Replacement Of Old Metal Fillings
Metal fillings are often highly noticeable and can detract from the
beauty of your smile. However, the aesthetic disadvantages of metal
fillings are not the only reason to consider having them removed and
replaced. Our Arlington cosmetic dentist provides porcelain fillings,
inlays, and onlays for the replacement of metal restorations, and would
be happy to discuss this option with you during your regularly scheduled
If you live in or around Arlington and
would like to replace your old metal fillings, please contact Dental
Associates of Arlington or call (781) 648-0279 today to schedule an
appointment with our general dentist.
Reasons to Consider Replacing Metal Fillings
fillings do not look natural and can negatively impact the appearance
of your smile. In addition, metal fillings are not bonded to the tooth,
which can allow for them to come loose or fall out over time. Because
the amalgams used in metal fillings are prone to expand and contract
with temperature fluctuations in your mouth, metal fillings are likely
to cause internal damage to teeth as well.
As a practitioner of
holistic dentistry, our Arlington dental practice is concerned about
mercury content and other harmful substances in metal fillings. While
the debate over the harm caused by mercury in fillings continues, even
the chance of ill-effects is enough for our cosmetic dentist practice to
choose a metal-free dentistry practice. With this in mind, great care
is taken in removing metal fillings to help guard against the release of
mercury vapor during your appointment.
All Fillings Have a Life Expectancy
amalgam fillings are designed to last for about ten years. At that
point there’s a good chance that the cement holding it in place is
partially dissolved, which can make the filled tooth susceptible to
decay from within! If your metal amalgam filling is over ten years old
it’s definitely time to replace it!
We use tooth-colored dental
composite for our fillings. Made from a mixture of glass and plastic,
dental composite is the newest technology in dental fillings. It’s
safer, looks better, and acts more like real tooth. That’s just the
beginning of why composite fillings are the best choice!
Eliminate Potential Health Hazards
amalgam is a mixture of different metals with the main component being
mercury. While it hasn’t been proven conclusively that mercury in dental
fillings is dangerous to your health you still have a right to be
We can remove old amalgam fillings all while protecting
you from potential mercury dust or fumes that could be part of removal.
After it’s removed we can refill your tooth or we may place a crown,
depending on the health of the natural portion.
Composite Fillings Are Easier on Your Teeth
may not realize it but your teeth are actually slightly flexible. When
you chew your teeth bend to distribute forces evenly, but metal amalgam
doesn’t bend in the same way as natural teeth. The uneven distribution
of force can lead to microfractures in your teeth that put you at risk
for cavities and painful sensitivity.
Dental composite is
designed to behave just like natural tooth. It bends and flexes along
with your teeth to make the distribution of force perfectly natural and
safe. Your teeth will be able to do every bit of moving they need to
stay healthy and safe!
No Cement to Rinse Away Over Time
fillings don’t naturally bond with your teeth – they have to be
cemented in place. This leads to two problems: first is the need for
cement that wears out quicker than the amalgam itself, and second is the
need for larger fillings that use deep channels to help keep them in
When filling cement breaks off and rinses away you’re left
with small gaps between filling and tooth. These kinds of spaces are
the exact ones that bacteria loves to hide in and a cavity that starts
inside your tooth is unnoticeable and hard to treat! There’s also the
need for extra drilling in order to make the filling stay in place. That
means more healthy, natural tooth is lost to metal!
Composite fillings avoid both these problems. Not only are they
formulated to bond to your teeth but that bond means they can be made
only as large as the cavity demands! Unfortunately this doesn’t matter
when it comes to replacing a filling but it’s good news for any future
filling needs you have!
Eliminate Temperature Sensitivity
fillings conduct heat and cold – not fun when drinking coffee or eating
ice cream. Many patients who have amalgam fillings report sensitivity
for their entire lives. Replacing those metal fillings with composite
will finally grant relief, as the plastic and glass mix doesn’t conduct
temperature at all!
Tooth Colored Fillings
fillings are made from nontoxic and strong materials such as porcelain.
The materials used for white fillings is be bonded to the surface of the
tooth, preventing them from falling out. These fillings are not
impacted by heat or cold, and will not change shape or harm your teeth.
Replacing Metal Fillings Risks
fillings also know as dental amalgam or silver filling contains
elemental mercury. It releases low levels of mercury vapor that can be
inhaled. High levels of mercury vapor exposure are associated with
adverse effects in the brain and the kidneys.
FDA has reviewed
the best available scientific evidence to determine whether the low
levels of mercury vapor associated with dental amalgam fillings are a
cause for concern. Based on this evidence, FDA considers dental amalgam
fillings safe for adults and children ages 6 and above. The amount of
mercury measured in the bodies of people with dental amalgam fillings is
well below levels associated with adverse health effects. Even in
adults and children ages 6 and above who have fifteen or more amalgam
surfaces, mercury exposure due to dental amalgam fillings has been found
to be far below the lowest levels associated with harm. Clinical
studies in adults and children ages 6 and above have also found no link
between dental amalgam fillings and health problems.
limited clinical information about the potential effects of metal
fillings know as dental amalgam fillings on pregnant women and their
developing fetuses, and on children under the age of 6, including
breastfed infants. However, the estimated amount of mercury in breast
milk attributable to dental amalgam is low and falls well below general
levels for oral intake that the Environmental Protection Agency (EPA)
considers safe. FDA concludes that the existing data support a finding
that infants are not at risk for adverse health effects from the breast
milk of women exposed to mercury vapor from dental amalgam. The
estimated daily dose of mercury vapor in children under age 6 with
dental amalgams is also expected to be at or below levels that the EPA
and the Centers for Disease Control and Prevention (CDC) consider safe.
Pregnant or nursing mothers and parents with young children should talk
with their dentists if they have concerns about dental amalgam.
individuals have an allergy or sensitivity to mercury or the other
components of dental amalgam (such as silver, copper, or tin). Dental
amalgam might cause these individuals to develop oral lesions or other
contact reactions. If you are allergic to any of the metals in dental
amalgam, you should not get amalgam fillings. You can discuss other
treatment options with your Arlington dentist.
Replacing Metal Fillings with Composite
in modern dental composite materials and techniques increasingly offer
new ways to create more pleasing, natural-looking smiles. Researchers
are continuing their often decades-long work developing esthetic
materials, such as porcelain and composite compounds that mimic the
appearance of natural teeth. As a result, dentists and patients today
have several choices when it comes to selecting materials used to
replace metal filling repair, broken teeth or teeth with cavities.
advent of these new materials has not eliminated the usefulness of more
traditional dental restoratives, which include gold, metal alloys and
dental amalgam know as metal fillings. The strength and durability of
traditional dental composite materials continue to make them useful for
situations where restored teeth must withstand extreme forces that
result from chewing, such as in the back of the mouth.
Replacing Metal Fillings with Porcelain
metal filling also know as Amalgam, with porcelain depends on the metal
filling condition and your dentist's recommendation. They may be
replace for cast gold restorations, porcelain, and composite resins.
Gold and porcelain restorations take longer to make and can require two
appointments. Porcelain fillings, or white fillings, are esthetically
appealing, but require a longer time to place.
