Does Mouthwash Actually Make Your Teeth Whiter?

Many people use mouthwash as part of their daily dental routine to keep their breath fresh and their mouths clean. But can mouthwash also help whiten your teeth? The answer is yes, but it depends on the type of mouthwash you use. Some mouthwashes are specially formulated to whiten teeth, while others are mainly for freshening breath and fighting cavities.

Does Mouthwash Remove Yellow Teeth?

Mouthwash can help remove some of the yellow stains on your teeth, especially if it contains whitening ingredients like hydrogen peroxide. Hydrogen peroxide is a bleaching agent that can help lighten the color of your teeth. However, mouthwash alone may not be enough to remove deep or stubborn stains. Regular use of a whitening mouthwash can help reduce surface stains and make your teeth appear whiter over time.

Listerine is a popular brand of mouthwash that offers a variety of products, including those aimed at whitening teeth. If you use a Listerine mouthwash that contains whitening agents, you might start to see results in as little as two weeks. However, the effectiveness can vary from person to person. For best results, use the mouthwash twice daily and follow the instructions on the label. Keep in mind that whitening mouthwashes work best when used alongside regular brushing and flossing.

What Is the Best Mouthwash for Whitening Teeth?

There are several mouthwashes on the market designed to whiten teeth. Here are a few popular options:

  1. Listerine Healthy White Vibrant Multi-Action Fluoride Mouth Rinse: This mouthwash contains hydrogen peroxide and helps remove stains and prevent cavities.
  2. Crest 3D White Luxe Glamorous White Multi-Care Whitening Mouthwash: This product not only whitens teeth but also strengthens enamel and freshens breath.
  3. ACT Whitening Mouthwash: Known for its enamel-strengthening properties, this mouthwash also contains whitening agents to help brighten your smile.

When choosing a mouthwash, look for products that specifically mention whitening on the label and contain ingredients like hydrogen peroxide. Always check with your dentist if you’re unsure which product is best for you.

How Can I Naturally Whiten My Teeth?

If you prefer natural methods to whiten your teeth, there are several options you can try at home:

  1. Baking Soda: Baking soda is a mild abrasive that can help scrub away surface stains. You can mix a small amount with water to form a paste and brush your teeth with it a few times a week.
  2. Hydrogen Peroxide: This common household item can be used as a mouthwash to help whiten teeth. Mix equal parts hydrogen peroxide and water, swish it around your mouth for a minute, then spit it out. Be careful not to swallow it, and use it sparingly to avoid irritating your gums.
  3. Apple Cider Vinegar: Known for its natural bleaching properties, apple cider vinegar can help remove stains. Dilute it with water and use it as a mouth rinse. Be sure to rinse your mouth with water afterward to prevent any damage to your enamel.
  4. Eating Crunchy Fruits and Vegetables: Foods like apples, carrots, and celery can help clean your teeth naturally as you chew. They act like a natural toothbrush, scrubbing away plaque and surface stains.
  5. Oil Pulling: This ancient practice involves swishing oil (like coconut oil) in your mouth for about 15-20 minutes. It is believed to help remove toxins from your mouth and whiten teeth over time.


While mouthwash can help whiten your teeth, it’s most effective when used in combination with good oral hygiene practices like brushing and flossing. For those looking for additional whitening, specialized mouthwashes containing ingredients like hydrogen peroxide can make a noticeable difference. Natural methods, such as using baking soda or hydrogen peroxide, can also be effective, but it’s important to use them correctly to avoid damaging your teeth and gums.

Always consult with your dentist before starting any new whitening regimen to ensure it’s safe and suitable for your dental health. With the right approach, you can achieve a brighter, whiter smile!
