Why Are Your Teeth Not Pearly White?

Teeth discolouration conceptIt doesn’t matter how regularly you brush; your teeth still don’t look white enough. Even when you’ve tried whitening toothpaste, your teeth still don’t appear as white as you’d like.

Several reasons can cause teeth discolouration. Some dentists are known for professionally whitening teeth in London, and the common reasons they find responsible for this issue include the following:

What You Eat or Drink

Perhaps the most common reason behind discolouration is what you consume. Some fruits and vegetables, and dishes made with them may affect tooth colour. Drinks like coffee, tea and wine are also guilty of the same.

Tobacco Use

Smoking or chewing tobacco products typically causes discolouration and the multiplication of bacteria in the mouth (due to tobacco’s mouth drying effect).

Not Taking Care of Your Teeth

Not brushing at least twice a day with fluoride toothpaste, not flossing and not visiting your dentist for cleaning may also cause a dull, yellowish or dark colour on your teeth.

Some Diseases

Some conditions may affect the hard, outer covering of your teeth called enamel, or the softer surface under it called dentin. A baby in the womb of a mother who has an infection may also grow discoloured teeth.

Some Medications

Some medications and treatments also affect tooth colour, such as chemotherapy, taking antibiotics and others.

Trauma to the Tooth

A blow to the face may affect the colour of growing teeth in children, but trauma may also darken the teeth of an adult.

Excess Fluoride

Fluoride is good for strengthening teeth, but if you have too much, it can lead to discolouration. For instance, if the water in your area contains high levels of fluoride.

Having your teeth whitened professionally more than once a year may lead to discolouration. If you keep experimenting with whitening gels, strips or toothpaste, this may also have the opposite effect.


In some cases, thicker enamel runs in the family.

Getting Old

Dentin has a natural yellowish colour. As you get older, your enamel wears away, and your dentin begins showing through.

Some of these causes are avoidable, and some are not. Fortunately, however, your dentist may have a way to deal with your problem with tooth discolouration, whatever may have caused it.
