Do you brush your teeth before using crest white strips
Brush gently before whitening strips if needed, but follow the product directions and avoid applying strips to irritated gums.
The short answer
Brush gently before whitening strips if needed, but follow the product directions and avoid applying strips to irritated gums. Do not brush aggressively immediately before whitening because that can irritate the gum margin.
What is the direct answer?
What does this question mean?
Whitening strips hold a peroxide-containing gel against the front surfaces of teeth. Brushing removes loose plaque, while whitening changes the color of some tooth structure and does not remove tartar or treat decay.
What can you do next?
Clean your teeth gently, rinse, and let the mouth settle before placing the strips if the package permits it. Keep the gel off the gums, use only the stated wear time, and stop if sharp sensitivity or burning develops.
When should you seek dental care?
Arrange an examination if whitening causes persistent pain, gum injury, or uneven color, or if a tooth has a cavity, crack, or large filling. A dentist can check whether discoloration is inside the tooth or on its surface before whitening.
What should you ask the dentist?
Ask whether the discoloration is suitable for peroxide whitening and whether existing fillings, crowns, or veneers will match. Also ask how to manage sensitivity and whether gum recession is exposing root surfaces.
Frequently asked questions
Can I use strips after brushing?
Yes, if brushing was gentle and the product directions allow it; avoid whitening over irritated gums.
Will strips whiten fillings?
No. Whitening changes natural tooth color, so existing fillings and veneers may not change shade.
