How Long Will the Results of a Teeth Whitening Smile Makeover Last?

Smile Makeover Kennewick, WA

People who want to improve the look of their smile may seek a smile makeover. This consists of one or more dental procedures to improve the look of the mouth and teeth. One of the most popular and simple ways to improve a smile is teeth whitening. There are a wide variety of options for teeth whitening, and the duration of results vary based on the type of whitening procedure and other factors.

Teeth whitening options

The quickest way to get bright and white teeth is in the dentist's office. When it comes to a smile makeover, there are a couple of options for teeth whitening. Their results, however, vary based on different factors. To help get the most effective outcome, the dentist may recommend a professional cleaning to remove plaque and surface stains before beginning the whitening procedure.

Teeth bleaching

One whitening option is traditional bleaching. To start, the dental professional takes a shade measurement of the teeth to help gauge how much brighter the teeth appear afterwards. Next, the teeth are polished, a cheek retractor is used to expose the teeth and keep the mouth open, and a protective gel is applied to the gumline and lips. 

The dentist then applies a whitening gel to the teeth. The bleach remains on the teeth from anywhere from 30 to 60 minutes and then is removed. Depending on what kit the dentist uses, the gel may stay on for shorter times but be applied repeatedly.

In-office bleaching is popular because it produces noticeable results that last a long time. The whitening stays noticeable for an average of 12 to 18 months.

Laser whitening

Laser whitening is becoming more common because it delivers faster and slightly better results than regular bleaching. The first steps are similar to the bleaching procedure. After the protective gel is placed and the whitening gel is applied, a laser is used to activate the gel. This helps to saturate deeper layers of enamel, which results in whiter teeth. After 15 to 20 minutes, the gel is removed, and the process is repeated two to three times until the desired shade is achieved.

Laser whitening results typically last 18 to 24 months. With optimal circumstances, results may even last up to three years.

Other factors that affect whitening results

Lifestyle and daily habits play big roles when it comes to how long whitening results last, as certain things increase stain development. Eating and drinking large quantities of staining items, such as coffee, tea, red wine, dark berries, and acidic foods, often shortens the results time. So does smoking.  

Age makes a difference as well, because as people get older, the tooth enamel thins out. Whitening procedures generally last longer in younger individuals. Practicing good oral hygiene is important for long-lasting whitening results. This means brushing and flossing regularly and getting a professional cleaning at least twice a year.


People interested in a smile makeover often choose teeth whitening. There are varying methods, and none last forever. However, professional methods get long-lasting results and do not have to be repeated as often as other options.
