Stains on teeth: what they are, the types, causes and treatments

A smile has the power to brighten up a whole room, but over time, it is natural for its radiance to fade. Tooth discoloration – which can manifest as stains on your teeth, spots or marks on teeth – is likely to affect us all at some point in our lives, impacting the self-esteem of even the most confident amongst us.

In this article, we explore the different factors which contribute to teeth discoloration. We also discuss what exactly stains on teeth are, their causes, preventative measures (including how to avoid them) and possible solutions, such as the Impress professional whitening service.

Whether you love a cup of coffee, are into your red wine or are simply interested in keeping that smile of yours in tip-top condition for as long as possible, you can find out what leads to tooth discoloration and reveal exactly how to keep your teeth bright and shining.

What are stains on teeth?

Tooth discoloration, often referred to as stains on teeth, is the gradual process of yellowing or the dulling colour of teeth that can affect your smile over time. It is also common for light- or dark-coloured marks to appear on the teeth as a result of staining.

Consuming certain foods, drinks and medications, as well as other factors like smoking, dental injuries and poor oral health are often responsible for tooth discoloration.

What causes stained teeth?

You may be wondering what exactly causes teeth to stain. A range of factors can lead to stained teeth, some of which fall within our control, whilst others lay beyond it.

Avoidable causes of stained teeth

• Dark-coloured food and drinks: Over time, coffee, tea, berries, red wine and soy sauce all contribute to staining teeth – which may be something to consider next time you make a cuppa.

• Smoking and tobacco use: Teeth discoloration is more widespread amongst those who smoke and use tobacco, as proven by extensive research.

• Poor oral hygiene: An adequate oral health routine is crucial to preventing teeth stains. Lack of proper brushing and flossing results in stains clinging to dental plaque, which can cause tooth discoloration over time.

• Excess exposure to fluoride: Although fluoride is important in protecting us against tooth decay, being exposed to too much whilst the teeth are still developing can cause fluorosis, which manifests as white spots on the tooth’s surface.

Unavoidable causes of stained teeth

• Genetics: Every smile is unique. Due to genetic diversity, each and every one of us has teeth of different shades, brightness and translucency.

• Dental trauma: Accidents, like falls, motor incidents or sports-induced injuries happen unexpectedly, causing trauma to the teeth that can result in staining.

• Ageing: As time goes on, our teeth undergo a natural transformation. When the enamel starts to thin, more of the dentin beneath, which is of a yellow colour, begins to be exposed. This results in teeth appearing darker or duller as we age.

• Dental treatments: The materials used for certain procedures, such as silver fillings, can lead to the surrounding teeth to appear greyish in hue. Furthermore, tooth-coloured fillings and the surface of teeth beside them can also stain after root canal treatments.

• Health conditions: A number of health conditions can lead to tooth discoloration, including liver diseases and eating disorders.

• Medication side effects: Some antihistamines and high blood pressure medication, amongst others, contribute to teeth staining. Discoloration can also be caused by taking antibiotics like tetracycline or doxycycline as a child.

• Cancer treatment: One of the side effects of cancer treatments like chemotherapy and head-neck radiation is tooth discoloration, as the reduction in saliva production causes teeth to stain.

So how can you maintain and restore our smile’s natural brilliance? The first step to making informed decisions about your dental hygiene is recognising the many factors that lead to stained teeth.

Why do my teeth stain so easily?

Porous enamel, resulting in coloured pigments from food, drink and tobacco being more easily absorbed, causes some people’s teeth to stain more quickly than others. Smoking, levels of acidity and poor oral hygiene, as well as genetics, can also have an impact, leading to teeth staining more easily.
