Everyone desires the bright, megawatt smile sported by Hollywood celebrities. Still, not everyone has teeth like that or can afford to get veneers (that’s the secret behind those picture-perfect teeth). So, they ask, “Is teeth whitening a better option? How long does teeth whitening last?

While veneers are expensive and unnecessary (you have to grind down your existing teeth to attach them), teeth whitening is a far better and more economical alternative if it lasts long.

It all depends on whether you get your teeth whitened professionally or plan to use a DIY kit or home remedy. Home remedies tend to last less long and can even damage your teeth if performed improperly. 

The lifespan of a professional teeth whitening depends on the type of bleaching or whitening agent used by your cosmetic dentist. Let’s explore how long does teeth whitening last in greater detail below. 

Why You May Need Teeth Whitening?

Once our permanent teeth finally come in, they are usually white. Yet, they may not seem as pearly bright as the ones in the toothpaste commercials. That’s because the teeth in those pictures are edited to look extra bright. 

Your teeth have a natural base color and brightness that compliments you perfectly and looks natural. Sometimes whitening your teeth to a bright white can make you look artificial. That’s why it’s best to get your teeth professionally whitened by a cosmetic dentist who will provide you with a brighter smile while making sure your smile looks natural. 

One of the things that are unavoidable as you age is your teeth turning yellow or dull. This discoloration usually happens due to one or more of the following factors:

Poor Dental Hygiene

Failing to brush regularly, i.e., twice daily or floss at least once a day, can lead to plaque formation, discoloration, and even tooth decay. 

Age-Based Deterioration

As you age, your enamel gradually wears away, making your teeth look brown or yellow. 

Dental Conditions

Gum disease or other conditions that damage the tooth enamel cause stains and spots on your biters. 

Strong Medications and Mouthwashes

Some medicines and mouthwashes can also damage and discolor teeth. 

Missing Dental Check-Ups and Cleaning

There’s a reason why you’re supposed to show up for regular dental checkups and cleaning every 6 months. Your dentist examines your mouth thoroughly to ensure that no problems have developed, i.e., cavities, tooth decay, periodontal disease, etc. They will also give you a dental cleaning to remove any plaque build-up and keep your teeth bright, clean, and shiny. 


You can’t fight genes. Some people just inherit teeth with a thicker or whiter enamel and end up with a bright smile. Similarly, some are born with naturally yellow teeth. You should take good care of them and not weaken them by bleaching them too frequently. 

Severe Dental Trauma

In some rare cases, dental trauma can break or even discolor teeth.

Some stains, such as those caused by smoking and drinking, can set in deep and become very difficult to remove. The ones caused by dental conditions require the underlying disease to be treated first. 

Meanwhile, common stains can be removed using professional or over-the-counter teeth whitening products. Yet the question remains, “How long does teeth whitening last?”

What are the Different Ways of Teeth Whitening?

What are the Different Ways of Teeth Whitening

The most popular over-the-counter teeth whitening products include:

Using these products requires patience, as it may be several weeks before you see visible results. These products are also best for regular stains but will be ineffective against the ones caused by disease or trauma. 

Teeth whitening gels and strips typically use peroxide to whiten your teeth; the results usually last for around 4 months. Be careful of using them too frequently or using products with a high peroxide content, as it wears away the enamel and causes tooth sensitivity. 

The same goes for baking soda. Frequent use can weaken your teeth’s enamel and cause extra sensitivity. 

In the case of a professional teeth whitening performed by a dentist, you get superior results as a dentist uses more effective products than you can find over the counter. They also ensure that the bleaching agents don’t harm the soft tissue in your mouth, such as your gums, or damage your teeth.
