Clarismile whitening
At-home whitening results depend on the product's active ingredient, concentration, tray fit, and the type of tooth stain.
What determines the results of at-home tooth whitening?
At-home whitening results depend on the product's active ingredient, concentration, tray fit, and the type of tooth stain.
How is peroxide gel applied during home whitening?
At-home whitening normally uses a peroxide gel placed in a tray or on a strip. Peroxide can break down some colored molecules within enamel and dentine, but it cannot change the color of fillings, crowns, veneers, or other restorations. The product name alone does not identify the formulation or the amount of active ingredient. Tooth sensitivity and gum irritation depend on the gel, contact time, tray fit, existing enamel wear, exposed roots, cavities, and how often it is used.
What should you check before using a whitening product?
Check the package for the active ingredient, instructions, expiry date, and warnings, and use only the stated amount and wear time. A dental examination should come first when teeth have untreated cavities, cracked enamel, gum inflammation, or marked sensitivity; a dentist can also check whether the discoloration is surface stain, internal tooth color, or a restoration.
When should you stop whitening and arrange dental care?
Stop using the product and arrange care if pain is severe, persists after use, or the gums become sore, pale, or blistered. Seek dental assessment before whitening if a single tooth darkens, because that can reflect trauma or loss of pulp vitality.
What should you ask about this product’s active ingredient?
What peroxide or other active ingredient does this product contain? Are my teeth, gums, fillings, and crowns suitable for whitening, and what result can this material realistically produce?
Frequently asked questions
Will it whiten a crown?
No. A crown keeps its existing shade, so a dentist must plan the color of natural teeth and restorations together.
What if my teeth are sensitive?
Pause whitening and have the cause assessed; exposed dentine, decay, cracks, and gum recession may need attention first.
