How does teeth whitening work?

The whitening agent is usually carbamide peroxide or hydrogen peroxide-based and penetrates the enamel to reach the discolored molecules inside your tooth. Oxygen molecules from the whitening agent react with the discolored molecules in your teeth, breaking the bonds that hold them together. When done correctly, it is a safe process for adults and teens.

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

How to whiten teeth at home in one day

Though it is 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

Laser bleaching uses lasers to speed up the bleaching effect of a concentrated 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 will 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, but it also has greater potential for sensitivity and temporary teeth dehydration following treatment.

Zoom teeth whitening

Zoom whitening technology works in a similar way to laser whitening but instead 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).

Fast teeth whitening products

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 color, which is why our teeth aren't perfectly white in the first place.

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 numerous 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 tooth whitening gel.

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 if 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 afterward, but you should notice that your teeth feel cleaner.

Homemade whitening paste 

A homemade whitening paste can be concocted 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. This method should be limited to 1-2 times per week at most. Overuse can weaken tooth enamel.

Tips on how to keep your teeth white and prevent stains
