Why should you brush your tongue when you brush your teeth?

• A. To remove plaque that can cause bad breath and bacteria growth
• B. To whiten teeth
• C. To prevent cavities
• D. To grow more taste buds

Answer: (A)

Brushing the tongue helps remove bacteria and debris that collect on its surface. Those bacteria can produce foul-smelling compounds and contribute to bad breath, so cleaning the tongue directly reduces odors and supports overall oral hygiene. Whitening the teeth or preventing cavities involve the tooth enamel and surfaces, whereas tongue brushing mainly targets odor-causing bacteria rather than whitening teeth or preventing caries. Growing more taste buds isn’t something brushing can do, so that idea isn’t correct. A gentle brush or tongue scraper used as part of your daily routine helps keep breath fresh and promotes healthier mouths.
