Q&A\Advice from experts\Dentist says to floss twice, but even once would be nice.

Byline: Compiled by Kevin Ainsfeld

What is the purpose of dental floss?

It removes food and plaque that has built up between the teeth and the area below the gum line.

Why is it important to floss?

Your toothbrush cannot get to these places to remove the bacterial byproducts. Plaque can develop and eventually will turn to tartar. In serious cases, tooth loss can develop and the jaw can be damaged.

How often should you floss?

Ideally, dentists would like patients to floss twice a day but would be satisfied with once after dinner or just before bedtime.

Why don't more people floss?

Most people are lazy. They don't want to take another minute or so cleaning their teeth. They also don't know how to floss correctly - even though patients are usually instructed on how to floss during dental appointments. The correct way is to slide the floss through the contact point between each tooth. Each side of the tooth should be rubbed up and down before gently pulling the floss out and repeating until all the teeth are done.

What does it mean if my gums bleed when I floss?

Plaque and tartar has built up and cannot be removed just by flossing. When this happens, a visit to the dentist is needed so it can be removed. However, sometimes a little bleeding is common because of the rubbing of the gums. Just rub gently.

What is the best kind of dental floss to use?

Waxed floss, a wider waxed tape and a newer easy-glide floss are all quite useful in getting between the teeth. Unwaxed floss is not recommended because it can shred easily.
