By Most of us believe we know how to brush our teeth a quick scrub morning and night, followed by a rinse and a splash of mouthwash.
However, dental experts warn that even the most consistent brushers could be making common mistakes that reduce the effectiveness of their efforts.
According to Dr. Praveen Sharma of the University of Birmingham’s School of Dentistry, about half of adults in the UK experience gum disease at some point, with bleeding gums being one of the first warning signs.
“If your gums are bleeding or swollen, it’s a sign you need to brush better,” he explains.
Along with regular dental check-ups, Dr. Sharma and the BBC What’s Up Docs podcast hosts, Dr. Xand and Dr. Chris van Tulleken, have highlighted four common brushing errors that, if corrected, could greatly improve oral health.
1. Brushing once thoroughly is better than twice hurriedly
The NHS recommends brushing twice daily, but Dr. Sharma emphasizes that quality matters more than frequency.
“If possible, brush properly twice a day,” he says. “But it’s better to do one thorough clean and one quick one than two rushed brushes.”
He advises prioritizing a proper brush and floss before bed, since plaque can build up overnight. For easier cleaning, interdental brushes can replace traditional floss.
Dr. Sharma recommends using small circular motions, covering every surface of each tooth, especially near the gum line.
Meanwhile, Dr. Xand advises being mindful while brushing not scrolling on your phone to ensure you’re doing it effectively.
2. Brush before breakfast, not after
While many people brush right after eating, Dr. Sharma cautions that this can harm enamel.
“Ideally, brush before breakfast,” he says. “If you brush after eating, wait a while, especially after acidic foods or drinks.”
Acidic items like fruit juice and coffee soften enamel, making it more vulnerable to wear if brushed too soon.
Dr. Chris suggests rinsing with water after eating to remove some acids, then waiting at least 30 minutes before brushing.
3. Don’t rinse after brushing
Many people rinse their mouths with water after brushing a habit Dr. Sharma says washes away protective fluoride.
“You should spit, but not rinse,” he advises.
Leaving a thin layer of fluoride toothpaste on your teeth allows it to continue protecting enamel. If you prefer to rinse, use mouthwash instead of plain water.
4. Expensive toothpaste isn’t always better
Despite the variety of whitening, charcoal, or “enamel-strengthening” toothpastes on the market, Dr. Sharma says price doesn’t determine quality.
“As long as your toothpaste contains fluoride, it doesn’t make much difference,” he explains. “I usually buy whichever brand is cheaper or on offer.”
Fluoride is the essential ingredient that prevents tooth decay and strengthens enamel. However, dentists may recommend specialized toothpastes for people with conditions such as sensitive gums.
