Why do my teeth look more yellow after whitening strips?

Your teeth might look yellow after whitening strips because the strips thin your enamel, revealing the naturally yellow dentin underneath, or because they can't remove deep, intrinsic stains, leaving a yellow tint, especially if you have naturally darker dentin or have used certain medications. The initial whitening removes surface stains, making the tooth more porous and susceptible to new stains, while the underlying yellow can become more apparent as the enamel thins, says dentist.

Why don't my teeth stay white after whitening?

Your teeth don't stay white after whitening because enamel becomes temporarily porous, allowing stains to re-set, and because diet (coffee, tea, red wine), tobacco, poor hygiene, and even the natural yellowness from dentin will cause re-staining over time, requiring regular touch-ups and diligent care to maintain results.
 

Will my teeth get whiter if I leave whitening strips on longer?

Professional dental work, like fillings or sealants, is needed for significant decay, but lifestyle changes and specific products can prevent further loss and harden what's left.
