Coffee is one of the most popular drinks in the world, loved for its intense flavour and stimulating effects. But have you ever heard that coffee makes your teeth yellow? In this article, we’re going to debunk this belief and explain to you whether coffee is really responsible for yellowing teeth.
Coffee and its effects on teeth
Coffee is a beverage with a high concentration of tannins. Tannins are plant compounds that have an affinity for porous surfaces such as tooth enamel. When you drink coffee, the tannins attach themselves to the enamel and penetrate slightly into the microfissures or pores on the surface of the teeth. This gives the teeth a yellow or dull tint.
However, it is important to stress that coffee is not the only factor causing yellowing of the teeth. Poor oral hygiene is also a key factor. If you don’t brush regularly or if you neglect scaling, flossing and rinsing, plaque deposits and coffee pigments accumulate more easily.
What makes teeth yellow?
Smoking is another major factor that aggravates yellowing of the teeth. Substances present in tobacco smoke, such as nicotine and tar, tend to deposit on the teeth. In addition, cigarettes can contribute to bad breath, which you might want to get rid of. Other pigmented drinks, such as tea and red wine, also contribute to yellowing of the teeth. Tea also contains tannins, like coffee, and can have similar effects on tooth colour. Red wine, on the other hand, contains pigments called chromogens, which can stain teeth over time.
So, does coffee really make teeth yellow?
In short, although coffee contains tannins that contribute to yellow teeth, it is not the only culprit. Poor oral hygiene, smoking and the consumption of other pigmented drinks all play a part in staining teeth. But don’t panic, we’ve got a few tips to help you combat yellow teeth. By looking after your teeth, visiting your dentist regularly and adopting good oral habits, you can limit the effect of coffee on the whiteness of your smile.
