While it is true that no one has naturally perfect white teeth, it is possible to have teeth that are clean-looking and bright. As we age, many factors can contribute to the development of stains on our otherwise bright smiles. No matter the natural state of your teeth, know that there are many options for teeth whitening in London. The specialists at London Holborn Dental Practice suggest you learn more about tooth stains and how they occur.
Tooth Discolouration and How it Happens
Yellowed, browned, or stained teeth are all forms of tooth discolouration. In the oral health industry, though, professionals typically classify these conditions in two different ways: extrinsic and intrinsic stains.
In many cases, extrinsic staining has a lot to do with a person’s habits. This type of tooth discolouration occurs right outside of the teeth.
People who have this kind of discolouration develop it due to their diet. The foods and beverages they regularly consume have a large impact on the colour of their teeth. Such food and drinks that cause staining include berries, soy sauce, coffee, tea, red wine, and soda.
Another major contributor to extrinsic staining is smoking. Cigarettes have many chemicals that are not only harmful to the body but can also lead to yellow teeth.
Your oral hygiene also plays a role in staining. Not brushing enough and brushing too hard can damage your enamel, leading to discolouration.
Intrinsic staining begins within the teeth and makes its way to the exterior. Intake of certain drugs, such as tetracycline, can lead to this kind of discolouration. Dental fluorosis – or the excessive consumption of fluoride – also gives rise to the darkening of the teeth.
This knowledge of the causes of teeth discolouration can help you minimise the changes over the years, but if you’re not satisfied with the shade of your natural teeth, professional whitening services can lighten your teeth to the shade you want.
