|Q.1. What is dental esthetics?
It is possible to revert the color of teeth blacked or yellowed by tar, etc., to natural or further white, by applying a special pharmaceutical liquid or light to these teeth in so-called cleaning or whitening (bleaching). In addition, ceramics-based repair of spaced teeth or cut teeth and correction of upper and lower teeth, including cases of protruding lower teeth and double teeth, in such treatment as restoring beauty and functionality, will satisfy patients mentally and physically, pleasing them greatly.
Basically, it can be applied to any kind of teeth, as long as they are not crowned. Live teeth (living teeth) and nerve-removed teeth (non-living teeth) may be returned to white, beautiful teeth, without cutting. It may become impossible to whiten teeth more than a certain level.
It is believed that their color will become white to a certain extent through bleaching. In this case, however, laminate-veneering is recommended. If about six each of upper and lower teeth are laminate-veneered, that portion of your mouth will be brightened, and the impression of your face is expected to be changed.
Tar attaches to teeth not only from tobacco but also from coffee, tea, and various kinds of tea leaves. Particularly because the back side of teeth cannot be well brushed, tar may easily adhere to that side. Such tar or coffee stains can be removed using special liquids and through polishing in cleaning.
Time will depend on the number of teeth to be cleaned and on the state of staining, but it will be 30 to 40 minutes for three teeth. If tartar is attached, it will be removed in parallel.
Because oxygen arises from hydrogen peroxide liquid in the bleaching agent, turning pigments into non-color substances through decomposition.
It is not painful. Also, because the main ingredient of the bleaching agent is hydrogen peroxide liquid, which is used as a disinfection agent, there will be no side effects.
It is considered better if the space is covered with prosthetic materials (laminate veneer or ceramic-metal crown).
The filler whose color has changed is called composite resin, which assumes another color or becomes dirty through absorption of stain over years. If it can be replaced, have it done. If the scope of decayed teeth expands, however, it may be an excellent step to cover the portion with a ceramic metal crown, etc.
Conventional ceramo-metal crowns inevitably cause a blackish appearance of marginal portions of gums, because of the contraction of real gums or effects of permeating rays. To avoid this situation, the use of all-ceramic crowns or colorless crowns, with metal portions shortened and margin portions calcined with ceramics added, is recommendable.
