How long does teeth whitening last?

Want to know how long does teeth whitening last? Teeth whitening is not permanent. After getting your teeth whitening treatment with our team at My Local Dentists, you can expect the results to last around  12 – 24 months on average. This is provided that you maintain good oral health and follow your dentist’s advice on keeping your white smile. 



However, as your teeth are exposed to food and drinks, the effects of teeth whitening will naturally wear off. Fortunately, several ways can help prolong the whitening effect. Let’s take a closer look at each to give you an idea of how to take care of your smile.


Tips to Prolong the Effects of Teeth Whitening

Now that you know that forever is not the answer to “how long does teeth whitening last”, how can you keep your smile from looking its best? The answer is proper maintenance. Here’s what you can do:


  • Avoid staining foods and drinks

Even after professional teeth whitening, consuming highly pigmented foods and drinks can quickly discolour your teeth. If possible, avoid coffee, red wine, acidic fruits, spices, and those with artificial colours. You could also consider rinsing your mouth with water immediately after eating to prevent these foods and drinks from leaving a stain on your teeth.


  • Do not smoke

Tobacco contains nicotine and tar, creating an unappealing yellow or brown tint on the teeth, particularly with frequent use. Smoking is also harmful to oral health and may cause gum disease, which can affect the long-term effects of teeth whitening


  • Reinforce your oral health

After teeth whitening, make sure to practice good oral hygiene routines continuously. This includes toothbrushing, flossing, and rinsing. These practices prevent the build-up of yellowish plaque that may affect the colour of your teeth. Good oral health is crucial to the success of many dental treatments, including teeth whitening.


  • Top up on your teeth whitening treatment

If your teeth look less white than they used to, you can always consider topping up your teeth whitening treatment. Ask your dentist for take-home whitening trays. These use the same ingredients as In Office Zoom teeth whitening and provide the same effect, with the difference being the same result can be conveniently accomplished in the comfort of your home.

Lastly, routine dental check-ups and professional teeth cleaning are also great ways to prolong the effect of teeth whitening. With your dentist’s help, they can eliminate plaque and tartar build-up, compromising your whitened teeth. And if there are any budding dental problems, immediate intervention can be provided to keep your oral health in excellent condition.
