The Reality of Bad Breath in the UK
If you worry about your breath, you are far from alone. According to data from the Oral Health Foundation, around one in three people in the UK suffers from bad breath (halitosis) at some point in their lives.
While a garlicky dinner or a morning cup of coffee can cause temporary odours, persistent bad breath is usually driven by something else, such as bacteria. Millions of microscopic bacteria live in our mouths. When they feed on leftover food particles, they release volatile sulphur compounds (VSCs), which smell notoriously unpleasant.
Most of this bacteria hides in places your toothbrush simply cannot reach, deeply wedged between your teeth, tucked beneath the gum line, and layered across the back of your tongue. Over time, if this bacterial film (biofilm or plaque) isn’t thoroughly cleared away, it hardens into a rough substance called tartar (calculus). Tartar acts like a magnet for even more bacteria, leading to chronic bad breath and, ultimately, gum disease.
