Which Mouthwash is Best: Listerine or Crest?


When you brush and floss, we up our dental care and preventative oral care up to eleven with some mouthwash. It got us wondering: which is the best mouthwash? Which mouthwash works better? What are the differences between the brands?

We decided to compare the two most recognizable brands in mouthwash, Listerine and Crest.

Listerine vs. Crest


Listerine is synonymous with mouthwash. Introduced in the year 1879, Listerine is comprised of alcohol, preservatives and essential oils menthol, thymol, wintergreen and eucalyptus.

The most common experience people have when rinsing with Listerine is the burning sensation, caused by the alcohol. Drinking Listerine is also unadvised as it can cause intoxication or nausea.

There is also a concern among alcohol based rinses in that it causes oral cancer. The research on this concern is inconclusive, and the ADA says it is safe to use alcohol-based rinses.

Crest Pro-Health Mouthwash

Crest mouthwash is a recent addition to the mouthwash market. Most of Crest mouthwash ingredients lack the alcohol. For some of their products, it includes only a little, which is diluted in a water base. Crest mouthwash markets itself against the other brands of mouth as it contains fluoride. Fluoride is a mineral known for aiding in the prevention of cavities.

However, Crest Pro Health has its drawbacks. Crest mouthwash users claim of stains and a bitter aftertaste   

Fluoride is also found in municipal drinking water, so if a person drinks water normally, the fluoride in Crest’s mouthwash is not necessary.

Which is the best mouthwash?

At our Pacifica dental office, we see the mouthwash is best used after regular brushing and flossing. Crest Pro-Health or Listerine uses cannot remove every bit of plaque around and within teeth alone.

As for which toothpaste is best or which mouthwash is best, it mostly comes down to personal choice and experience. If you have a genetic predisposition to oral cancer, avoid using Listerine until more research is available. If you are the unfortunate few that have easily stainable teeth, avoid using Crest.
