How to Whiten Teeth Perfectly in App for Free

Are your yellow teeth bothering you? Do you want to whiten teeth in photos? Do your pale-colored teeth look ugly to you?

Worry no more. I’m here for you. I’m going to show you how can you whiten your teeth in your photo fabulously. We’re going to use an app for it. Plus, whitening teeth is totally free.

Before we show you, let me show you what info you can get from this tutorial.

What causes yellow teeth in photos?

Many times teeth appear yellower in photos than they actually are.

This is because of the light source.

When there’s enough light, teeth don’t appear that yellow. But when the light isn’t enough or the surrounding light has a yellow tone, your teeth are likely to look yellower than they actually are.

How to avoid yellow teeth in photos?

It’s easy to guess the answers as we already know what causes yellower teeth in photos.

  • Simply avoid taking photos when the surrounding light source is yellow.
  • Use camera flash during the night. It reduces the yellow tint in photos.

Is there an app to whiten teeth in photos?

Yes, there are many.

To whiten teeth in pics, we’re going to use a free app. We’re going to use PicsArt.

It’s a free app. You can download it from the Apple App Store or Google Play

Step 2 – Whiten the teeth in a photo on an app for free

Make the following adjustments.

This will change the entire photo. But we’ll fix it later.

Our goal right now is to make sure that the teeth look white.

  • Saturation: -82
  • Brightness: +4
  • Highlight: +45
  • Clarity: +14
  • Contrast: +15

Now, our teeth look bright and white.

Step 3 – Undoing the brightening of the other parts

Tap on the Eraser icon.

Tap on Invert. This will invert all the changes.

Zoom in to the teeth to whiten them.

Tap on Restore. 

Change the brush dimensions to this.

  • Size: 58
  • Opacity: 100
  • Hardness: 70

Now, start brushing only the teeth to whiten them.

Here’s a short video for you.

Keep on doing it until you brushed all your teeth white.

You might’ve brushed some parts of the gum gray.

We’re now going to fix it.

To fix this, tap on the Eraser icon.

And now brush on the parts that you don’t want to be grayed out.

That’s all! You have whitened the teeth successfully in your photo.
