Should i brush before using whitening strips
Brush before whitening strips only when directed, and avoid placing strips over wet toothpaste residue or irritated gums.
The short answer
Brush before whitening strips only when directed, and avoid placing strips over wet toothpaste residue or irritated gums. Follow the product instructions because brushing immediately before application can make sensitive gum edges more noticeable in some people.
How do whitening strips affect teeth and gum margins?
Whitening strips hold a peroxide-containing gel against the front surfaces of teeth. Brushing removes loose plaque, but the strip must contact clean, dry enamel and should not be folded onto the gums or used over decay, broken enamel, or untreated gum inflammation.
How should you prepare your teeth before using strips?
Read the label, brush gently at the usual time, and let the teeth and gum margins settle before applying the strip if the instructions allow it. Dry the teeth lightly, centre the strip on enamel, press it into place, and remove it for the stated duration without sleeping in it.
When should strip-related irritation be checked by a dentist?
Stop and arrange dental advice if the strip causes persistent burning, marked pain, gum whitening, or sensitivity that interferes with eating. A dentist should check pain from one tooth, visible cavities, cracks, or bleeding gums before further whitening.
What should you ask about safe strip use for your teeth?
Ask whether your toothpaste, gum condition, fillings, or exposed root surfaces affect strip use. Ask how to space brushing and whitening, and what to do if sensitivity appears after an application.
Frequently asked questions
Can I brush hard before strips?
No. Use gentle brushing because forceful brushing can irritate the gum margin before the gel is applied.
Should strips touch my gums?
They should be positioned according to the product design and not deliberately pressed onto the gum tissue.
