Why Our Practice Decided On Dentistry Without Amalgam
With modern technologies of dental adhesion, state-of-the-art ceramics and resins, the newest bonded restorations are actually close to rivaling nature in strength, wear, function and look. You can see side-by-side examples in the photo above of bonded white fillings vs. metal amalgam fillings. With these new materials, it is easy to bond your teeth back together, virtually restoring them back to their original toughness but without the invasiveness of complete-coverage crowns. Generally, metal fillings may be replaced by materials which are a better solution to mercury/silver amalgam fillings. It is, as a result, possible to preserve the healthy, leftover tooth structure, instead of grinding it away to prep for a crown.
Everything wears away, and your silver fillings will be no different. They endure tense and heavy biting forces on a daily basis, and as they get older, they crack, leak and may also bring about damaging fractures on the teeth. After some 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 more vulnerable to decay and tenderness.
Mercury/Silver fillings share some other important detractions that need to be thought of when it is time to replace your restorations:
• Silver fillings are much less appealing than tooth-colored fillings. After all, they don’t look anything like real teeth.
• Amalgam expands and shrinks when subjected to hot and cold extremes inside your mouth. The constant expansion and shrinkage through temperature may set off cracks and fractures in your teeth. There might not be any sort of symptoms for a while, but these teeth may become very sensitive as the fracture increases or opens when you bite down or chew. It isn’t abnormal 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 realize is that the tooth most likely had a fracture in it well before it ultimately came apart.
• Silver fillings under regular chewing pressure are prone to metal fatigue or flexing and bending failure, a concept that may be grasped and confirmed by continuously bending a metal paperclip until it finally breaks.
• Metal fillings are much harder and less flexible than the teeth they’re plugged into. The longer they may be on the teeth, the greater pressure they place on the remaining weak outer surfaces of the tooth bringing about fractures and cracks.
• Metal fillings aren’t cemented into the cavity. They just sit in the tooth and act under pressure to split the tooth apart, just like a metal wedge is required to split logs into firewood.
• A tiny gap surrounding the filling edge is present from the moment the silver filling is plugged into the tooth; and in this gap, normal corrosion and leakage takes place. This gap is large enough to allow for harmful bacteria and food particles to seep in after a while and lead to decay at the crack between the tooth and the filling. Composite fillings, however, are essentially bonded to the tooth surface and seal the borders closed from invading bacteria.
• To be able to prepare a tooth for a composite filling, the tooth can usually be treated a great deal more gently and with less healthy tooth structure needing to be removed. And therefore, the dentist can maintain the greatest amount of original tooth structure as is possible
• Silver fillings necessitate drilling undercuts (think carving out a pumpkin) as well as the removal of larger healthy parts from the tooth to be able to keep the mercury amalgam repair from falling out since it is not bonded directly to the tooth. These undercuts might also compromise the tooth as fillings get more substantial and sentence that particular tooth to upcoming fracture at some point. These cracks might be significant leading to crowning the tooth to fix it or even major cracks bringing about extraction of the tooth.
• Composites, with their chance to be conservative and making use of their gluelike qualities, may reinforce and protect against fracture. Through blocking the opportunity for cracking before experiencing the hassles of hot/cold sensitivity as well as biting discomfort, new conservative treatment options such as tooth-colored restorations or porcelain-bonded restorations are actually protecting against the unwanted effects of toothaches and broken teeth.
• Finally, in many dentists’ opinions, bonded tooth-colored restoratives are probably safer compared to traditional fillings, simply because they don’t contain any mercury. Although the American Dental Association (ADA) states the utilization of mercury in metal fillings is safe, there is an ongoing discussion inside the dental industry regarding the negative effects of those mercury amalgam fillings. Many European countries actually prohibited the utilization of mercury amalgam fillings in order to avoid any sort of risks related to mercury.
Employing a PROACTIVE instead of a REACTIVE method to amalgam replacement is really a choice a lot of patients would expect to have our practice follow.
