Is It Better to Floss Before or After Brushing? A Dentist Explains
The question of whether to floss before or after brushing your teeth is one of the most common debates in oral hygiene. Everyone seems to have an opinion, but what does the science say? Establishing a consistent daily oral care routine is the most important step for healthy teeth and gums. However, the order in which you complete each step can make a difference in how effective your efforts are.
Understanding how brushing and flossing work together helps clarify the best approach. Brushing is designed to clean the broad surfaces of your teeth, removing plaque and food particles from the front, back, and chewing surfaces. Flossing targets the tight spaces between your teeth and beneath the gumline, areas your toothbrush bristles simply cannot reach. Getting the sequence right ensures you get the maximum benefit from both activities.
The Case for Flossing First
Many dental professionals recommend flossing before you brush. The primary reason for this is that flossing dislodges food particles and plaque that are stuck between your teeth. Once these bits of debris are loosened and brought out from their hiding spots, brushing can effectively whisk them away along with the plaque on the main surfaces of your teeth. If you brush first and floss afterward, some of the plaque and food particles you remove from between your teeth may remain in your mouth until your next cleaning.
Another significant advantage of flossing first is improved fluoride exposure. Most toothpastes contain fluoride, a mineral that strengthens tooth enamel and helps prevent cavities. When you floss before brushing, you clear out the interdental spaces, allowing the fluoride from your toothpaste to reach more of your tooth's surface area. This ensures that these vulnerable, hard-to-reach spots receive the full protective benefits of your toothpaste, leading to a more thorough and effective cleaning.
Why Some People Prefer to Brush First
On the other hand, some people find it more satisfying to brush first. This approach clears away the bulk of the plaque and food debris from the larger tooth surfaces, which can make the subsequent flossing feel cleaner and more focused. For some, starting with a freshly brushed mouth makes the flossing process more pleasant and encourages them to be more thorough, as they are not dealing with as much initial buildup between their teeth.
The choice can also come down to personal habit and what feels most effective for you. If brushing first motivates you to complete your entire oral hygiene routine without fail, then that is a valid approach. The ultimate goal is to do both brushing and flossing consistently and correctly every day. While the "floss-first" method has some clear scientific advantages, the best routine is the one you will stick with day in and day out.
The Professional Consensus and What Matters Most
While you will find proponents for both methods, recent studies and the general consensus among dental professionals lean toward flossing before brushing. The primary benefit is the effective removal of dislodged plaque and the enhanced distribution of fluoride. By cleaning between the teeth first, you prepare the entire tooth surface for the final, comprehensive cleaning that brushing provides. This sequence helps ensure that your mouth is as clean as possible.
Ultimately, the most critical factor for your oral health is not the order, but the consistency and quality of your routine. Whether you choose to floss before or after brushing, what truly matters is that you are doing both every single day. Proper technique is also vital. Remember to brush for two full minutes with a soft-bristled brush and use about 18 inches of floss to clean thoroughly between each tooth. A consistent, well-executed routine is your best defense against cavities and gum disease, along with regular dental checkups every 6 months.
Frequently Asked Questions About General Dentistry
How often should I see a dentist for a checkup and cleaning?
For most patients, we recommend visiting the dentist for a routine checkup and professional cleaning every six months. These regular appointments allow us to monitor your oral health, identify any potential issues like cavities or gum disease in their earliest stages, and perform a thorough cleaning to remove hardened plaque (tartar) that regular brushing and flossing can't eliminate. Depending on your individual oral health needs, your dentist may recommend a different schedule.
What are the signs of a cavity?
The signs of a cavity can vary depending on its size and location. Common symptoms include tooth sensitivity to sweet, hot, or cold foods and drinks; a persistent toothache or spontaneous pain; visible holes or pits in your teeth; and brown, black, or white staining on any surface of a tooth. In some cases, a cavity may not cause any symptoms at all, which is why regular dental checkups are so important for early detection and treatment.
