Metal Free Fillings
Metal Free Fillings
When a new cavity needs a filling, our patients now choose tooth-colored composite fillings. Composite filings are a more attractive, conservative and stronger restoration than amalgam metal filings.
Amalgam metal fillings expand and contract with heat and cold. However, this constant contraction and expansion will cause the edges to wear down, leak and let bacteria into the tooth. Eventually, it will weaken the tooth walls and cause the filling and tooth to fracture.
Composite fillings are not affected by temperature as much so they are more durable under the wear and tear of daily use. Composite fillings bond to the tooth and have the ability to strengthen a weak tooth to a certain degree. They are also more conservative because we need to remove less healthy tooth enamel to prepare for them as compared to metal fillings.
Of course, just like a car needs repairs and eventual upgrades, fillings do as well – regardless of if they are metal or tooth colored fillings. When we see a leaking or cracked filling, we recommend being proactive and restoring it before it breaks further or causes pain. Depending on the size of the decay and the original filling, we may be able to restore the tooth with a new composite filling but if there is not enough tooth structure remaining to bond composite, a porcelain inlay, onlay or crown is indicated. We will always explain why we make a particular recommendation.
With excellent hygiene and preventive care, fillings can last for years. Metal free fillings conservatively restore your teeth and the beauty of your smile. Let us show you how!
Both of these pictures show how metal fillings will cause a tooth to fracture and break over time.
