Why Our Dental Team Decided On Dentistry Without Amalgam

Through advanced technologies of dental adhesion, resins and state-of-the-art ceramics, the newest bonded restorations will be close to rivaling nature in strength, wear, function and appearance. With these new materials, it is possible to bond your teeth together again, practically restoring them back to their original strength minus the invasiveness of full-coverage crowns. In most instances, metal fillings may be replaced by methods that are known to be safer than mercury/silver amalgam fillings. It can be, therefore, possible to maintain the healthy, leftover tooth structure, instead of grinding it down for a crown.

Everything wears out, and your silver fillings will not be any different. They endure tense and significant biting forces each day, and as they age, they will break, leak and can also result in damaging fractures in teeth. After some time, metal amalgam fillings can actually soak up water, causing them to swell and even break free from the tooth. At this point, your tooth is much more liable to tooth decay and sensitivity.


Mercury/Silver fillings share some negatives worth listing that ought to be thought of when it is time to swap your restorations:

• Silver fillings are much less esthetic than natural-colored fillings. Think about it, they’re about as beautiful as large hunks of broccoli lodged in your smile.

• Amalgam expands and shrinks when exposed to cold and hot extremes within your mouth. The continuous expansion and shrinkage with temperature can easily initiate cracks as well as fractures in teeth. There may not be any symptoms for a while, yet these teeth may become hypersensitive as the crack increases or opens whenever you bite down or chew food. It’s not uncommon for patients to come in wondering the way they broke their tooth when they were eating something soft similar to a banana or slice of bread. What they don’t know is that the tooth almost certainly had a crack in it well before it eventually came apart.

• Silver fillings under regular chewing force are susceptible to metal fatigue or flexing and bending failure, a concept which can be fully understood and confirmed by continuously bending a metal paperclip until it finally breaks.

• Metal fillings are much harder and far less flexible compared to the teeth they’re wedged into. The longer they may be in the teeth, the greater pressure they will put on the rest of the weak outer surfaces of the tooth bringing about fractures and cracks.

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

• A tiny space surrounding the filling edge exists as soon as your silver filling is plugged into the tooth; and within this gap, constant leakage and corrosion takes place. This space is big enough to allow for bacteria and food particles to seep in after a while and result in tooth decay at the margin between the tooth and the filling. Composite fillings, however, are actually bonded to the tooth preparation area and seal the margins closed from invading bacteria.

• To be able to get a tooth ready for a composite filling, the actual tooth can usually be treated much more gently and with less healthy tooth structure needing to be removed. And therefore, the dentist can maintain the greatest level of healthy tooth structure as is feasible.

• Silver fillings necessitate drilling undercuts (think carving out a pumpkin) along with taking away more substantial good portions from the tooth in order to keep the mercury amalgam repair from falling out since it is not bonded directly to the tooth. Those undercuts can also compromise the tooth as fillings get more substantial and doom that tooth to subsequent fracture at some point. These fractures might be substantial resulting in crowning the tooth to repair it or even catastrophic fractures bringing about removal of the tooth.

• Composites, utilizing their opportunity to be conservative and making use of their gluelike attributes, may reinforce and guard against fracture. By simply blocking the chance of fracturing before experiencing the signs and symptoms of hot/cold sensitivity as well as biting pain, brand new conservative treatment options such as natural-colored fillings or porcelain-bonded restorations are actually reducing the unwanted effects of toothaches and broken teeth.

• Finally, many dentists say that, bonded tooth-colored restoratives are considered safer than classic fillings, since they do not have any mercury. While the American Dental Association (ADA) suggests the utilization of mercury in metal fillings is harmless, there is certainly an ongoing debate inside the dental field in regards to the side effects of those mercury amalgam fillings. Several of the European countries have banned the utilization of mercury amalgam fillings in order to avoid any hazards linked to mercury.

Given the menu of negatives associated, and potentially associated, with silver/mercury amalgam fillings, it becomes clear why patients are asking us to be PROACTIVE about replacement of mercury fillings as opposed to being REACTIVE and waiting until something goes wrong with the tooth.
