Who Can Perform Whitening Process?

A professional dentist should ideally carry out the whitening process. Some beauty salons also offer teeth whitening, but this is illegal if there’s no dental professional present. And note that they put your oral health at risk as they are not medically trained to provide oral healthcare. 

You can also buy DIY home teeth whitening kits, but even they are extremely dangerous and can erode your tooth enamel while increasing tooth sensitivity.

How Long Does It Last?

Whitening of teeth done by a professional can last between 2 to 3 years, whereas other whitening methods only last a few months. For a brighter smile, professional teeth whitening is an investment.

Below is a brief overview outlining how long whitening performed by a dentist lasts. This review covers teeth whitening in-office, the dentist’s take-home trays, and over-the-counter whitening agents available on the market.

How Long Does Teeth Whitening Last

It is the most effective if done by a dentist in-office because the solution they have access to is much stronger than any in-store product. Dentists also have tools and instruments that help to enhance these solutions making the results better and longer-lasting. 

Typically, patients experience results that last up to three years, depending on the severity of the teeth stains. However, it can take multiple rounds of whitening to get to the desired shade if the stains are incredibly strong.

Therefore, the results of the initial treatment are necessarily essential. In this case, the results can last around a year after multiple treatments.

The patient gets more control regarding the teeth whitening treatment with take-home tooth whitening trays. However, patients should expect the process to take longer because the treatment is done at home. Whitening trays are generally used multiple times for a couple of weeks. 

The result varies for everyone regarding how long the results from take-home teeth whitening trays last. Usually, the results will last for six to eight months, but in some scenarios, they may last for up to a year.

Dentists recommend staying disciplined with the teeth whitening trays to achieve longer-lasting results. Discipline means applying the appropriate amount of solution and wearing the trays for the allotted time. It is also highly advisable to avoid smoking and drinking heavily dyed beverages immediately after the treatment.

Over-the-counter whitening agents include whitening gels, strips, and toothpaste. Though they are readily available on the market, these products are less effective than the other methods mentioned above. 

Their whitening process and the final results take longer than you can realize. Without following the proper guidelines, patients risk hurting their gums and potentially damaging the enamel of their teeth.
