How Long Does Teeth Bleaching Last?

One of the many questions patients have regarding the teeth bleaching procedure is how long the whitening lasts. Some even expect the results to last a lifetime. But unfortunately, teeth bleaching doesn’t last forever. Think of it as something you wash and then use, which means by time, it will get dirty again. But teeth bleaching will last for a certain time, during which you can enjoy your new smile and live with confidence.

The lifespan of your teeth’ bleaching will somewhat depend on the bleaching solution type your dentist will use. The common bleaching agents used in the procedures are either carbamide peroxide or hydrogen peroxide, but the concentration used can differ and the method opted for. Taking into account the several available teeth whitening options, on average, the results of teeth bleaching procedures can last between 6 months to 3 years.

Factors Affecting The Whitening Results

The time period for which your teeth bleaching lasts depends on the bleaching agent type, but your lifestyle will also affect the time for which the brightness lasts. This is the main reason that for one person, the teeth bleaching may last for two years, but for another, the results can fade away within five months. When talking about the effects of your lifestyle on teeth bleaching, what you eat and drink, and how clean you keep your teeth are the two most important factors to note.

How Teeth Bleaching Works

To understand how long teeth bleaching lasts, it’s also important to understand the working of this procedure. During the procedure, the bleaching or whitening agent is applied to your teeth and left to absorb. The agent penetrates from the enamel into the dentist layer of your teeth. Once it is inside, a chemical reaction starts at a molecular level and dissolves the tooth-staining molecules. Even after the whitening is removed from your teeth, it will continue to dissolve for the next 24 hours.

Your diet

A day after the bleaching gel is applied to your teeth, your body absorbs it, and it becomes ineffective from now on, which means that the gel has removed the previous stains and won’t entertain any new incomings. This is the reason people who intake too many highly pigmented foods and drinks lose the whitening results sooner than others. Items like tea, coffee, red wine, fruit juice, berries, beetroot, curry, and soy sauce contain colored molecules that your teeth absorb, and over time they turn discolored.

Your oral hygiene routine

Many of the stains that impact the shine and brightness of your teeth can be controlled with daily brushing and flossing, which is why it’s essential to clean your teeth daily to maximize the results. See your dentist regularly twice a year. During the routine cleaning, your dentist will remove any plaques formed on your teeth so it will be easier for you to clean them at home and prevent staining and discoloration. Be mindful of brushing your teeth right after eating or drinking highly pigmented-foods or beverages.


Summing up the above information, teeth bleaching procedures promise whiter teeth that can last as long as 3 years. But keep in mind that the results will be affected by your diet and your oral hygiene regime. To maintain your new smile for a long long time, it’s best to minimize the amount of foods and drinks that can stain your teeth and regularly brush and floss your teeth.
