5 Common Tooth Brushing Mistakes That Are Damaging Your Smile—And How to Fix Them
Brushing your teeth is the most basic dental hygiene habit—but it’s surprisingly easy to do it wrong. Incorrect brushing techniques can result in enamel erosion, gum recession, and tooth sensitivity over time. Here are five of the most common brushing mistakes—and how to correct them for healthier oral habits.
1. Brushing Too Hard
Scrubbing vigorously doesn’t lead to cleaner teeth—instead, it can cause long-term damage. According to Colgate, brushing too hard wears down enamel and irritates the gums, often leading to sensitivity and gum recession. Colgate also states that if your bristles are frayed quickly, it’s a sign you’re brushing with excessive force.
Fix it: Use a soft-bristled toothbrush and light, circular motions to gently clean without abrasion.
2. Using the Wrong Toothbrush
Not all toothbrushes are equal. The ADA recommends using a soft-bristled brush and replacing it every three to four months—or sooner if it’s worn out. Brushes with hard bristles can damage enamel and gums.
Fix it: Choose a soft-bristled toothbrush that fits comfortably in your mouth. Don’t forget to replace it regularly.
3. Not Brushing Long Enough
Most people brush for under a minute, far below the recommended two minutes. A study in the Journal of Dental Hygiene found that brushing for the full two minutes removes up to 26% more plaque than brushing for 45 seconds.
Fix it: Use a timer, play a two-minute song, or opt for an electric toothbrush with a built-in timer.
4. Skipping the Gum Line and Tongue
Your teeth aren’t the only part of your mouth that need attention. Bacteria accumulate along the gum line and on the tongue. According to the ADA, neglecting these areas can lead to bad breath, gum disease, and plaque buildup.
Fix it: Angle your toothbrush at 45 degrees toward the gums and gently brush. Use a tongue scraper or the back of your toothbrush to clean the tongue daily.
5. Brushing Right After Eating
Brushing immediately after eating—especially acidic foods—can damage softened enamel. An ABC10 article reports that people should wait 30 to 60 minutes after eating before brushing. This allows saliva to neutralize acids and protect your teeth.
Fix it: Rinse your mouth with water or chew sugar-free gum, then wait at least 30 minutes before brushing.
Bonus Tip: Floss Before or After?
Flossing is essential for removing plaque and food between teeth, but many people wonder when to do it. According to the American Association of Orthodontists, flossing before brushing may remove more plaque and allow better fluoride access between teeth.
Fix it: Choose whichever order works for you—just make sure you floss thoroughly once per day.
