WHY THIS DAY MATTERS

Why Flossing Day is Important

Flossing gives you fresh breath

Not only does flossing help keep your teeth looking their best, it can also give you fresher breath! Since food particles can get stuck between your teeth if left untreated, these leftover pieces can cause bad odors when they start to rot. Regular flossing will help make sure there aren't any nasty understandings hiding in hard to reach places.

Flossing prevents gum disease

Regular flossing is essential to maintaining proper oral hygiene as it helps remove plaque that can eventually lead to periodontal (gum) disease. Not only will flossing help your teeth stay healthy and free of decay, it's also a good way to prevent more serious conditions such as gingivitis and tooth loss.

Flossing improves overall health

Gum disease has been linked to several other serious illnesses, such as stroke, diabetes, heart attack and even cancer. So by making sure you're flossing regularly, you can not only improve your dental health, but protect yourself from more serious ailments as well.
