What causes yellow teeth and how to avoid it

  • By Regenerate Enamel Science

Stained teeth which have lost their natural whiteness can be an unpleasant problem, but with the right oral hygiene and a few lifestyle changes, you can take steps to prevent yellow teeth and ensure the longevity of your smile. Here we'll share our top tips for how to prevent yellow teeth, but don’t forget if you are worried about your teeth to book an appointment to discuss it with your dentist. 

What causes yellow teeth? 

Unsurprisingly, the teeth we see on TV and in adverts are not 100% natural, and it is highly unusual for teeth to be perfectly white. Although it is normal to have off-white teeth, yellow teeth can interfere with the look of your smile, so it’s important to know what makes teeth yellow. The main reasons for yellow teeth include the following:

  • Smoking causes your teeth to become stained and develop a yellow hue.
  • Not maintaining good oral hygiene can cause your enamel to become eroded, exposing the yellow layer underneath called dentine.
  • Some foods that make your teeth yellow – for example, curries, berries and sugary foods – contain lots of acid, leading to enamel erosion.
  • Certain drinks such as fizzy drinks, citrus fruit drinks, tea, and coffee are not only naturally staining, but also contain sugar and acid, which can lead to enamel erosion and teeth yellowing.
  • Everyday wear results in your enamel gradually wearing down over time. Your enamel can’t restore itself; therefore, your teeth become yellower with time.

  • Maintain a healthy, balanced diet.
  • Use products that protect and strengthen your enamel, for example, Regenerate Enamel Science range.
