They may have developed this vision from a combination of natural instincts about what healthy teeth look like and impressions gained from social interactions and the media. If they think their smile does not match up, this can lead to a lack of confidence. They could get an improved look and a boost to their self-esteem from teeth whitening in Belfast.

There are different reasons why someone might need teeth whitening in Belfast. Some of these are genetic and inevitable but others can be controlled. Even discolouration that occurs naturally will often respond to a brightening procedure. A dentist, like Blue Sky, can offer advice on keeping teeth looking fresh and clean after a whitening treatment.


Simply put, what someone puts in their mouth comes into contact with their teeth and affects them. If they repeatedly ingest foods that are likely to stain or darken the teeth, this will show. It’s even more likely to cause issues if they also have a lax or inefficient dental hygiene routine. Foods and drinks that stain the teeth include:

  • Red wine
  • Coffee and tea
  • Blueberries and blackberries
  • Pasta sauce
  • Citrus

As a guide, people need to consider the idea that if something is hard to get out of clothing, it’s going to stain the teeth as well.


A change in the colour of the teeth is a natural part of the ageing process. This is usually because, over time, the enamel on the outside of the teeth begins to break down through wear and tear. This exposes the dentin layer underneath and this is yellow in colour. The more it shows through the enamel, the yellower the teeth will look.

Medication and Chemicals

These have been known to cause a different type of stain. Extra fluoride in the water, for example, can cause the teeth to grow with intrinsic stains. These are part of the make-up of the teeth and, as such, are unlikely to respond to teeth whitening in Belfast. Fortunately, there are other methods that someone with intrinsic stains can consider bringing bright uniformity to their smile.
