Periodontal Prevention and Treatment


Through the years, one of the questions that I have been asked the most is whether you should brush first or floss first.  I was always happy when people would ask that question because it made me realize that some people actually do floss at home. However, I never really had a good answer for that question. I would always say that if you flossed first, the spaces between the teeth would be cleaner for the fluoride toothpaste to penetrate between the teeth. But then I would say that if you brushed first, you would have the fluoride toothpaste in your mouth from brushing and the floss would pull the fluoride toothpaste between the teeth where a brush can't reach. And then I would sum it up by saying that there are probably benefits either way and it probably doesn’t matter that much which is done first.  I would always say that I was just happy that patients were attempting to floss

However, in May 2018 there was a research article published in the Journal of Periodontology, the publication that focuses on the treatment of gum disease and the tissues around teeth. The focus of this research article was to determine whether there was an advantage to brushing first or flossing first. The research concentrated on the reduction of plaque bacteria, the cause of gum disease and tooth decay, as well as fluoride retention on the tooth surfaces after either brushing first or flossing first. 

What they found was that flossing before you brush resulted in a statistically significant  reduction of plaque bacteria between teeth when compared to flossing after brushing.  So, that meant that flossing first did a better job of cleaning teeth in the research. In addition, flossing first also resulted in a statically significant increase in the amount of fluoride retained on the surfaces between teeth when compared to flossing after brushing. So, again, it is better to floss first because the teeth are left with more fluoride on them to help fight decay.  Here is a link to a summary of the article  https://www.perio.org/consumer/brush-or-floss-first

So now we have an answer based on science. 

It is better to floss BEFORE you brush your teeth.

Coming in for regular cleanings with one of our excellent dental hygienists will help keep your gums in great shape, but what you do at home matters as well. Brush twice daily and floss every evening. Our hygienists will be happy to show you good brushing and flossing technique.

Other steps you can take to prevent gum disease include:

  • Don't smoke or chew tobacco
  • Eat a healthy diet full of fresh fruits and vegetables
  • Use an antiseptic mouthwash. We'll be happy to recommend one.
  • If you have a health condition that can affect your dental health such as diabetes, heart disease, or cancer, please let us know so that we can take extra steps to help keep your gums healthy.
