We think there are many reasons why you may want to whiten your teeth. It can give you a younger appearance, can boost your confidence no end and can reverse years of everyday staining that has built up on your teeth.

A great looking smile makes a good first impression as it sends the message that you like to take care of yourself and your oral hygiene. You might even have a special event such as a wedding, birthday, or school reunion that you’d like to whiten your teeth for. Whatever your reasons behind going for teeth whitening, you’ve taken that step, and it’s the first step to a more confident you.

Let’s look first at why your teeth need whitening in the first place. There are some reasons behind teeth staining, such as:-

Food and Drink

Coffee, tea and red wine are all major factors for teeth staining. The strong colour pigments called chromogens attach to your tooth enamel.


The tar and nicotine from smoking create stubborn stains on your teeth. Tar is naturally dark. Nicotine is colourless until it’s mixed with oxygen, then, it turns into a yellowish, surface-staining substance.

Below the enamel of your teeth is a softer area called dentin. Over the years, the enamel gets thinner with brushing, and the more yellow-coloured dentin starts to show through.

Injury or Trauma to the Teeth
Sometimes if you have been hit in the mouth or have fallen over and hit your tooth, it can become discoloured. Because the tooth reacts with the impact; it creates more dentin, which is a yellowish colour, which makes the teeth appear more yellow.

If you are taking certain antibiotics, antihistamines and anti-hypertension medication, a possible side effect can be tooth discolouration. Children who are exposed to antibiotics like tetracycline and doxycycline when their teeth are forming (either in the womb or as a baby) may have discoloration of their adult teeth later in life.

Top tips

  • It is important to be able to ask any questions you would like to, even if you think they are obvious questions. You could ask about various types of teeth whitening they offer, what results you can realistically expect from those treatments and how long the whitening effects of the treatment are likely to last.
  • Also, ask them if there are any particular risks related to your teeth, such as increasing the sensitivity of the teeth.
  • It’s a good idea to talk to other people who have had the same treatment or visit another dentist for a second opinion until you feel fully confident with the treatment you are going to opt for.
  • Always ask for a written treatment plan and price estimate before going ahead, so there are no nasty hidden cost surprises.

Teeth whitening isn’t permanent. It can last from a few months to up to three years, but this varies from person to person. The whitening effect won’t last as long if you smoke or drink red wine, tea or coffee, which as mentioned earlier are all factors in staining your teeth.
