Why Our Dental Team Decided On Dental Care Without Amalgam
Through modern day technologies of dental adhesion, state-of-the-art ceramics and resins, the newest bonded restorations are close to rivaling nature in durability, wear, functionality and appearance. Using these innovative materials, it is easy to bond teeth together again, practically restoring them back to their original toughness without the invasiveness of full-coverage crowns. Normally, metal fillings can be replaced by approaches which are a better solution to mercury/silver amalgam fillings. It is, therefore, possible to maintain the healthy, remaining tooth structure, as opposed to grinding it down for a crown.
Everything wears out, and your silver fillings are no exception. They endure stressful and heavy biting forces each day, and as they get older, they split, leak and may bring about damaging fractures on the teeth. Over time, metal amalgam fillings have the ability to soak up water, causing them to swell and even break away from the teeth. When this happens, your tooth is more liable to have tooth decay and sensitivity.
Mercury/Silver fillings have some other significant disadvantages that should be thought of when it is time for you to replace your restorations:
• Silver fillings are less esthetic than tooth-colored fillings. Everyone agrees, they don’t in the least resemble a natural part of the tooth.
• Amalgam expands and contracts when exposed to hot and cold extremes within your mouth. The continuous expansion and contraction due to temperature change can easily initiate cracks as well as fractures in your teeth. There will not be any kind of indicators for a while, yet these teeth may become very sensitive as the fracture expands or opens while you bite down or chew. It’s not uncommon for patients to come in wondering how they broke their own tooth when they had been eating something soft similar to a banana or a slice of bread. What they don’t know is that the tooth most likely had a fracture in it a long time before it finally came apart.
• Silver fillings that are under constant chewing stress are prone to metal fatigue or flexing and bending failure, a concept which may be grasped and confirmed by repeatedly bending a metal paperclip until it finally breaks.
• Metal fillings are harder and far less flexible than the teeth they’re molded into. The more time they are on the teeth, the more pressure they place on the remaining weak outer surfaces of the tooth leading to cracks and fractures.
• Metal fillings aren’t cemented to the cavity. They just sit in the tooth and react under pressure to wedge the tooth apart, like a metal wedge is used to split logs into firewood.
• A tiny gap around the filling edge exists as soon as the silver filling is plugged into the tooth and in this space, continuous leakage and corrosion occurs. This gap is large enough to allow for harmful bacteria and food particles to enter in with time and result in tooth decay at the margin between the tooth and the filling. Composite fillings, however, are essentially bonded to the tooth preparation area and seal the margins closed from invading bacteria.
• To be able to prepare a tooth for a composite filling, the tooth can usually be treated much more gently and with less healthy tooth structure needing to be removed. And thus, the dentist can maintain the greatest amount of healthy tooth structure as possible
• Silver fillings necessitate drilling undercuts (think carving out a pumpkin) and taking away larger healthy portions from the tooth in order to keep the mercury amalgam repair from falling out because it is not bonded right to the tooth. Those undercuts could also weaken the tooth as fillings get more substantial and doom that particular tooth to subsequent fracture at some point. These cracks may be significant resulting in crowning the tooth to restore it or perhaps catastrophic cracks leading to removal of the tooth.
• Composites, utilizing their opportunity to be conservative and making use of their gluelike properties, could reinforce and protect against fracture. By simply blocking the potential for fracture before experiencing the hassles of hot and cold sensitivity and biting discomfort, brand new conservative treatment options like tooth-colored restorations or porcelain-bonded restorations are reducing the complications of toothaches and damaged teeth.
• Finally, many dentists say that, bonded natural-colored restoratives are probably safer than conventional fillings, simply because they don’t include any mercury. Even though the American Dental Association (ADA) declares using mercury in metal fillings is safe, there is an ongoing disagreement in the dental sector in regard to the side effects of these mercury amalgam fillings. In Europe, several countries have banned using mercury amalgam fillings to avoid any kind of hazards associated with mercury.
When reviewing the laundry list of negative effects associated, and potentially associated, with mercury amalgam fillings, it’s no wonder that patients are asking us to be PROACTIVE about replacement of mercury fillings rather than being REACTIVE and doing something when the tooth fractures or hurts.
