There are nowadays several different tooth whitening products and procedures being used, and in this article we’ll take a brief look at how these different processes work. We’ll also take a look at what your options are as far as treatments are concerned, and we’ll also touch on the safety aspect of each treatment. As is to be expected, there are a few possible risks and side effects, but this is something you encounter with practically any medical or cosmetic procedure. For example, pregnant women are advised against tooth whitening treatments, but of course this doesn’t mean everyone should avoid them.
Tooth whitening products do of course have an effect on tooth enamel, and of course tooth enamel is crucial for protecting the inner core of teeth against wear and tear. The reason why teeth become stained is because when we chew food, the enamel starts to erode, and this leads to the formation of micro-cracks in which debris tends to collect.
Additionally, ageing and tooth trauma can also result in stains occurring on the interior of a person’s teeth. These stains can however be successfully removed with tooth whitening treatments, but with that said, they are quite difficult to remove, and they will often require extended treatment times.
The active ingredient in practically all tooth whitening solutions will either be carbamide peroxide or hydrogen peroxide. Basically, both these ingredients begin to break down when exposed to oxygen, and as a result, the stains to which they are applied will also begin to break down. When the solution is removed from the enamel, the stains can then be readily removed.
There are three treatment options that you will have when considering tooth whitening. The first is the in-office procedure. This procedure lasts only about an hour and uses a concentrated peroxide gel that is painted onto the teeth and then activated with a special blue light that speeds oxidation.
The at-home treatment uses a less concentrated gel that is placed in custom-fit trays that fit your teeth. This solution is left on for 30-60 minutes once a day. Over the counter treatments are the cheapest option and most readily available treatment.
These treatments can be found at most drug stores, and of course they contain a much less concentrated solution. Over-the-counter treatments work best when used after a professional whitening treatment.
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.
People who experience tooth sensitivity can find relief by using an over the counter “sensitivity” toothpaste. In some cases however, people may also experience gum irritation and discomfort along the edges of their gums.
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.
Damage to the enamel is extremely rare, and if it does happen, it can usually be reversed by using remineralizing toothpaste. This sort of damage can be avoided completely if you follow your dentist’s instructions.
There have been no findings of permanent tooth damage with any whitening treatment, and it is considered a safe procedure.
