Factors Where Metal Free Fillings May Be a Good Option

Replacing your amalgam fillings with metal free fillings is a healthy choice. An amalgam filling is a mixture of different metals. The powdered metals in it are copper, silver, and tin. Liquid mercury binds all of them to form the filling. Many people are starting to replace their metal fillings with metal free ones. If you want to know what factors stress metal free fillings as better options, here are the details.

Non-reactive to temperature changes

Metal or amalgam fillings consist of copper, tin, silver, and mercury. Metals are sensitive to temperature changes. Having these fillings in teeth contract and expand while eating different foods. The constant expansion and contraction put pressure on the tooth. This results in microfractures and chips in the dental structure.

Metal free fillings stay the same from the point of application until the point of natural wear. These fillings do not expand or contract. Metal free fillings bond well to the tooth. It supports the tooth and does not ruin its structure.

Last longer than metal fillings

A metal filling often lasts about 10-15 years. The patient will have to think about the next type of filling by the time the amalgam filling comes off. Amalgam fillings tend to leave some damage to the tooth. The patient may need dental crowns to cover the damage. Metal free fillings stay on the tooth longer. These fillings even fill any microfractures in the tooth, if there are any.

Strengthen teeth

Metal free fillings bond to the tooth. Upon bonding, these fillings provide the tooth with more strength. Metal fillings cannot do this. The dentist applies these fillings in layers. One layer has to cure first before the dentist places the next one. The extensive curing makes the treated tooth stronger than it is.

Non-toxic

Elemental mercury is present in metal or amalgam fillings. It is a toxic metal. Mercury can cause harm to the kidneys and brain. Most dentists recommend replacing metal fillings with metal free fillings. This can enhance the patient’s dental and general health.

Almost invisible

Amalgam fillings are noticeable. The silver color even looks dark if there is not enough lighting. This often makes patients uneasy when smiling, talking, and laughing. Most patients want to replace their metal fillings with metal free fillings. Tooth-colored fillings are almost invisible and do not stand out from the rest of the patient’s natural teeth. These fillings protect and enhance the patient’s tooth at the same time.

Do not cause more decay

Metal fillings cause microfractures in the tooth. These serve as openings for bacteria. The bacteria will enter the tooth and eat away the remaining tooth structure. This will then worsen the fractures.

The fractures turn to cavities. Metal free fillings seal the tooth. They even go into the microfractures to hold the tooth together. Bacteria will not be able to enter the tooth to cause more damage.

Metal free fillings can improve your dental and general health

There is always a risk of having cavities. That is why dentists recommend dental fillings to repair the affected teeth.
