FAQ on At-Home Teeth Whitening
Is Teeth Whitening Dangerous?
Teeth whitening is not dangerous if done according to the manufacturer's instructions (application time, duration of treatment...). In case of tooth and gum sensitivity, consult your dentist before starting.
What are the most effective products to whiten teeth?
Kits with trays and gel or strips containing hydrogen peroxide or carbamide peroxide offer the best results for at-home use. They are the closest to treatments performed in a dental office. For those with sensitivity, peroxide-free formulas are an excellent alternative.
Do teeth stay white for a long time after whitening?
The duration of the whitening effect depends on individual factors (dental hygiene, consumption of coffee, tobacco...). However, you should plan for regular touch-up whitening sessions to maintain bright white teeth over the long term.
