Safe teeth whitening products
Whitening products act mainly through peroxide, and the suitable choice depends on enamel, gums, fillings, sensitivity, and the cause of staining.
How do you choose a suitable teeth whitening product?
Whitening products act mainly through peroxide, and the suitable choice depends on enamel, gums, fillings, sensitivity, and the cause of staining.
What affects whitening results and discomfort?
The result and discomfort depend on concentration, contact time, tooth structure, existing sensitivity, gum exposure, and whether the discolouration is on the surface or inside the tooth. Untreated decay, cracks, gum disease, and some intrinsic stains need assessment first.
How can you use whitening products more safely?
Check the ingredient list, follow the product instructions, keep gel off the gums, and stop if you develop significant pain, burns, or gum irritation. A dental examination can identify restorations or disease before whitening.
When should you see a dentist before whitening?
Seek dental care before whitening if you have pain, cavities, gum bleeding, exposed roots, cracks, or one dark tooth. Arrange review if sensitivity or gum irritation persists after stopping the product.
Which whitening product and treatment plan suit your teeth?
Ask which peroxide formulation suits your teeth, whether fillings or crowns will match afterward, how to manage sensitivity, and whether the stain needs another treatment.
Frequently asked questions
Are whitening strips the same as dental whitening?
They may use similar bleaching chemistry, but the formulation, fit, contact time, and supervision differ.
Why do teeth feel sensitive after whitening?
Peroxide can temporarily irritate the tooth nerve and exposed dentin, especially when teeth already have sensitivity.
