What is the direct answer?
HiSmile whitening results are temporary because whitening does not prevent new stains from forming, and duration depends on the treatment and your habits.
What does this question mean?
HiSmile products may use peroxide or other whitening ingredients depending on the kit. Whitening does not change the colour of fillings, crowns, veneers, or dentures.
What can you do next?
Follow the product instructions, never leave material on longer than directed, and stop if significant sensitivity or gum irritation develops. Maintain brushing and interdental cleaning.
When should you seek dental care?
See a dentist before repeating whitening if teeth hurt, enamel is damaged, gums are inflamed, or restorations are visible. Seek care for persistent sensitivity or chemical burns.
What should you ask the dentist?
Ask what type of staining you have, whether the product suits your enamel and restorations, and how to manage sensitivity.
Frequently asked questions
Can home care replace an examination?
Home care may provide temporary comfort, but it cannot diagnose or remove the dental cause.
What should I bring to the appointment?
Bring medicine details, relevant health conditions, symptom timing, and details of products or treatment used.
