http://youtu.be/qpp7g_xEm7E In this video Caroline Short from Smile Tech gives a very brief description of how Carbamide Peroxide is used in teeth whitening treatments. Caroline explains that trays are often used with Carbamide Peroxide, which breaks down into the purer form of Hydrogen Peroxide after application and that Carbamide Peroxide is often a home treatment that a Dentist will send a client home with because of the legalities surrounding hydrogen peroxide in the UK
Teeth whitening has become an increasingly popular treatment in the UK over the last 5-10 years and there are now many ways in which we can remove the staining and discolouration that builds up on our teeth over time. When you think about teeth whitening the first thing that comes to mind is probably the Dentist chair and the uncomfortable looking set-up with the cheek retractor and the cold blue light. Although there are many other forms of tooth whitening products like whitening toothpastes, gels and trays and many other home care ranges to choose from.
Because most people do not understand the science behind the process of teeth whitening they often have to go through a process of trial and error with different products. A tip to the Dentist is often very expensive (for the in house professional laser teeth whitening) and in light of this the Dentist may recommend a slightly less expensive solution to a client with a teeth whitening problem. This may involve the use of trays at home, and the gel in the trays may well be Carbamide Peroxide.
But what is Carbamide peroxide teeth whitening? How does it work? A Carbamide Peroxide teeth whitening treatment is an effective and proven way of whitening or bleaching the teeth. There are two major types of tooth whitening gel — one is called a reductant and the other is called an oxidant. Carbamide Peroxide is part of the oxidant family and uses an oxidizing method to break down the staining within the tooth this oxidising method essentially bleaches the teeth. Research has shown that Carbamide Peroxide is a simple and effective substance to use in teeth whitening, as with most other teeth whitening gels the appearance of this substance is clear and sticky and will stick to the teeth when applied.
The reason that Dentists will often use Carbamide peroxide for home teeth whitening treatments is due to the legalities surrounding the re-sale of hydrogen peroxide. The European Union dictates what is deemed safe and unsafe for human consumption and use when it comes to the use and selling of hydrogen peroxide — very recently legislation changed and now it has been agreed that levels of 6% or less hydrogen peroxide in a whitening gel is safe for use in teeth whitening. A Dentist, therefore is taking a risk if they are sending a patient home with anything above 6% hydrogen peroxide for home use — because the client would administer this themselves. For this reason they send people home with other substances, like Carbamide Peroxide — which are a derivative of Hydrogen Peroxide and will break down into Hydrogen Peroxide when applied to the teeth. The strength of these gels is measured in percentages and different strengths are suitable for different types of whitening, be it laser whitening or chair side in house whitening. The cost of a hydrogen peroxide and a carbamide peroxide gel is very similar and it all depends on whether you go for a brand name.
It is essential that you choose a reputable teeth whitening product — either Carbamide Peroxide or Hydrogen Peroxide — because this will ensure you get a good result. As previously stated, people generally tend to us Carbamide peroxide tooth whitening gel at home because of the legalities surrounding the sale of hydrogen peroxide for home use. You should be wary of the concentrations which can range from 44% Carbamide Peroxide — the strongest level you can get and equates to about 18% hydrogen peroxide. To 22% carbamide peroxide which equates to around 8% hydrogen peroxide — which will still offer you a good result at home but is much gentler that
Most Dentists will still use high levels of hydrogen peroxide in house to get the best result — Zoom whitening for example has a level of about 35% hydrogen peroxide.
Again, whether you choose to get the Carbamide Peroxide teeth whitening gel or a Hydrogen Peroxide teeth whitening gel — always ask your Dentist wither at a practice or at your specialist teeth whitening provider. Your Dentist will be able to give you all of the information you need about these products and suitableness for you. http://samsteeth.wordpress.com/
There are also side effects to consider in teeth whitening, if you have sensitive teeth then go for a lower level (or percentage) of hydrogen peroxide or carbamide peroxide treatment. This will give you less pain and sensitivity. You can use a de-sensitizer pre-treatment and you can speak to your Dentist about these.
