Not all teeth whitening procedures work the same for everyone. So even when a specific brand of whitening strips or a particular teeth whitening toothpaste works miracles for one of your friends, it may not work for you.
If you’re using a non-professional teeth whitening toothpaste or a brand that does not contain peroxide, you are going to be disappointed. The active ingredient in most commercial whitening products is hydrogen peroxide. It’s the best whitener when it comes to boosting whiteness and killing bacteria-causing the discoloration as well.
The other teeth whiteners available only work on surface stains. If you’re looking to get rid of the yellowing and graying, you need to get the good stuff. But it isn’t enough to choose a teeth whitening product, you also need to find the right one that is perfectly suited for you.
7 Reasons Why Your Teeth Whitening Didn’t Work.
It is very important to stick to the recommended application guide. Follow this carefully and don’t be tempted to be lazy.
If you travel a lot and can’t always use the product as prescribed, then keep up with it whenever you can.
You may notice whitening but it is often a slow process, and there is no way to speed it up.
Your teeth are too stained and or old
This is a very common reason for teeth whitening not to work. The tooth shade can only go so far. Don’t expect your back teeth to whiten as much as your front teeth, and don’t expect your teeth to go from blue to white. The shade change is possible but not the color change.
Old and worn out teeth may still not be white even after the whitening process has been completed. This is because, they may look almost white, but not quite.
Because of the years of abuse and neglect, they are not able to return to a completely white shade. There are, however, teeth whitening products that are designed specifically for old teeth.
