Teeth whitening is designed to make your teeth brighter, not yellower. While teeth whitening products may make your teeth appear whiter, they can also cause teeth to become more sensitive and yellow in the long run. To avoid yellowing teeth, it is important to use teeth whitening products sparingly and to follow the instructions provided on the product packaging. Additionally, it is important to maintain good oral hygiene practices, such as brushing and flossing regularly, to reduce the risk of yellowing teeth.

Why are my teeth yellow again after whitening?

Teeth can become yellow again after whitening for a variety of reasons, including poor oral hygiene practices, consuming certain foods and drinks, and lifestyle habits. Regular brushing and flossing, avoiding foods and drinks that can stain teeth, and quitting smoking can help prevent teeth from becoming yellow again. Additionally, using a whitening toothpaste or mouthwash can help maintain the whitening results.

How long does it take to whiten yellowed teeth?

In general, the process of whitening yellowed teeth usually takes anywhere from a few days to a few weeks depending on the severity of the discoloration. If you choose to use an over-the-counter whitening product, you should expect a gradual lightening of your teeth over the course of several weeks. If you opt for a professional whitening treatment, your dentist can provide more immediate results. Professional treatments often use a combination of bleaching agents, light, and heat to dramatically lighten the color of your teeth in just one session.
