A pearly white smile makes a good first impression, but yellow or dull teeth can greatly affect your self-image. They make your face appear older and might make you feel too embarrassed to smile or socialize.

You might be wondering how to keep teeth white when they start to look a little dull. Luckily, we’ve got tons of ways to whiten discolored teeth. Below, we’ll discuss different teeth whitening treatments and how to keep your teeth white after treatment. 

What this article covers:

Why Is it Necessary to Maintain Tooth Whitening?

It might be necessary to maintain tooth whitening for several reasons. But first, you need to figure out just how white your teeth really are.  

If you’re wondering how to tell if your teeth are white, eye-balling them is one sure-fire way. In other words, compare the whiteness of your teeth with the whiteness of your eyes. And if you don’t like what you see, consider making teeth whitening part of your lifestyle. 

What is teeth whitening? Teeth whitening is a procedure that brightens your teeth for aesthetic purposes for anywhere from a few months up to three years. 

How often should you whiten your teeth? You shouldn’t whiten your teeth too often. Dentist-approved whitening methods are generally safe, but using them too much can damage your enamel and cause gum irritation and sensitivity. Set up a regular routine for maintaining your pearly whites after whitening, then make lifestyle changes to keep them white for longer.

Professional Teeth Whitening vs. At-Home Teeth Whitening

Professional teeth whitening is a procedure that oral hygienists or dentists perform in-office. It uses two primary whitening agents - hydrogen peroxide and carbamide peroxide, to weaken intrinsic and extrinsic stains. The two most common methods of professional teeth whitening are laser teeth whitening and custom-fitted bleaching trays. 

Then there’s at-home teeth whitening, which involves DIY over the counter whitening products like gels, toothpaste, and strips. They contain lower concentrations of hydrogen peroxide and carbamide peroxide compared to professional teeth whitening, but they’re very effective for whitening in between teeth

What’s the best way to whiten teeth? At-home teeth whitening is the best way to whiten teeth by a landslide, and that’s because it’s:

  • Affordable: In-office teeth whitening costs about $800-$1000, while custom trays cost about $300-$600. Conversely, at-home teeth whitening kits cost about $25-$200.
  • Safe: At-home teeth whitening kits are generally safe and highly effective. They can lift intrinsic and extrinsic stains from your teeth, making them visibly whiter after several weeks. 
  • Convenient: You can do DIY whitening at home without visiting a dentist or oral hygienist.

If you're considering whitening at home, here are some magic products to keep your teeth white and healthy.

How to Maintain White Teeth After Treatment

After completing any of these whitening treatments, we recommend following these tips to maintain a healthy smile.

Avoid Acidic Foods

One of the biggest no-nos for maintaining your pearly white smile is acidic food. They damage and discolor your tooth enamel, and they also put your oral health at risk. Avoid foods like citrus fruits, pickles, and vinegar to prevent any further staining.

Avoid Sour Fruit Juice

Do you love sour fruit juices? Bummer! They’re highly acidic, not to mention that they weaken the enamel and cause staining. Avoid sour juices like tomato, cranberry, and grapefruit juices to keep your chompers in peak condition. 

Use Straws

Whenever you drink coffee, tea, or any other type of staining liquid - suck, don’t sip. Using straws prevents the beverage from making direct contact with your teeth and causing discoloration. We recommend using eco-friendly drinking straws (preferably paper ones) that help the environment. 

Don’t Forget to Floss

Our research indicates that flossing regularly is an excellent way to keep your teeth white. Flossing removes particles and debris stuck between your teeth, which can cause discoloration. 

Brush Your Teeth With Whitening Toothpaste

Good oral hygiene helps prevent staining and keeps your teeth white. Brush your teeth twice a day, but not with just any old toothpaste. Opt for a whitening toothpaste that contains amino acids, vitamins, herbs, and hydroxyapatite to effectively remove staining. Pair it with a refreshing aloe and mint whitening mouthwash to keep your breath feeling clean and fresh all day long. 

This teeth powder magically converts regular toothpaste into whitening toothpaste. It’s enamel-safe, has a delicious lavender and mint flavor, and you can use it up to four times a week.
