At Ora-Dent Dental Group we use tooth colored restorations rather than mercury or silver fillings. Silver colored fillings or amalgam has been the filling of choice for the past one hundred years, however recently research has shown that proper bonding does not always occur. Thus, these fillings can harbor odor-causing pathogens that overtime can cause decay of healthy tooth enamel. For this reason we use Porcelain inlays and restorations that match the color of your teeth, providing a more aesthetic and permanent result.
Disadvantages of Silver Fillings:
Amalgam or silver fillings actually contain combinations of different metals most notably silver and mercury. These metals are susceptible to wear and tear in the mouth and also can experience expansion and contraction due to slight temperature changes in the oral cavity. Due to these factors these fillings can easily break at the edges, creating spaces for food and bacteria to deposit.
In addition to this the mercury within the amalgam fillings can corrode or leak onto the teeth causing stains and damage to the teeth and gums.

Advantages to Tooth-Colored Restorations
The main advantage to using resin onlays includes matching tooth color for aesthetic appeal and also a tight bond that that can restore tooth structure. These fillings prevent future corrosion and breaks and have in fact been shown to increase the strength of the tooth remains.
In addition to the above benefits these resin fillings also contain fluoride that prevents future decay and also keep all placement adequately distant from the gum line. Respecting gum line margins is healthier for your gums.
Replacing silver Fillings with Tooth Colored Restorations
This process takes two appointments as described below.
In your first appointment we will remove the old filling and take an impression of your teeth. This impression will be sent to our lab and a temporary onlay will be placed until your next appointment.
The temporary onlay will be removed, and a conditioning gel will be placed in the space of your tooth. Next bonding cement is added and the new only placed. Lastly a high intensity UV light will be used to complete the bond.
