White Fillings Phoenix
Phoenix white fillings have been done
for many years by Phoenix cosmetic dentist Dr.
Arthur Chal. Silver fillings
don't actually have that much silver in them. They're more correctly
called silver amalgam fillings. They're a combination of about half
mercury and the rest is mostly silver and tin.
Some people are concerned about the potential health
effects of mercury that is in your mouth. But beyond that, there are
several advantages of the white fillings:
 |
They bond to the tooth, thus
helping to strengthen your tooth. Amalgam fillings weaken the teeth,
which may then fracture later in life. |
|
|
They're made out of composite,
instead of metal, which means that they don't conduct the heat and cold
to the center of your tooth. This makes them more gentle to your tooth. |
|
|
They require less drilling away of
healthy tooth structure. Amalgam requires a certain thickness to be
strong enough, and requires that the inside of the cavity be made wider
than the outside, so that the filling stays in the tooth. Composite,
since it bonds to the tooth, can be placed after the decay is removed.
No healthy tooth structure has to be drilled away to get the filling to
stay, and no minimum thickness of filling material is required. |

The white fillings look much nicer. |

You never have any odd metallic
taste in your mouth from them.

Here are photographs of some old amalgam fillings
that were replaced by Dr. Chal. The photographs on the left show the beautiful
white fillings that he placed. Once you get used to not having the black
in your mouth, you begin to appreciate all the advantages of the
composite. |

Notice in the amalgam filling on
the middle tooth how there is a fracture line in the filling. Fracture of the fillings and fracture of the
teeth tends to be less of a problem with the white fillings. They bond to
the tooth and give a stronger overall result. |
Dr. Chal has been doing white fillings for many
years, and is expert in placing them. Most dental schools are still geared
toward teaching the placing of amalgam fillings. Many dentists feel
uncomfortable with placing composites on back teeth, and so they continue
to place the amalgams. The technique for placing them is difficult, and
much more meticulous. If composites aren't placed properly, they can lead
to risky sensitivity in the teeth, or they can deteriorate quickly.
However, if they are done properly, they are the most comfortable of
fillings and are very strong and long-lasting. |
