Why Our Practice Decided On Dentistry Without Amalgam

With current technologies of dental adhesion, state-of-the-art ceramics and resins, the newest bonded restorations are close to matching nature in durability, comfort, function and look. Using these new materials, it is possible to bond teeth back together, basically restoring them to their virgin strength without the invasiveness of full-coverage crowns. In most instances, metal fillings can be replaced by techniques that are known to be safer than mercury/silver amalgam fillings. It is, therefore, possible to maintain the healthy, leftover tooth composition, rather than grinding it away to prep for a crown.

Almost everything wears out, and your silver fillings will not be any exception. They endure stress-filled and significant biting forces on a daily basis, and as they age, they crack, leak and may bring about damaging fractures on the teeth. Over time, metal amalgam fillings can, in fact, soak up water, causing them to swell and even break away from the teeth. When this occurs, your tooth is far more at risk of tooth decay and tenderness.

Mercury/Silver fillings have some other important detractions that need 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 don’t in the least resemble a natural part of the tooth.

• Amalgam grows and contracts whenever subjected to hot and cold extremes within your mouth. The constant expansion and contraction with temperature might initiate cracks and fractures in your teeth. There might not be any kind of symptoms for a while, yet these teeth may become sensitive as the crack increases or opens while you bite down or chew. It is not abnormal for patients to come in wanting to know how they broke their tooth when they were eating something soft such as a banana or slice of bread. What they don’t realize is that the tooth probably had a crack in it long before it finally came apart.

• Silver fillings under frequent chewing pressure are susceptible to metal fatigue or flexing and bending failure, a concept which is often grasped and shown by repeatedly bending a metal paperclip until it finally breaks.

• Metal fillings are harder and less flexible than the teeth they are wedged into. The more time they are on the teeth, the greater force they put on the rest of the weak surfaces of the tooth leading to fractures and cracks.

• Metal fillings are not cemented to the tooth cavity. They simply sit in the surrounding tooth and react under pressure to split the tooth apart, just like a metal wedge is used to split logs for firewood.

• A minute space surrounding the filling edge is present as soon as the silver filling is plugged into the tooth; and within this gap, constant leakage and corrosion takes place. This space is big enough to allow harmful bacteria and food particles to seep in with time and cause tooth decay at the joint between the tooth and the filling. Composite fillings, however, are actually bonded to the tooth surfaces and seal the margins closed from invading bacteria.

• In order to get a tooth ready for a composite filling, the actual tooth can be treated a lot more gently and with less healthy tooth structure needing to be removed. And therefore, the dentist can retain the highest possible amount of healthy tooth structure as is possible

• Silver fillings necessitate drilling undercuts (think carving out a pumpkin) and the removal of more substantial healthy parts out from the tooth in order to keep the mercury amalgam filling from falling out because it is not bonded right to the tooth. These kinds of undercuts might also weaken the tooth as fillings get bigger and relegate that particular tooth to subsequent cracking at some point. These cracks could be substantial resulting in crowning the tooth to restore it and even major cracks leading to extraction of the tooth.

• Composites, with their chance to be conservative and implementing their gluelike characteristics, could reinforce and protect against fracture. By simply intercepting the potential of cracking prior to experiencing the hassles of hot/cold sensitivity and also biting pain, brand new conservative treatments such as natural-colored restorations or porcelain-bonded restorations are stopping the negative effects of toothaches and damaged teeth.

• Finally, many dentists say that, bonded tooth-colored restoratives are safer than traditional fillings, given that they don’t have any mercury. Although the American Dental Association (ADA) claims using mercury in metal fillings is safe, there is certainly an ongoing disagreement within the dental sector regarding the side effects of these mercury amalgam fillings. In Europe, several countries actually banned using mercury amalgam fillings in order to avoid any kind of risks related to mercury.

Employing a PROACTIVE instead of a REACTIVE approach to amalgam extraction is really a choice quite a few patients hope to have Dr. Stone follow.
