Tooth colored fillings for a natural appearance.
Cavities are caused by weakened enamel. Today, cavities are less common than they used to be because of fluoride toothpaste, fluoride rinses and dental sealants. But cavities definitely still occur to both children and adults. A filling not only fills the hole in the tooth, but it stops the decay from spreading. If a cavity is not filled, the damage will continue and threaten to destroy the entire tooth. There are two different types of fillings available: traditional metal fillings and white or tooth colored fillings.
You might think that tooth colored fillings have only a cosmetic advantage, but they actually have many other advantages as well. Metal fillings are also called amalgam fillings because they are made of a mixture or amalgamation of different materials. One of those materials is mercury. Though fillings are not harmful to have in your mouth, mercury is an environmental toxin.
Tooth colored fillings are mercury-free.
Tooth colored fillings are also made from a mixture of materials, so they are sometimes called composite fillings. The mixture consists of a type of plastic or resin that adheres to the tooth. This gives composite fillings an advantage over metal fillings because they cannot fall out.
Before Dr. Whitman fills a cavity, the damage to the tooth must be cleaned, and a small part of the healthy portion of the tooth must be reduced to allow the filling to fit. Because metal fillings do not adhere to the tooth, a rather large pocket must be made in the tooth in order to make the filling secure. A composite filling does not need an expanded space because when it fills the cavity, it will adhere.
If you’ve ever had pain when eating from a metal filling coming in contact with metal utensils, you can be sure that won’t happen when you have resin tooth colored fillings.
There is no metal at all in tooth colored fillings; in fact, the material is the same that is used for cosmetic bonding, veneers and other dental work. Cosmetically, tooth colored fillings have a clear advantage. The material can be made to match the color of the tooth it is being applied to. In the end, it may be nearly impossible for anyone to tell that you have a filling. Metal fillings are a more economical choice, and they have been used for decades to fill cavities. They are proven safe. But the numerous advantages of tooth-colored fillings are making them the choice of many people today.
