Can you brush your teeth before using whitening strips?
Brush before whitening strips, but use a gentle technique and wait if brushing has irritated your gums.
Why does brushing first help whitening gel contact enamel?
Brushing first removes plaque so the whitening gel contacts the enamel more evenly. Vigorous brushing immediately beforehand can leave gums tender.
How do whitening strips deliver peroxide to tooth surfaces?
Whitening strips hold peroxide gel against the front enamel surfaces. They lighten some stain molecules, but do not change the colour of fillings, crowns, or veneers.
How should you prepare your teeth before applying the strips?
Use a soft brush and fluoride toothpaste, rinse, and dry the teeth lightly before applying the strips as directed. Keep gel off the gum margin and do not exceed the label schedule.
When should whitening side effects be assessed by a dentist?
Stop and arrange dental advice if strips cause persistent pain, ulceration, marked sensitivity, or whitening around an untreated cavity.
Frequently asked questions
What should I avoid?
Avoid irritants, forceful manipulation, and delaying an examination when symptoms persist.
Can home care cure the cause?
Home care may reduce irritation or pain briefly, but structural damage or infection needs treatment directed at its cause.
