Benefits of teeth whitening at iStomatolog
Why do teeth become dark and what are reasons for their staining?
Extrinsic staining within dental enamel. It can be caused by long-term smoking, frequent drinking of tea, coffee, red wine and herbal teas, as well as application of some medications (for example, based on chlorhexidine).
Intrinsic staining, discoloring of the enamel and dentin which is adjunct tooth tissue. The reasons can also vary from congenital diseases to injuries, consumption of certain drugs (for example, tetracycline antibiotics), dental fluorosis, hypo and hyperplasia, age-related changes of tooth tissues, etc.
But the most common reasons are:
- A) previous treatment of root canals with pastes based on resorcinol-formalin (gray-pink teeth);
- B) uncured chronic nerve inflammation (gray-brown colored teeth).
In both cases, the tooth tissue is saturated with a pigment from the inside. Therefore, the whitening process is more complex and time consuming, while the initial color restoration can be impossible.
So, how to whiten your teeth?
Products used for whitening have peroxide and carbamides in their composition. But we have heard of "laser whitening", "ozone whitening of" and so on. And what is the difference?
It should be understood that there are various mechanisms for activating a whitening gel, such as:
Whitening Systems with a Light-Activation Source
- ultraviolet (Zoom1/2/AP, Philips),
- blue light (Luma Cool, LumaLite, USA)
- laser whitening (Biolase, USA)
Whitening Systems with Chemically Activated Mechanism
- the most popular is Opalescence XtraBoost, Ultradent, USA.
In general, the principle of action depends on gel composition and comes down to splitting the peroxide molecules and releasing the oxygen molecules, which results in dissolving pigments in dentin and enamel tissues. This process is the chemical essence of discoloration ("whitening" is rather a commercial term).
For whitening, it is necessary to put a whitening agent to the most pigmented part of a tooth. Thus, it is important to determine whether the nature of discoloring is external or internal. When it is external, the gel is applied on the tooth surface, while if it is internal, the gel is introduced into the cavity.
External whitening can be often effectively provided by professional teeth cleaning, but only upon condition it is performed regularly (at least once every six months). This method allows recovering tooth color to the initial condition, as well as removing dental plaque and tartar.
If a patient wants to have his teeth two or more shades lighter than their natural color, then tooth whitening is performed (for example, laser whitening).
