| 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.
Q.2. Is whitening (bleaching) applicable to any kind of teeth?
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.
Q.3. My teeth have been gray since my infancy. Will they become white?
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.
Q.4. There are black stains on the back of my teeth due to tobacco nicotine.
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.
Q.5. How much time will be needed for cleaning? Also, how about post-cleaning
care?
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.
Q.6. Why will teeth become white as a result of bleaching?
Because oxygen arises from hydrogen peroxide liquid in the bleaching agent,
turning pigments into non-color substances through decomposition.
Q.7. Isn't bleaching painful? Also, isn't it harmful to the body?
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.
Q.8. There is a space between my front teeth, which is somewhat annoying
to me.
It is considered better if the space is covered with prosthetic materials
(laminate veneer or ceramic-metal crown).
Q.9. The color of the filler in my front teeth has changed. What should
be done?
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.
Q.10. My teeth have metal crowns, and my gums look blackish. Is there any
method to correct this condition?
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.
