With so many different adverts on products and services it is easy to understand why people get so confused on what works best. Here we look at some of the details.

Teeth whitening has grown to become big business and the amount of companies offering products and services has grown. It is impossible to review all of these companies in one article but let us discuss the different systems and methods that are on the market.

When the teeth have been whitened they look amazing and this can have some really positive effects on your everyday life. People with whiter teeth smile more and this in turn make anyone you meet return the gesture and this can open doors in your love life as well.

The way whitening works is pretty similar and that is because of how the teeth become stained in the first place. The teeth have micro pores which open and close and soak up staining components placed in the mouth over a long period of time. So the good news is the teeth do not change quickly and for most of us can take three, four years or longer to notice a change.
When we age the enamel wears and a combination of accumulative staining will make us recognise our teeth have yellowed in coloured and we need to take action to whiten them. Things like smoking, red wine and coffee and tea are some of the main culprits to worsening the situation.

One of the questions that gets asked a lot is why some people of the same age have such differing colours of the teeth and the answer really is down to three things. Firstly what is the natural colour of the dentin which sits underneath the enamel. This cannot be changed through whitening or dental health. Secondly is down to how absorbent the teeth are to components placed in the mouth and some people are more likely to staining than others. The last reason is that the enamel has differing thickness so someone who has particularly thick teeth are less likely to get staining than someone with thin enamel.

When it comes to the different system then really we need to understand how the whitening process works. The enamel needs to be soaked in a whitening component to allow the pores to open and release the staining. Once this has been achieved the teeth will appear whiter in colour.

This soaking process needs to last at least twenty to sixty minutes at a time to really make the thing work otherwise no change will happen. Now the stronger the gel the better the result and less time you need to keep the product on the teeth for. For this reason we need to put aside products like mouthwashes and toothpastes because they are not on the surface of the teeth long enough to make a real difference. Enhancing your dental health of course but whitening the teeth then they are not going to make a significant difference.
