Mouthwash: Good or bad for your teeth?

Mouthwash: Good or bad for your teeth?

Posted on May 27, 2015

For some of us, mornings just aren’t the same without a good swig of minty mouthwash.

Fresh breath in the morning… It’s a great way to start the day and that mint freshness really shakes us out of any sleepy state.

Most of us believe mouthwash helps to prevent gum disease and boasts other benefits too.

Our last post about got tongues wagging and as we mentioned in that post: It’s always important to check labels. When you check the label for most mouthwash varieties, you’re likely to find ingredients such as alcohol, triclosan, thymol and so on listed.

Like most things in life, there are both pros and cons to using mouthwash and we’re here to help you to sift through each.


  • Mouthwash helps in the fight against gum disease because an antibacterial mouthwash will target the gums and tooth sockets that can get inflamed or inflected due to plaque from bacteria and food that lingers on teeth.
  • It helps to tackle cavities because it’s thought that fluoride can reduce demineralisation and cavitations of the teeth.
  • Mouthwash can help to soothe canker sores (better known to most of us as ulcers) as it detoxes the impacted area and in turn, reduces the amount of bacteria present.


  • It has been linked to oral cancer although, it’s important to keep in mind that a lot of debate continues to range in this area.
  • Just as mouthwash can help cankers, it also has the potential to irritate these sores, particularly if the alcohol content is too high.
  • It’s not necessarily the answer when it comes to bad breath. While we tend to think mouthwash helps, it can be short-lived and if a patient does have poor oral hygiene and fails to brush effectively, no amount of mouthwash has the power to help.

Some other things to keep in mind

  • Not all mouthwash products are the same – It’s best to ask your dentist for advice as to which type of mouthwash is most suitable for your needs.
  • Mouthwash should never be used to replace brushing and regular flossing.

As is the case with all of your dental needs, the best thing to do is to make an appointment with your NovaDental dentist and have a discussion about your specific situation.
