Frequently asked questions about HiSmile
How long do HiSmile’s products take to whiten teeth?
For the best results, the full course takes around 14 days, depending on the product and how often it is used.
Is HiSmile safe for sensitive teeth?
Yes, HiSmile products are designed to be peroxide-free or use gentle whitening ingredients, making them suitable for many people with sensitive teeth.
Does HiSmile work on veneers, crowns, or fillings?
HiSmile’s products are designed to whiten natural tooth enamel only. They will not change the colour of veneers, crowns, fillings, or bonding.
How often should I use HiSmile whitening products?
Whitening treatments should be used once daily during the initial whitening period. After achieving the desired shade, you can switch to occasional top-ups or use whitening oral care products.
How long do the whitening results last?
This depends on your diet and oral hygiene habits, as these can shorten the lifespan of results. If you maintain good oral hygiene and follow a balanced diet, results can last several months or longer.
