Metal has been utilized in dental work for many years, and only 25 years ago a dentist would have placed a metal filling without hesitation. However, research has indicated that metal dentistry can have immensely damaging effects. Mercury and other metals used in this practice can have severe effects on health. These materials are toxic and can therefore cause oxidative stress and nephrotoxicity. The usage of metal in dental work has been a serious topic of debate.
There are several reasons why metal fillings can be damaging. Temperature changes can affect the metal, and these changes can weaken the tooth. The weakening of tooth structure can cause bacterial infection and decay. Placement of metal fillings requires removal of tooth structure, which can cause chipping and fractures.
There are also substantial advantages to metal-free dentistry, and the practice is quickly replacing metal usage. Composite fillings are made of resin, which contains either glass or plastic. Resin fillings are more visually appealing because they are tooth-colored, and they are also safer and more beneficial for health.
Composite fillings are extremely tough compared to metal ones. They are more effective in tooth repair because they act as an adhesive that helps maintain the tooth structure. This renders the excessive removal of tooth for the filling placement unnecessary. Composite fillings are also more inexpensive and less time consuming to place. They don’t cause periodontal disease or tooth discoloration.
Zirconia crowns are another example of effective metal free dentistry. These crowns are made from zirconium, which makes them robust and durable. They are attractive because of their resemblance to natural teeth, and they don’t require significant tooth structure removal for placement. They are also modifiable and biocompatible. They are sturdier than porcelain crowns, which are known to chip.
Metal-free dentistry is also advantageous because it is versatile. Composite fillings can help repair chips, breaks, and wear and tear in teeth, in addition to their use in fillings cavities. They help maintain tooth structure, look attractive, and don’t have toxicity or other health damaging properties.
