avoid before the appointment?
Avoid squeezing, scraping, hard brushing, or changing prescribed dental appliances without clinical instructions.
