Teeth whitening is easily one of the most popular cosmetic dental treatments, and for good reason! Teeth whitening helps address the issue of discoloured, stained or yellow teeth to achieve a better, brighter smile. Ranging from whitening toothpaste to professional in-chair whitening with a dentist, there are now countless ways to whiten your teeth. 

But, how often do you need to whiten your teeth? The length of time that teeth whitening lasts will depend on several factors, including how you whiten them and also your oral hygiene habits. Let’s explore these further!

How long does teeth whitening last?

In short, this depends on various factors. The effects of teeth whitening generally can last from 6 months to 3 years, varying from person to person. For those who don’t maintain their oral hygiene or make certain lifestyle choices, it can be harder to retain white teeth. For example, people who smoke, eat staining foods like berries or curries, or drink a lot of coffee, tea or red wine will find their teeth will discolour faster.

In-chair teeth whitening will also last for longer than at-home teeth whitening, as it is a more powerful treatment. With either option, it’s also best to be aware of the biggest teeth whitening myths so you can be informed about the process involved.

How long does teeth whitening take?

While your teeth may lose their whiteness over time, there are a few ways you can slow down the process. For starters, maintaining a good dental hygiene routine starting with brushing your teeth twice a day provides several oral health benefits, in addition to removing staining particles. Reducing staining foods and caffeine can also help retain white teeth longer, as well as swishing water around the mouth after eating and drinking.

Dentists who perform teeth whitening procedures use stronger whitening formulas that last much longer than home remedies. A single in-chair whitening session can take as little as an hour and can help you get significant results. Similarly, you can get home whitening kits custom-made for your mouth from your dentist. You will need to add the whitening agent to the tray and wear it for short periods of time, ranging from 15 minutes to overnight depending on the strength of the formula.

However, this process is a bit slower and may take 1-2 weeks for the effects to build up over time. This is because at-home whitening uses agents with lower concentration than in the chair with your dentist.

How effective is teeth whitening?

The results of the whitening process differ from person to person. It depends on the current state of your teeth and type of whitening treatment selected. While most people will see a noticeable difference after the procedure, the change isn’t the same for everyone. It’s also important to be aware that the whitening process will not improve the colour of any fillings or restorations. Once you achieve your desired shade of whiteness, you may prefer to replace fillings, composite bonding, porcelain crowns or veneers to better match your real teeth.

What’s the best way to whiten your teeth?

As mentioned earlier, you may opt for at-home teeth whitening or in-chair teeth whitening. However, the results, pros and cons of the two methods will differ. Let’s compare at-home whitening vs in-chair whitening:

At-home teeth whitening

Whitening your teeth at home offers the benefits of being more affordable and causes less sensitivity as the whitening agents are not as strong. It’s a convenient option that can easily fit into your own schedule, and you have more control over the level of whiteness as you gradually do it over time. You can also maintain the colour by using your whitening kit at regular intervals over time after the initial period is complete.

The downside of at-home whitening is that the process is a bit slower than in-chair treatments. 

Whitening trays bought from the supermarket can cause irritation and redness in the gums and mouth as they will not be custom fitted to your teeth, which is why we highly recommend purchasing a custom kit from your dentist if proceeding with the at-home whitening option. This option also means you need to remember to use the kit repetitively to achieve results.

In-chair teeth whitening

The main benefits of in-chair procedures is that they produce faster results, and can help you achieve the whitest possible smile. It may not be the preferable option for everyone though, as  it’s more expensive. In addition, the stronger whitening agent can cause sensitivity and discomfort for some, which is why it’s important to have a consultation with your dentist first to determine if this treatment is right for your unique needs.

Which should I choose?

As you can see, both in-chair and home whitening treatments have their pros and cons.

The results can last anywhere from 6 months to 3 years, depending on the kind of care you take and the treatment you decide on. If you’re unsure about which option is best for you, book a complimentary cosmetic consultation with the experienced dental team at Oasis Dental to help you determine the most safe and effective treatment for your needs.
