Do You Have a Cavity? Get Dental Fillings

If you just found out that you have a cavity, you may be wondering how we plan to treat the issue. Fortunately, through routine cleanings every six months we are more likely to detect these issues when they are only a slight inconvenience rather than a serious problem. Having a cavity is no fun but a dental filling can restore the tooth after decay has been removed.
A dental filling uses special material to fill the spaces where decay has been removed to restore the tooth to its nature appearance and strength. While the tooth-colored resin used for a dental filling may also be used for purely cosmetic reasons such as hiding a small discoloration, chip or gap between your teeth, in most cases a dental filling is used to treat a cavity.
If you have a cavity, the first thing we will need to do is remove the decay. We will first numb the area with numbing gel and then local anesthesia so that you don’t feel any discomfort during your procedure. Next, we will use a dental drill to remove the decaying areas of your tooth. Once we have checked to make sure all decay has been removed then we will begin to rebuild the tooth using a dental filling.

Types of Fillings

There are two broad categories of dental fillings: metal fillings and tooth-colored fillings. Each may offer particular advantages and disadvantages in certain situations.

Metal Fillings

Amalgam — The classic “silver” filling in use for more than a century, dental amalgam is actually an alloy made up of mercury, silver, tin, and copper. The mercury combines with the other metals in the amalgam to make it stable and safe. These fillings are strong and inexpensive, but also quite noticeable. They also require relatively more tooth preparation (drilling) than other types.

Cast Gold — Among the most expensive restorative dental materials, cast gold combines gold with other metals for a very strong, long-lasting filling. It is also highly noticeable, which can be considered a plus or minus.

Tooth-Colored Fillings

Composite — A popular choice for those who don't want their fillings to show, composite is a mixture of plastic and glass, which actually bonds to the rest of the tooth. Composites are more expensive than amalgam fillings, and the newer materials can hold up almost as long. Less drilling of the tooth is necessary when placing composite as compared to amalgam.

Porcelain — These high-tech dental ceramics are strong, lifelike, and don't stain as composites can. They are sometimes more expensive than composites because they may require the use of a dental laboratory or specialized computer-generated technology. While considered the most aesthetic filling, they can also, because of their relatively high glass content, be brittle.

Glass Ionomer — Made of acrylic and glass powders, these inexpensive, translucent fillings have the advantages of blending in pretty well with natural tooth color and releasing small amounts of fluoride to help prevent decay. They generally don't last as long as other restorative materials.

What to Expect After Getting a Filling

The numbness caused by your local anesthesia should wear off within a couple of hours. Until then, it's best to avoid drinking hot or cold liquids, and eating on the side of your mouth with the new filling. Some sensitivity to hot and cold is normal in the first couple of weeks after getting a tooth filled. If it persists beyond that, or you have any actual pain when biting, it could signal that an adjustment to your filling needs to be made. Continue to brush and floss as normal every day, and visit the dental office at least twice per year for your regular checkups and cleanings. And remember, tooth decay is a very preventable disease; with good oral hygiene and professional care, you can make your most recent cavity your last!
