Dentist Tested and Reviewed

Updated: January 10, 2024
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 250+ dental products. I strive to find the best products for achieving excellent oral hygiene, so let’s take a closer look at the 5 Best Whitening Mouthwash from a dentist’s perspective.
- Best Overall: Crest 3D White Brilliance Mouthwash
- Best Extended Whitening: ACT Whitening Anticavity Fluoride Mouthwash
- Best Budget: Amazon Basics Whitening Anticavity Mouthwash
- Best Anticavity: Listerine Healthy White Vibrant Mouthwash
- Best Flavor: Colgate Optic White Advanced Whitening Mouthwash
I test each product for 7-14 days, detailing its pros and cons, and rate 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?
