In order to answer how long it takes to whiten teeth, we need to take into consideration a few things. Teeth whitening were known as teeth bleaching in the initial days when this technique was developed for the first time. Bleaching usually meant whitening teeth beyond its natural shining whiteness whereas teeth whitening that we know today is a somewhat milder version of the same technique.
As teeth bleaching required a bleaching agent containing higher percentage of peroxide, it quite often led to enamel coating damage. Also the whitening effect though quick to show, gave rise to complications like sensitive teeth. In the modern version of the same formula that was used for bleaching, the whitening gel contains lesser percentage of hydrogen peroxide, but it is more effective and long lasting.
The whitening kits available on the market are so effective that by the end of 3rd or 4th session you get a shining white set of teeth. Within a week to 3 weeks the results are guaranteed. However some other factors like the age of the user also plays a role. Younger users normally report very fast result whereas those over 50 may take longer. As the natural texture of teeth is distorted over a period of time, for some old users whitening may take up to 2 months.
Teeth whitening kits normally come with clear instructions about how to use and how long it will take to whiten your teeth. The enamel coating of our teeth works as a protective layer for teeth. Teeth whitening Products that come with whitening gel cleans the surface without damaging the enamel coating. It is normally recommended to wear the gel filled trays for 15 to 30 minutes for best results. However if you do not have sensitive teeth, the longer you wear it the quicker will be the results.
