Brushing your teeth is an essential part of maintaining good oral hygiene, but it can be
frustrating when your breath still doesn’t feel fresh afterwards. While brushing removes
food debris and plaque from the surfaces of your teeth, bad breath (halitosis) can have
several underlying causes that brushing alone may not address.
Understanding where bad breath comes from can help you identify the cause and take the
right steps to improve it.
Common Causes of Persistent Bad Breath
One of the most common causes of bad breath is bacteria that accumulate on the tongue.
The rough surface of the tongue provides an ideal environment for bacteria to thrive,
producing sulphur compounds that create an unpleasant odour. If you only brush your teeth
and neglect your tongue, these bacteria remain behind.
Gum disease is another frequent cause. When plaque builds up around the gums, it can lead
to inflammation and infection. The bacteria associated with gum disease can produce a
persistent smell that is unlikely to disappear with brushing alone.
Dry mouth can also contribute to bad breath. Saliva helps wash away food particles and
bacteria, so when saliva production decreases, bacteria can multiply more easily. This may
occur overnight, as a side effect of certain medications, or in people who breathe through
their mouth.
In some cases, bad breath may be linked to factors outside the mouth, including sinus
infections, acid reflux, or certain medical conditions. If the problem persists despite good
oral hygiene, it is worth discussing with your dentist or GP.
What Can You Do?
If bad breath continues after brushing, consider the following:
- Brush your teeth twice daily with a fluoride toothpaste.
- Clean your tongue using a tongue scraper or toothbrush.
- Clean between your teeth every day using floss or interdental brushes.
- Stay well hydrated to reduce dry mouth.
- Attend regular dental check-ups so any gum disease or decay can be identified and
treated early.
