“When talking about evidence and studies, it’s important to distinguish between the terms ‘flossing’ and ‘cleaning between teeth’,” says Henry Clover, chief dental officer at Denplan. “Floss, whether it’s tape or string, is only one of the methods to clean between teeth and some studies have shown that traditional floss is not always effective for some people. This is partly due to patients not always being able to use the floss correctly and the fact that a thin piece of floss might only remove a proportion of plaque and food particles between teeth. There is, however, strong evidence* to show that other methods of cleaning between teeth, such as interdental brushes, are highly effective in removing plaque and helping to prevent or treat gum disease.
“Tooth brushing only reaches around 70 percent of tooth surfaces, so if you’re not regularly removing plaque from in between your teeth, there will be bacteria building up and potentially causing problems. This includes an increased risk of gum disease, tooth decay and bad breath.
“It’s vitally important that patients don’t misinterpret the US government’s recent withdrawal of the recommendation to floss as a message that they only need to brush their teeth, and never clean in between them. We would strongly urge patients to follow an evidence based approach and continue to clean between their teeth, as advised by their dental team, using whatever method work best for them, be it floss, interdental brushes or waterpiks.”
