6 Causes of Yellow Teeth Stains

illume - Frequent swimming or drinking a lot of soft drinks are habits that cause teeth to stain.


Drink soft drinks regularly

Sodas are sugary, and they can break down tooth enamel, making teeth weak and dull. For good teeth, you should drink iced tea. Most teas contain malic acid, a powerful bleaching organic compound that increases saliva production, which in turn, prevents tooth decay and prevents teeth staining.

Swim frequently

Many people’s favorite summer destination is the swimming pool. However, if you swim for more than 6 hours per week, you will most likely notice brownish accumulation due to chemicals in the pool water causing stains on your teeth.

Using the wrong mouthwash

Mouthwash is supposed to give you good breath, but you should check the label before buying. Certain ingredients in mouthwash can react with food staining compounds, which, instead of lightening the teeth, can dull the teeth. Choose those that do not contain the ingredients chlorhexidine or eucalyptol and only use a mouthwash before bed.

Use a bristle brush

Using a stiff brush will not make your teeth whiter, but in fact brushing too hard can erode tooth enamel. This will make the teeth more susceptible to cavities and yellowing. Dentists recommend using a soft toothbrush and replacing it every 3 months.

Use a lot of spices

Adding seasoning to food adds flavor and aroma to the dish, but can also stain teeth. Some highly pigmented spices like curry can turn teeth a yellowish color. If you want to add flavor to your dishes, try herbs such as turmeric, thyme, cinnamon … to protect your oral health.


Under a lot of pressure, some people instinctively grind their teeth to relieve stress. In addition to causing headaches and jaw pain, tooth grinding can weaken tooth enamel, making teeth yellow and brittle.
