What not to do after teeth whitening

Teeth whitening is one of the most affordable cosmetic dental procedures in the world. It’s also extremely popular among people of all ages because it can have a significant impact on the appearance of your smile and level of confidence. 

One common concern, though, among people who have successfully whitened their teeth is that the effects might not be long lasting. 

So what should you do, or not do, to maintain your pearly whites for the longest time possible?

After teeth whitening, it is easy to overlook the fact that you are in a post-treatment stage because the procedure is rather simple and straightforward. Some people believe that professional teeth whitening can make your teeth even more discolored. This assumption is based on the idea that people who have used whitening before often require subsequent treatment to maintain the result. 

Fact is, your teeth will be more vulnerable to discoloration from foods and beverages with dark color pigments, in the period immediately following your teeth whitening procedure. This is because the dentist uses a high-strength whitening gel while opening the “pores” (or tubules) in your teeth during the teeth-whitening operation. This gel bleaches the tenacious stains on your teeth while penetrating the tooth enamel.

So after the whitening procedure, you must be careful about what you consume, especially for the first couple of days when your teeth are still newly treated for whitening. At this point, these pores will be more susceptible to discoloration.

How long do teeth whitening results last?

There are different types of patients who often opt for tooth bleaching including:

  • Individuals with yellowed or stained teeth
  • Individuals whose outer layer is eroded or stained by medications like tetracycline
  • Those whose teeth were subjected to excess fluoride resulting in fluorosis

Before you start your teeth whitening process, it is important that you first schedule a teeth cleaning procedure. This is because the build-up of plaque can limit the success of the whitening process. Plaque is dangerous because it not only contributes to gum disease and tooth decay, but also promotes the accumulation of bacteria and stains that cause your teeth to discolour. Failure to sufficiently remove the plaque will lead to uneven teeth whitening.

While most people are suitable candidates for whitening their natural teeth, the results and duration the effects of whitening last vary from person to person depending on the bleaching method used and carious lifestyle factors. Generally, you can expect the results to last for at least 6 months, and up to 3 years before noticeable discoloration.

Some of the things that may stain your teeth and shorten your whitening results include consuming dark liquids and staining foods, as well as chewing or smoking tobacco products.
