Why Our Dental Team Provides Amalgam-Free Dental Care

Many patients come to our practice asking to update their silver fillings. They really want their old metal fillings removed and exchanged with tooth-colored fillings. Patients typically cite esthetic and health considerations with their metal fillings. It happens to be true that the esthetics of your smile could be dramatically improved with a more natural, tooth-colored repair. Additionally, there are numerous reasons that explain why it’s a good idea to update to a tooth colored porcelain restoration or a resin composite filling.

Almost everything wears away, and your silver fillings will be no exception. They withstand tense and significant biting forces every day, and as they age, they will split, leak and may also bring about damaging fractures on the teeth. Over time, metal amalgam fillings can actually absorb water, causing them to swell and even break away from the tooth. When this occurs, your tooth is far more at risk of decay and sensitivity.

Mercury/Silver fillings have some other important detractions that ought to be thought of when it is time to replace your restorations:

• Silver fillings are less attractive than natural-colored fillings. Everyone agrees, they don’t in the least resemble a natural part of the tooth.

• Amalgam grows and shrinks whenever subjected to hot and cold extremes inside your mouth. The continuous growth and shrinkage through temperature can easily initiate cracks and fractures in your teeth. There may not be any kind of symptoms for a while, but these teeth may become sensitive as the crack increases or opens whenever you bite down or chew food. It is not unusual for patients to come in wondering how they broke their own tooth while they had been eating something soft like a banana or slice of bread. What they don’t know is that the tooth most likely had a crack in it a long time before it eventually came apart.

• Silver fillings under continuous chewing pressure are prone to metal weakness or bending and flexing failure, a concept which may be understood and shown by continuously bending a metal paperclip until it finally breaks.

• Metal fillings are harder and less flexible compared to the teeth they’re molded into. The longer they are in the teeth, the more force they will put on the rest of the weak walls of the tooth bringing about fractures and cracks.

• Metal fillings aren’t glued to the tooth cavity. They merely sit in the tooth and act under pressure to wedge the tooth apart, just like a metal wedge is utilized to split logs into firewood.

• A microscopic gap surrounding the filling edge is present as soon as the silver filling is plugged into the tooth; and in this space, normal corrosion and leakage takes place. This unnoticeable gap is big enough to permit harmful bacteria and food particles to seep in with time and bring about decay at the border between the tooth and the filling. Composite fillings, however, are essentially bonded to the tooth surfaces and seal the margins closed from bacterial invasion.

• In order to prepare a tooth for a composite filling, the actual tooth can be treated far more gently and with less healthy tooth structure needing to be removed. And therefore, the dentist can maintain the maximum level of virgin tooth structure as is possible

• Silver fillings necessitate drilling undercuts (think carving out a pumpkin) along with removing larger healthy portions from the tooth in order to keep the mercury amalgam repair from falling out given it is not bonded right to the tooth. These kinds of undercuts might also compromise the tooth as fillings get more substantial and sentence that particular tooth to upcoming cracking later on. These cracks could be substantial resulting in crowning the tooth to fix it or perhaps catastrophic cracks bringing about extraction of the tooth.

• Composites, utilizing their opportunity to be conservative and implementing their gluelike properties, may strengthen and protect against fracture. By simply intercepting the potential for cracking prior to experiencing the hassles of hot and cold sensitivity and also biting discomfort, new conservative treatments such as natural-colored restorations or porcelain-bonded restorations are actually protecting against the side effects of toothaches and damaged teeth.

• Finally, many dentists say that, bonded natural-colored restoratives are likely to be safer than traditional fillings, simply because they do not contain any mercury. While the American Dental Association (ADA) suggests the usage of mercury in metal fillings is safe, there is an ongoing disagreement in the dental field regarding the side effects of these mercury amalgam fillings. Several of the European countries actually banned the usage of mercury amalgam fillings to avoid any kind of hazards associated with mercury.

When reviewing the list of negatives associated, and potentially associated, with silver/mercury amalgam fillings, it becomes clear why patients are directing our practice to be PROACTIVE about removal of mercury fillings as opposed to being REACTIVE and holding off until the tooth cracks or develops decay under the amalgam plug.
