Yellow teeth: how to avoid them and whiten them ?

Dents jaunes : comment les éviter et les blanchir ? - Y-Brush

Who doesn't dream of having a bright smile with beautiful white teeth? However, our teeth are becoming unpleasantly yellow. Why do these yellow spots appear? Can yellowing of the teeth be avoided? How can you whiten your teeth?

Why do our teeth become yellow?

Having yellow teeth in your mouth is not always a sign of poor oral hygiene. Our teeth are not all the same colour. The original colours of the enamel range over 29 shades of the colour scale. This is why some people will naturally have whiter, more aesthetically pleasing teeth than others.

Yellowing of teeth occurs as a natural process. Enamel wears away with age. It becomes thinner and reveals the dentin, which is yellow.

There are other external factors related to our lifestyle that cause enamel wear and explain the yellowing of teeth. 

The main external causes of enamel wear are : 

  • A diet rich in sugary or acidic foods
  • Smoking and regular consumption of alcohol and coffee
  • Dental plaque that forms as a result of poor oral hygiene.

How to avoid yellowing of the teeth?

The natural ageing of the tooth, which affects its aesthetics, is irreversible. Our teeth naturally adopt these yellowish colours with age. However, it is possible to limit the premature wear of the enamel due to external factors.

The first piece of advice from the dentist, before proceeding with bleaching, is to adopt good dental hygiene. The golden rule of good oral health is to brush your teeth at least twice a day. There are a few tips to help ensure optimal brushing : 

  • Wait 30 minutes after each meal before brushing
  • Choose toothpaste carefully
  • Change your toothbrush at least once every three months
  • Use dental floss to wait for hard-to-reach areas 


In addition to a healthy dental routine, it is advisable to improve one's diet so as to limit tooth staining. This means cutting down on the consumption of foods that are too sweet and too acidic. You should also resolve to stop smoking and drinking certain beverages, such as coffee, so as not to damage the enamel quickly.

You can also use a Y-Brush toothpaste tube. Thanks to its fluoride-enriched formula, it effectively strengthens the tooth enamel, fights against the formation of cavities, combats plaque and acts against bacteria.  

How to whiten your teeth?

There are two ways to get whiter teeth. On the one hand, there are the old-fashioned remedies that you can apply at home and that are easily accessible. On the other hand, you could visit a dentist who will recommend the appropriate treatment.

Grandmother's remedies include the use of products such as vegetable charcoal, baking soda, or coarse salt and coconut oil. A home-made treatment is effective. But be careful not to overdo it as it can damage enamel and gums.

A dental practice offers several treatments for teeth whitening. Scaling is an essential treatment. The application of a hydrogen peroxide-based whitening gel gives you white teeth and a bright smile after a one-hour session. In addition, the dentist can offer an intensive polish, which brings instant results.

You can use the Y-Brush toothbrush which removes 15% more plaque than a traditional toothbrush. This means that you can achieve an almost immediate whitening result. 

We hope this guide has helped you understand what is causing your yellow teeth and what you can do to get a good teeth whitening.
