Why do my teeth look more yellow after whitening?

Teeth can look more yellow after whitening because the whitening process removes some of the outer layer of enamel from the teeth, which exposes the underlying dentin. The dentin is naturally yellow in color, and so when the enamel is removed, the dentin is more visible and makes the teeth look more yellow. You can help minimize this by using a whitening toothpaste or using a whitening gel that helps to build up the enamel.

Why are my teeth stained after whitening?

Teeth staining after whitening is usually due to a few different things. One possible cause is that the whitening solution was not properly removed from the teeth, leaving behind residue that can cause staining. Another possible cause is that the whitening solution may have reacted with beverages or food that have staining properties, such as coffee, tea, wine, or berries. It’s also possible that the whitening process was not done correctly and that not enough time was left for the whitening agent to take effect. Lastly, it’s possible that the enamel of your teeth is naturally more porous than other people’s, causing it to absorb more of the whitening solution and resulting in staining.

Why don’t my teeth stay white after whitening?

Teeth whitening is a temporary solution and will only last for a certain period of time. The effects of teeth whitening typically last between four and six months, although this can vary depending on several factors such as your diet, lifestyle, and oral hygiene habits. To help maintain your teeth’s whiteness, avoid foods and drinks that can stain your teeth, such as coffee, tea, and red wine; brush and floss your teeth regularly; and use a whitening toothpaste.
