40 Crest whitening strips
Whitening strips use peroxide on the tooth surface; follow the product directions and stop if sensitivity or gum irritation develops.
What is the direct answer?
Whitening strips use peroxide on the tooth surface; follow the product directions and stop if sensitivity or gum irritation develops.
What does this question mean?
A whitening strip is a flexible carrier coated with a peroxide-containing gel. The peroxide can break down some colour molecules in natural enamel, but fillings, crowns, veneers, and other restorations do not whiten in the same way.
What can you do next?
Read the label for wear time, frequency, storage, and warnings, and apply the strip only to clean, intact teeth as directed. Do not extend the course or layer products; manage sensitivity by pausing and discussing alternatives with a dental professional.
When should you seek dental care?
Have a dental examination before whitening if you have cavities, cracks, gum recession, exposed roots, untreated gum disease, or unexplained sensitivity. Stop and seek advice for painful sensitivity, white or burned-looking gums, swelling, or a reaction that persists.
What should you ask the dentist?
Ask whether the shade change is suitable for your teeth and whether existing restorations will match afterward. Ask which concentration, application method, and schedule fit your enamel, gums, and sensitivity history.
Frequently asked questions
Can I use whitening strips longer to make teeth whiter?
No; extending wear time can increase exposure and irritation without addressing the cause of discoloration, so follow the product directions.
Why are my gums white after whitening strips?
Gel that contacts the gum can irritate the tissue temporarily; remove the product and seek advice if the change is painful or does not settle.
