We hope to give you all the knowledge you need for fast teeth whitening by answering these questions.

How to whiten teeth instantly?

The short answer is that teeth can't be whitened instantly, but there are some methods, like laser teeth whitening, that bring fast results. Laser teeth whitening can be pricey, though, that's why we'll discuss all your options in this article.

A viable alternative is the Smile White teeth whitening kit. It does not only bring fast results, but also results that last up to 3 years. And unlike a costly laser teeth whitening, you can get started for just £16.45 per month. Click the button below to get started.

How does teeth whitening work?

The whitening agent in most whitening treatments is carbamide peroxide or hydrogen peroxide-based and it works by penetrating the enamel to reach the discoloured molecules inside your tooth. Oxygen molecules from the whitening agent react with the discoloured molecules in your teeth, breaking the bonds that hold them together.

When done correctly, it is a safe process for adults and teens.

While this means that you can't whiten teeth instantly, you can try out the following whitening methods and keep up with your dental hygiene.

How to whiten teeth instantly

Though it's not impossible, typically, you won’t get the results you desire instantly. Instead, you may have to repeat the whitening process multiple times, gradually whitening your teeth to get the desired results. Here are some ways you can whiten teeth fast.

Professional whitening 

Laser teeth whitening options

Potentially the quickest way to whiten teeth is by laser bleaching. This involves using lasers to speed up the bleaching effect of a concentrated whitening gel applied to the teeth. Although it’s the most expensive method, it’s also the closest you’ll get to “instant” teeth whitening.

Your dentist will first apply a rubber seal to protect your gums, then cover your teeth with a bleaching product – likely containing hydrogen peroxide for teeth whitening. Then, by shining a laser on your teeth, whitening happens much faster than with other treatments.

This intense whitening treatment should give clear results after just one visit. It does, however, have greater potential for sensitivity and temporary teeth dehydration following treatment.

Zoom teeth whitening

Zoom whitening technology is another of the fastest ways to whiten teeth. It works similarly to laser whitening but uses LED lights to accelerate a whitening agent.

LED teeth whitening systems are less intense, meaning less chance of sensitivity but also a longer treatment time (normally 3-4 sessions of 45-60 minutes).

Teeth whitening kits

First, you apply a bleaching gel to your teeth for a certain amount of time each day. Most kits come with a set of trays (which look like mouth guards) that fit your teeth and hold the gel in place.

The bleach seeps through your tooth enamel to whiten the dentin layer below. Dentin is naturally a darker yellow colour, which is why our teeth aren't perfectly white in the first place.

Our top pick for whitening kits in the UK is this one by Smile White.

A lot of DIY whitening kits that you can buy online are certainly affordable, but the results can be underwhelming and short-lived.

That's because, without professional supervision, the brands of remote treatments can't legally or safely provide customers with a whitening formula that is strong enough to see the results you want.

Smile White Pro changes the game by offering a kit developed and delivered by dentists, with results that last for up to 3 years.

Teeth whitening pens

Whitening pens are more like brushes; they consist of a small tube of gel that is applied directly to teeth via a built-in brush.

Pens usually contain hydrogen peroxide or carbamide peroxide, although some peroxide-free brands are available. Users like them because they're so convenient; you can carry them anywhere and use them whenever you have time.

Treatment takes 1-2 weeks, with about two applications per day lasting between 5 and 30 minutes, depending on the manufacturer.

Whitening strips 

There are many brands and types of strip solutions, but they all share some characteristics in common. White strips, in general, are thin, flexible, transparent, or translucent strips that are coated on one side with a teeth whitening gel.

Whitening Serums

The V34 Colour Corrector by Hismile is a gel that you brush your teeth with, ideally after or to supplement a whitening treatment. The V34 Colour Corrector serum is purple, which is key – opposite yellow on the colour wheel. It helps to balance yellow undertones and brighten teeth.

For a consistently brighter smile, you may use it as a whitening booster in addition to your normal toothpaste. This product is not intended to permanently whiten your teeth, as it is not designed for that purpose.

Home remedies for teeth whitening fast

Banana peels

Some believe if you rub a banana peel on your teeth using the inside of the peel, your teeth will become whiter. You do this daily before or after brushing your teeth. Supposedly, this causes your teeth to gradually get whiter over a few weeks. Science has yet to confirm whether this works.

Coconut oil 

One of the best quick teeth whitening home remedies is coconut oil pulling. You swish a spoonful of coconut oil around your mouth for 10-15 minutes. This is a traditional Indian technique for improving oral hygiene. You'll need to rinse and brush as usual afterwards, but you should notice that your teeth feel cleaner.

Homemade whitening paste 

You can create a homemade whitening paste using baking soda mixed with water, or a very small amount of hydrogen peroxide. Get a runny consistency and then rub onto teeth for 30 seconds after brushing normally. Limit this method to one or two times per week at most. Overuse can weaken tooth enamel.

How to remove stains from teeth instantly and whiten them

Although no treatment is permanent, you can help make your teeth whiter using some of these methods:
