Flossing properly means gently guiding floss between your teeth, curving it into a C shape around each tooth, and cleaning slightly beneath the gumline with an up-and-down motion. The goal is to remove plaque and food debris from surfaces your toothbrush cannot effectively reach—not to force the floss into your gums.
The American Dental Association recommends cleaning between your teeth once a day with floss or another interdental cleaner. The right tool and technique may vary depending on the spacing between your teeth, your dental work, your dexterity, and your gum health.
If you are unsure whether you are flossing effectively, the dental hygiene team at South Florida Dental Care can demonstrate the proper technique and recommend a tool suited to your mouth. Call our Hollywood dental office at (954) 966-6410 or request an appointment online.
Why Cleaning Between Your Teeth Matters
Brushing twice a day is essential, but toothbrush bristles cannot clean every surface between tightly spaced teeth. Floss and other interdental cleaners help remove food debris and plaque—the sticky film of bacteria that continually develops on the teeth.
If plaque is not removed, it can contribute to cavities between the teeth and inflammation along the gumline. Plaque can also harden into tartar, or calculus. Unlike plaque, hardened tartar cannot be removed with a toothbrush or floss and requires professional dental instruments.
Daily interdental cleaning works together with brushing and professional dental hygiene care to help protect your teeth and gums. It does not replace regular examinations or professional cleanings.
How Often Should You Floss?
Clean between your teeth once every day. The best time is when you can make it part of a consistent routine. Morning, evening, before brushing, or after brushing are all acceptable as long as you clean thoroughly.
Some people prefer to floss before brushing so loosened plaque and debris can be brushed away. Others find it easier to brush first. Consistency and technique matter more than the order.
How to Floss Properly in Seven Steps
- Start with approximately 18 inches of floss. Wind most of it around one middle finger and a smaller amount around the middle finger of your opposite hand.
- Control a short section. Hold one to two inches of floss tightly between your thumbs and index fingers.
- Guide it gently between two teeth. Use a slow rubbing motion. Do not snap or force the floss into the gum tissue.
- Form a C shape around one tooth. Once the floss reaches the gumline, curve it against the side of the tooth.
- Clean the tooth surface. Keeping the floss against the tooth, gently move it up and down and slightly beneath the edge of the gumline.
- Clean the neighboring tooth. Before leaving the space, curve the floss in the opposite direction and clean the adjacent tooth. Each space contains two tooth surfaces that require attention.
- Continue around your entire mouth. Advance to a clean section of floss as you move between teeth, and remember the back surface of the last molar on each side.
The floss should contact the tooth without cutting into the gum. If it repeatedly shreds, catches, or becomes stuck in one location, let your dentist know. A rough filling, damaged restoration, tooth decay, or another condition may need evaluation.
Common Flossing Mistakes
Snapping the Floss Into the Gums
Forcing floss through a tight contact can injure the tissue between the teeth. Instead, ease it through with a controlled side-to-side motion.
Moving the Floss Only Through the Center of the Space
Simply pushing floss up and down between two teeth misses much of the plaque. Curve the floss around one tooth, then the other, to clean both surfaces.
Stopping at the Gumline
Plaque commonly collects where each tooth meets the gum. Slide the floss gently beneath the gum’s edge without forcing it deeply or causing pain.
Flossing Only When Food Feels Stuck
Flossing is not only for removing noticeable pieces of food. Plaque may remain between teeth even when the area feels clean.
Forgetting the Back Teeth
Clean between the molars and behind the final tooth in each row. These areas are easy to miss and hard to reach with a toothbrush.
Using Household Objects Between Teeth
Fingernails, paper, utensils, pins, and other objects can damage gum tissue or become lodged between teeth. Use a product specifically designed for interdental cleaning.
Choosing the Right Interdental Cleaner
Traditional string floss works well for many people, especially where the spaces between teeth are tight. However, it is not the only acceptable option. The most useful tool fits your mouth, cleans effectively, and can be used consistently without injuring your gums.
Waxed or Unwaxed Floss
Both can be effective. Waxed floss may slide more easily through tight contacts, while unwaxed floss may appeal to patients who prefer a thinner texture. Dental tape is broader and may feel more comfortable in wider spaces.
Floss Picks and Holders
These devices can make cleaning easier for people who find traditional floss difficult to control. They are also convenient when away from home. You still need to curve the floss against each tooth rather than moving it only through the center of the space.
Interdental Brushes
Small brushes may be useful in wider spaces, around certain dental restorations, or when gum recession has created more room between the teeth. Using the correct size is important because a brush that is too large may traumatize the gums.
Water Flossers
A water flosser directs a controlled stream of water between the teeth and along the gumline. It may help people with braces, bridges, dental implants, limited dexterity, or difficulty using string floss.
The best choice depends on your individual needs. A dentist or dental hygienist can explain whether a water flosser, interdental brush, floss threader, traditional floss, or combination of tools is appropriate.
How to Floss Around Bridges, Implants, and Braces
Dental work can change the way you need to clean between your teeth. For example, floss cannot pass directly through the connected teeth of a fixed bridge. You may need a floss threader, specialized floss, an interdental brush, or a water flosser to clean beneath the replacement tooth.
Dental implants and orthodontic appliances also require careful cleaning around areas where plaque can collect. Avoid forcing a tool that does not fit. Ask your dentist or hygienist to demonstrate the recommended method for your specific restoration or appliance.
Why Do My Gums Bleed When I Floss?
Bleeding may occur because inflamed gums are sensitive, because you haven’t flossed regularly, or because you snap or force the floss into the tissue. Don’t dismiss bleeding as normal during flossing.
Continue cleaning gently rather than scrubbing more aggressively. If bleeding persists, occurs frequently, or is accompanied by redness, swelling, tenderness, gum recession, bad breath, or loose teeth, schedule a dental evaluation. These can signal gum disease or another oral health concern.
Helping Children Learn to Floss
Children should begin flossing when two teeth touch and a toothbrush can no longer clean the entire space between them. An adult will usually need to perform or closely supervise flossing until the child has enough coordination to clean thoroughly, often around age 10 or 11.
Floss picks, or holders, may be easier for some children to control. The dental team can demonstrate a child-friendly technique and help parents choose the right tool.
Frequently Asked Questions
Should I floss before or after brushing?
Either order is acceptable as long as you brush and floss thoroughly. Choose the sequence that helps you clean consistently every day.
Is it better to floss in the morning or at night?
The time of day matters less than making interdental cleaning a daily habit. Many people prefer nighttime because it removes plaque and food debris accumulated during the day, but morning or midday flossing can also be effective.
Can a water flosser replace string floss?
A water flosser can be an effective interdental cleaner and may be especially useful around braces, bridges, implants, or for people with limited dexterity. Whether it should replace or supplement string floss depends on your teeth, gums, and dental work.
Is waxed or unwaxed floss better?
Neither is universally better. Waxed floss may move more easily between tight teeth, but both types can clean effectively when used correctly.
What should I do if floss keeps getting stuck or shredding?
Do not pull or force stuck floss through the gums. Gently work it free from the side. Repeated catching or shredding in the same location should be evaluated because it may be related to a rough restoration, damaged tooth, decay, or a particularly tight contact.
