One of the challenges with the whitening trays supplied by the dentists is the high level of sensitivity they create and as a result people do not complete the prescribed course they set out to achieve.
The reasons for this is that teeth whitening products placed on the teeth are designed to open the pores of the enamel to release staining being held in the micro pores. With the whitening trays this process occurs over a fourteen day period requiring them to be worn whilst you are asleep.
Now for deep level staining in the pores the trays can work very well and they slowly penetrate the staining over a sustained period but unfortunately the chance of getting sensitivity is also very high. This is because the micro pores stay open for the period you are using the trays and every day the trays are used the whitening gel will impregnate deeper and deeper and eventually this is what aggravates the nerve endings and causes the pain.
Customers then report the pain become so severe they stop after five to seven days just at the point when they trays start to remove the staining and therefore the whitening result is not as good as you would hoped when you embarked on purchasing the trays.
Sometimes it is worth trying to use the trays in four consecutive day periods and then having four to five days off before starting again as this will unlikely to give any sensitivity but will achieve the desired results just over a longer period.
After the initial period of wearing the trays and hopefully gaining the result you require it is worth noting the trays should be used regularly to remove staining that will re appear. Most dentists will supply refill gels but places like ebay will also supply cost effective options from all the top brands.
As a long term solution the trays are a good investment as long as you are disciplined and stick to a long terms plan of teeth whitening but just phase the initial use as this will give you results and a comfortable experience.
Some people just could not consider sleeping with the trays as the thought of having something in your mouth for seven to eight hours per night is just not viable and therefore treatments like laser teeth whitening can a sensible option to the trays.
This treatment takes just one hour and one visit and customers prefer to not have the hassle of having to do something every day which requires immense discipline!
One of the areas of discipline is not consuming staining components we enjoy on a day to day basis including smoking, coffee, curries, tea, etc. This sounds simple in practise but not having a cup of tea for two weeks or not enjoying a cigarette for two weeks is near on impossible.
Unfortunately if you do stick to a neutral diet for the time prescribed then you risk inserting more staining in to the pres of the enamel than you are actually removing and therefore the process does not work!
Either way what you decide with teeth whitening good luck and hope it works for you.
