Best Whitening Mouthwash (Dentist Tested & Reviewed) | My Dental Advocate

Most mouthwashes you find at the store seek to reduce the microbial load in your mouth.

However, other oral rinses treat various issues, including dry mouth, oral fungus, halitosis-stained teeth, and oral pain.

Today, you can find the most whitening mouthwash ingredients with varying concentrations. But what is the best whitening mouthwash?

As an experienced dentist with years of experience, I’ve tested and evaluated 300+ dental products. I strive to find the best products for achieving excellent oral hygiene, so let’s take a closer look at the Best Whitening Mouthwash from a dentist’s perspective.

Buying Guide

  1. Best Overall: Crest 3D White Brilliance
  2. Best Extended Whitening: ACT Whitening Anticavity Fluoride
  3. Best Budget: Amazon Basics Whitening Anticavity
  4. Best Anticavity: Listerine Healthy White Vibrant
  5. Best Flavor: Colgate Optic White Advanced Whitening

Evaluation Criteria

I (Dr. Hannan) tested each product for 7-14 days, detailing its pros and cons, and rated it from 1 to 5 in four key areas.

  • Effectiveness: Does the mouthwash treat the advertised need? How effective were the results?
  • Comfort: Are you able to swish for recommended time? Did it sting or burn? How did the mouth feel afterwards?
  • Taste: How was the overall taste? Was it tolerable? Did it alter your sense of taste?
  • Likeability: Were the directions clear and simple to understand? Do they desire unrealistic expectations?

Pros

Crest has excelled in the whitening space, and this product is no different. It was most effective at removing surface stains and most comfortable to swish because it’s peroxide-free.

Also, the clean mint flavor was satisfying. There was no taste alteration or dryness after spitting.

Cons

This product contains sodium lauryl sulfate (SLS), which can irritate people with sensitive gums. Also, sodium fluoride is not included in this product for cavity control.

Dentist Review

Pros

This product has a fantastic taste and is comfortable to swish between teeth. Hydrogen peroxide is a whitening agent which provides a soothing foaming sensation.

Due to the absence of alcohol, there was no dryness after rinsing. After four days of use, we observed a whiter smile.

This product benefits from the inclusion of fluoride, which strengthens the enamel and protects teeth from tooth decay.

Cons

Although this product has no alcohol, there was slight burning when swishing, which was eliminated upon spitting out the rinse.

Also, some people may find the foaming sensation uncomfortable, and subtle taste alteration was observed.

Highlights

  • A whiter smile in just 4 days
  • Sodium fluoride 0.02%
  • Alcohol-free and dye-free
  • Helps remove surface stains
  • Gentle mint flavor freshens breath

Dentist Review

Pros

This product has a refreshing taste and is comfortable to swish. It contains fluoride for cavity protection and peroxide to remove surface stains.

The peroxide foam was comfortable, and no taste alteration was observed. Whitening was observed; however, not as noticeable as ACT Whitening Mouthwash or Crest 3D White Brilliance.

Cons

There was slight burning during the first 20 seconds of swishing; however, it subsided. Also, this product contains alcohol, so mouth dryness was observed after rinsing.

Highlights

  • Removes surface stains from teeth
  • Sodium fluoride 0.02%
  • Whitening anticavity mouthwash
