Many people believe that rinsing their mouth after brushing is an essential final step in oral hygiene. However, according to Dr. Deepa Chopra, a dentist with over 18 years of experience at Whites Dental in the UK, this is a serious mistake that can negate the protective effects of toothpaste.
“Don’t rinse your mouth immediately after brushing,” warns Dr. Chopra. “While it may feel refreshing, it washes away the fluoride that helps prevent tooth decay and protects your enamel.”
She explains, “The residual toothpaste left on your teeth allows fluoride to continue its protective work. Simply spit out the excess paste and avoid rinsing.”
Using mouthwash right after brushing is another common mistake, according to Dr. Chopra, as it further washes away the fluoride. “If you wish to use mouthwash, do so before brushing or at a different time of day, such as after lunch.”

Additionally, Dr. Chopra offers some crucial advice for proper oral care:
Brush your teeth at least twice a day for a minimum of two minutes each time to remove plaque and prevent gum inflammation.
It is advisable to brush before breakfast as it stimulates saliva production, which is the mouth’s natural defense mechanism, and helps eliminate morning breath.
Wait 30 to 60 minutes after eating before brushing your teeth to avoid enamel erosion caused by food acids.
Don’t forget to clean your tongue, as it harbors the most bacteria responsible for bad breath.
“By understanding these simple facts and making a few small changes, you’ll see significant improvements,” emphasizes Dr. Chopra. “Caring for your oral health doesn’t have to be complicated; it just needs to be done correctly.”
