Tooth Whitening - The Dangers
Contrary to what you may believe, there are a number of tooth whitening treatments used nowadays
. In this article we'll take a look at how these different processes work, what your options are, and also at the safety of these treatments. Just as with all medical procedures, there are certain possible risks and side effects. Pregnant woman in particular are advised against going for tooth whitening during pregnancy, so shouldn't this maybe apply to everyone?
It's also worth remembering that whitening products essentially affect tooth enamel which is designed to protect the inner core of a person's teeth. Things such as chewing, tooth grinding, and various foods, all cause the tooth enamel to begin eroding, and this in turn results in minute cracks appearing on the surface. These tiny cracks are an ideal environment for debris and stains to accumulate.
The stains also have a tendency to form on the interior of a person's teeth. This is usually a result of ageing and/or trauma, but fortunately these stains can also be removed with tooth whitening. They are however more difficult to remove than regular stains, and in order to do so, you'll often require longer treatment times.
Carbamide peroxide and hydrogen peroxide are the active ingredients in practically all tooth whitening products. When these substances are exposed to oxygen they begin to break down, and when this happens, it also breaks down the stains on your teeth. This does not actually remove the stains, but when these substances are removed, these stains of then easier to get rid of.
If you intend going for tooth whitening, you'll find that there are generally three options available to you. The first option is an "in office" procedure which takes approximately one hour, during which you will have a concentrated peroxide gel applied to your teeth. The gel is then activated by means of a special blue light in order to speed up the oxidation process.
The second option is an "at home" treatment which uses a slightly less concentrated gel. The gel is then placed into custom made trays that fit over your teeth. These are then left in place for up to an hour each day. Over the counter treatments are of course the cheapest treatments and they're also easily obtainable.
These are easily found at any drug store and contain a much less potent solution. Typically, over the counter treatments are most effective when used after a professional whitening treatment for maintenance.
Irrespective of which whitening procedure you choose, it's important to remember that they're all carry very similar risks and side effects. Tooth whitening in general is considered to be an extremely safe procedure, providing it's done in the proper manner. Also, in order to achieve the best possible results, it's essential that you follow the manufacturer's directions to the letter.
Tooth sensitivity and gum irritation are the most common side effects, but both of these conditions will disappear as soon as treatment stops.
Tooth sensitivity can be managed with an over the counter sensitivity toothpaste. Gum irritation may include redness and discomfort along the edges of the gums where the peroxide gel can come in contact with the gum.
One should also try to avoid swallowing the peroxide gel, bearing in mind that it can be dangerous if you swallow more than the amount used in the average application. As with all medications, tooth whitening gel should be kept out of reach of children. If you do accidentally swallow a bit of gel, it won't have any adverse affect on your body.
Enamel damage is very rare, but can be avoided by properly following your dentist's directions. If the treatment is left on too long, enamel erosion can occur but can be reversed with the use of a remineralizing toothpaste.
The bottom line is; tooth whitening is known to be a safe procedure, and to date, there have been no cases of permanent damage reported.
