What are the side effects of Listerine?

In fact, mouthwash gets bad marks because it:
  • Irritates canker sores. If the alcohol content of your mouth rinse is too high, it may actually end up irritating the canker sore more than helping it.
  • Masks bad breath.
  • Has been linked to oral cancer.

Moreover, is using mouthwash bad for you?

The mouthwash is a dangerous short-term solution that really has no efficacy at all. Also, there are mouthwash products on the market that contain additional ingredients such as fluoride which can reduce the risk of tooth decay. The harsh alcohols can also help prevent periodontal disease, cankers and bad breath.

Is Listerine toxic?

Original Listerine contains 26.9 per cent alcohol, while the flavoured varieties contain 21.6 per cent. But alcohol intake is only one of the dangers of drinking the colourful mouthwash. “There's a lot of bad-sounding stuff in there,” said Hanley, mentioning methyl salicylate.

Is Listerine safe to use?

Some researchers are concerned that long-term use of products with alcohol may increase the risk of oral cancer, but the ADA says alcohol rinses are safe. The FDA also says the combination of ingredients in Listerine mouthwash is “generally recognized as safe and effective.”
