There is a common perception that teeth should be perfectly white, but this is often not the case in real life. Even if you brush your teeth every day, there are a number of reasons why your teeth may not be white.


Teeth are not white, to begin with

Firstly, the idea that teeth are inherently perfectly white is a myth. Even if teeth never come into contact with discolouring agents, they still appear slightly off-white in their natural state. The visible part of a tooth is made up of dentin and enamel. Dentin is the hard, dense tissue that forms the bulk of the tooth structure and is covered with enamel. Both of these parts cause the tooth to appear discoloured in real life. However, in a world where the teeth have never been exposed to anything else, dentin causes the teeth to appear greyish white.

In almost all cases, dentin is at least slightly stained and sometimes it is significantly stained. The enamel that covers the tooth is fairly clear, so when you look at their teeth you can see any staining that occurs naturally in human dentin. If you personally happen to have dark dentin, then no amount of basic surface whiteners will make your teeth completely white, as they are slightly stained, to begin with – and brushing will certainly not remove the colour.


Teeth whitening strips

Teeth whitening strips help to lighten the colour of your teeth. Each pack contains one strip for the upper teeth and one strip for the lower teeth. Depending on the type of product you use, these strips are removed at the end of the treatment, or they may dissolve in your mouth.


Most whitening strips consist of peroxide or bleach. They are made of a very thin plastic called polyethene. Once your teeth are in contact with the product on the strip, it will start to whiten your teeth. You will usually need to leave them on your teeth for 20 to 30 minutes to get the full whitening effect.

Brushing before treatment

You can brush before applying the whitening strips. However, you should be careful not to irritate your gums. The whitening treatment on the strips can further irritate the injured gums. In most cases, brushing gently before applying the whitening strips should be fine. If you have food and debris in your teeth, continue brushing. In most cases, leaving these bacteria in your teeth may do more harm than good. In addition, whitening agents will be less effective if there is debris on your teeth. Brushing before treatment helps the strips to stick to the teeth better.

If you decide to brush your teeth before treatment, it is best to wait at least 30 minutes after brushing before applying the whitening strips.


Brushing after treatment

You may need to brush your teeth after treatment to remove any residual chemicals from your teeth. Brushing after treatment will not change the whitening effect, but you should brush gently to avoid discomfort and gum irritation.
