Discolouration of Teeth.


The majority of the population does not naturally have teeth as pearly white and sparkling as those we see in celebrities and on tv, and this is completely normal. However, you can still have pearly white teeth and avoid discolouration and yellowing with some basic knowledge and care as well as a treatment from Philips Zoom Teeth Whitening with their dental in office treatments or at home treatments.

Discolouration can come in the form of darkening, developing white spots or turning to different shades. Although not considered medically dangerous, tooth discolouration can be disheartening or off-putting.

There are two main categories of discolouration, which are extrinsic and intrinsic.


Extrinsic is caused by anything that comes into contact with your teeth, affecting the enamel (the outer surface)

Intrinsic occurs in the inside structure of the tooth, the dentine, and is harder to treat.

The top offenders of discolouration include:

  • Drinks such as coffee, red wine and tea.

These acidic beverages help chromogens attach to the enamel and cause staining.

  • Dark-colored foods such as cola, chocolate, soy sauce and balsamic.

These contain a pigment-producing substance called tannin that sticks to the enamel and causes blemishes.

  • Smoking or chewing tobacco.

These chemicals create a yellowish stain on the tooth surface.


  • Excess fluoride found in certain water or overuse of toothpaste or supplements.

This can cause white streaks or dark spots on the teeth.

  • Medication:

Certain prescriptions of antibiotics can cause staining for children, as well as women over 4 months pregnant.


  • Genetics:

Certain people are born with thicker enamel or naturally whiter teeth.


  • Aging:

Over time, enamel thins, which makes teeth appear more yellow.


  • Trauma:

Trauma can also cause teeth to discolor

  • Diet:

If your diet is more acidic, leading to an acidic environment in your mouth, this too can make your teeth more prone to discoloring.



How to prevent and treat discolouration:

The best way to prevent discolouration is to watch the type and quantity of food and drink you consume. Knowing the effects of certain substances can allow you to limit and control the extent of color change. Fizzy drinks, foods high in sugar and carbohydrates and very acidic foods all tend to wear down the enamel and should be taken in moderation.

Good dental hygiene is important to maintain natural tooth color, as yellowing is caused by a buildup of plaque and tartar. Removing this build up before it decays will allow for healthier and whiter looking teeth.

Including more calcium into your diet, whether through certain food such as milk or broccoli, or with a supplement, can prevent enamel erosion as well as strengthen the gums of your mouth.

Therefore, while having a completely white and sparkling smile does not come naturally, there are various ways to avoid discolouration and ensure your tooth color remains at top quality and health at all times.

You can prevent tooth discolouration with regular professional cleaning and good home care.
