How Long Does Teeth Whitening Last?

how long does teeth whitening last

If you’re considering upgrading your grin, you might be wondering how long does teeth whitening last? After all, we all want a sparkling white smile, and when we have it, we’d like it to last as long as possible. Unfortunately, though, no matter what whitening product or process you use, your teeth won’t remain that wonderful shade of white indefinitely.

The length of time your newly whitened smile will last will depend on the products you used to attain pearly white perfection. And how you care for your teeth following your treatment. Read on to find out how to safely brighten your beam and how long you can expect your teeth whitening to last.

Why Your Teeth Are Discoloured

Annoyingly, some people just have naturally thicker enamel and whiter teeth than others. But we’re all at risk of staining our teeth, whether we have a naturally more sparkly smile or not.

There are lots of possible reasons why your teeth are discoloured or have become yellowy over time, such as:

  • Consuming particular food and drinks
  • Getting older
  • Smoking — vaping or smoking cigarettes
  • Medications taken when adult teeth were developing
  • Tooth damage, decay, or infection

Types of Staining

Before starting any whitening treatment, it’s worth assessing the type of teeth staining you have. Whether your stains are intrinsic or extrinsic will make a massive difference to the outcome of your treatment.

Intrinsic Staining

If your stains are intrinsic (internal), the discolouration of your teeth is probably down to medication, trauma, infection or just getting older. Intrinsic stains are much harder to shift than extrinsic staining.

Extrinsic Staining

If your staining is extrinsic (external), it’s most likely been caused by smoking or consuming teeth-staining food and drink. The good news is that teeth whiteners are effective at removing extrinsic staining.

How Long Does Teeth Whitening Last By Treatment?

Whichever teeth whitening option you go for, looking after your teeth and keeping them clean will help your luminous smile last longer. Here are the most popular whitening treatments available today:

Whitening Toothpaste

Whitening toothpaste contains mild abrasives and the bleaching agent hydrogen peroxide or carbamide peroxide to remove surface stains from teeth. If your whitening toothpaste only contains abrasives, take care not to use the toothpaste for too long as you’ll run the risk of damaging your enamel, causing your teeth to become overly sensitive.

How long does teeth whitening last after using a whitening toothpaste? Depending on the toothpaste you use, you should notice a difference after two to six weeks of twice-daily brushing. And you can expect your teeth whitening to last for about three or four months.

Whitening Mouthwash

A whitening mouthwash will typically contain hydrogen peroxide and is designed to be used every day. As it can take quite a while to see any results from using a whitening mouthwash (around three months), it may be a good idea to use it following a faster and more effective whitening treatment to prolong your pearly look.

Whitening Strips

Depending on the brand you opt for, whitening strips can be a good over-the-counter option. And it’s possible your whiter teeth could last for as long as six months. But results with whitening strips can be inconsistent. And you could be waiting quite a while before any noticeable colour change happens.

As peroxide is used in whitening strips to lighten teeth, don’t be tempted to stick a strip on too often, or you could end up with painful gums or damaging your teeth. If you have sensitive teeth, be careful with whitening strips.

Whitening Kits

A dentist-approved teeth whitening kit is a highly effective way to get noticeable results quickly and that last. You’ll see your teeth begin to get whiter in just a week — and with some whitening kits even sooner than that. You’ll have reached your ideal shade in a swift two to four weeks.

Teeth whitening kits work by filling a tailor-made mouth tray with a whitening gel. Depending on the provider, you’ll need to wear for a short amount of time each day or sleep in your gel-filled tray overnight.

In-Clinic Whitening

Having a dentist whiten your teeth in their surgery can also be a highly effective way to achieve a sparkling smile. In-clinic whitening will involve a dentist applying a bleaching agent to your teeth and often using an infrared laser to speed up the whitening process.

Although in-clinic teeth whitening can be fast and effective, it’s also considerably more expensive than other methods.

Can Teeth Whitening Cause Problems?

Your teeth or gums may feel a little sensitive following a whitening treatment. But this sensitivity shouldn’t last long.

Remember, though, whichever method you choose to whiten your teeth, it’s essential to use any whitening product as instructed. Don’t be tempted to overuse any product, or you could cause yourself some undesirable dental issues and damage your teeth.
