Before you begin a tooth whitening treatment, you'll want to know what to expect with teeth whitening, before and after your treatment. Some whitening procedures yield dramatic results after a single treatment, while others will whiten gradually over a few weeks.

There are also some treatments where you aren't likely to see very noticeable results at all — these can be brands that make false claims, whitening toothpaste and mouthwashes, or natural whitening methods.

In this article, we'll show you various teeth whitening before and after results and we'll also discuss:

  • Different ingredients and their effects
  • Whitening results by product
  • What to expect after whitening

We hope this information helps you choose the best whitening procedure for you and the results you want to achieve with your tooth whitening treatment.

Before/after results with our #1 recommended teeth whitening kit

Professional whitening before and after

Professional teeth whitening is going to deliver by far the fastest and most noticeable results. There are various treatments you can get done in-office, including laser teeth whitening, Zoom teeth whitening, and bleaching with custom trays.

There are also some professional options that include treatment both in office and at home. Boutique whitening is done with custom trays that you take home with your whitening formula.

If you are considering getting your teeth professionally whitened, the best place to see before and after whitening results is at the dental office. They should be able to show you past client dental teeth whitening before and after photos before you make a decision on your whitening treatment.

At-home teeth whitening before and after

At-home teeth whitening kits are more affordable than professional whitening, and they also take a bit longer to see results. But with some whitening kits, like the ones we will mention below, the results can be quite comparable to professional whitening once you've finished treatment.

Smile White before and after

The Smile White Teeth Whitening Kit is our top pick!

Smile White has the best professional teeth-whitening system that comes in a handy at-home kit. Unlike the DIY whitening kits you can buy online, the Smile White formula is dentist-strength — up to 100x stronger than those other kits. Take a look at some of their before and after results:

Snow before and after

Snow is a popular teeth whitening kit that whitens with a hydrogen peroxide gel that you brush on your teeth and a blue LED light. According to Snow, 90% of customers see results after the first use. Have a look at a couple of examples of Snow whitening before and after results:

Hismile before and after

Hismile is another popular at-home teeth whitening brand, but instead of using peroxide to whiten teeth, it uses pthalimidoperoxycaproic acid (PAP). PAP is becoming quite popular because it whitens with the same results as hydrogen peroxide, but without any of the sensitivity.

Although Hismile no longer sell their whitening kit, they do provide a wide range of whitening products with great results! The gel that Hismile sell is the same gel that gave these results, you would just need an alternative tray to use the gel within. You can buy the products individually or alternatively you can get the HiSmile Whitening Bundle, this includes the gel and other products such as the HiSmile powder and toothpaste.

Natural whitening before and after

There are myriad natural whitening methods out there, but unfortunately, most of them just aren't that effective, and worse, some of them could do more harm than good. Some methods include:

  • Fruit: Banana peels, strawberries, and lemons are said to have whitening effects
  • Baking soda: Baking soda might whiten your teeth, but its abrasiveness will likely harm enamel
  • Charcoal: Some people claim to see results from activated charcoal, but many dentists warn against its use

In the video below, dental hygienist Whitney goes over some of the most common at-home and natural whitening options. She talks about some of the best and worst and shows her before and after whitening results. (Keep in mind that as a dental hygienist she also may be a bit biased towards in-office procedures).

Teeth whitening before and after photos

When researching potential whitening procedures, it's normal to want to look at before and after photos of people who have undergone whitening treatment. But, as you do, make sure to keep an eye out for photos that have been doctored. The main giveaway is if the lighting in the after photo is overexposed.

The best way to tell is if the lips and skin around the teeth in the after photo is also much lighter than they are in the original photo. This is very common in customer reviews for teeth whitening brands. Here's an example where you can see that the gums on the left are also darker than they are on the right:

You should also check to make sure the photo doesn't look too flawless, because it may very well be photoshopped — here's an example:

Teeth whitening before and after photos can help you decide if a teeth whitening treatment really works. You'll see the most drastic results with in-office, professional whitening procedures, but there are also at-home whitening options that provide noticeable results and are much more affordable.

Don't fall for claims that any whitening treatment is permanent — you'll still need to maintain good oral hygiene.

You should be able to find unbiased reviews online which include teeth whitening before and after photographs as well as dentist teeth whitening before and after photographs.

As you're looking through before and after photos, make sure to watch out for ones that have been too obviously edited, or where the gums and lips in the after photo are also much lighter than they were in the before photo — teeth whitening is meant to whiten teeth, not the areas around your teeth too!
