Everything You Need To Know About The Dental Cavity Fillings

One of the more common dental procedures is to get dental fillings. This treatment is often the first one recommended to deal with cavities. While it may seem intimidating to go in for a filling, it can alleviate anxiety to have useful and accurate information about the procedure before the visit.
 

Filling Cavities: What to Expect


You should expect to be at your dentist's office for around an hour. This gives him or her enough time to take x-rays if needed, talk to you about the procedure and complete the dental work. Before filling cavities, your dentist will numb your teeth, gums, and surrounding skin to avoid and lessen discomfort during the procedure. Next, he or she will drill out the decay in the tooth and replace it with a filling. This process only takes a few minutes.

Once you're done, your mouth will probably remain numb for a few more hours. There aren’t any significant risks associated with filling cavities but be sure to keep your dentist’s contact information on hand in case you have any questions or complications.

The most common use of tooth fillings is to fill a cavity in the tooth. But tooth fillings also can be used to repair damage to teeth caused by teeth grinding (bruxism) or to replace part of a broken tooth.

Types of Cavity Fillings


Many options are available for tooth fillings, and all of them have their pros and cons. Types of tooth fillings include gold, silver amalgam (a composite of mercury, silver, and other metals), tooth-colored composite material, porcelain, and a special type of glass. The best tooth fillings for you will depend on cost, what your insurance may cover, and your aesthetic preferences.
There is a wide variety of materials used for filling cavities and they vary in strength and color. The two most common types are amalgam and composite.
  • Amalgam Fillings: Amalgam has been used by dental professionals for more than a century; it is the most researched material used for filling cavities. Amalgam fillings are strong and are therefore ideal for filling cavities in the back of the mouth such as in the molars, where chewing takes place. Since they are made of a combination of several metallic elements, amalgam fillings can be noticeable when you laugh or smile. These fillings are among the least expensive of all cavity-filling materials.
  • Composite Fillings: Sometimes referred to as composites or filled resins, these fillings feature a combination of glass or quartz filler and can be made to match the color of your tooth. Composite fillings are also fairly durable and are ideal for small-to-mid-size restorations in areas of your mouth that perform moderate chewing.
  • Metals: Gold or silver amalgam are the most common metal used for cavity filling. Gold fillings can cost as much as 10 times more than silver amalgam fillings, but some people prefer the appearance of gold to silver fillings if they want the durability of metal vs. a less-durable composite material. Some people don’t like the appearance of metal fillings, but metal fillings can last as long as 10-15 years before they need to be replaced.
  • Ceramic: A ceramic cavity filling (usually made of porcelain) is tooth-colored, and it may be less likely to show tooth stains over time than a composite cavity filling. But the price is a factor—a ceramic filling can be nearly as expensive as a gold cavity filling.
  • Glass Ionomer: This blend of acrylic and glass is used to create a cavity filling that releases fluoride to help protect teeth. But a glass ionomer cavity filling is less durable than other types and may need to be replaced in as little as five years.

Taking Care of Cavity Fillings


You may experience some sensitivity and pain after receiving tooth fillings, but this discomfort should subside. Don't neglect your oral care routine. Instead, try products designed specifically to protect sensitive teeth. 

When to Replace a Cavity Filling


Tooth fillings usually last for many years before they need to be replaced. But tooth fillings can wear out over years of chewing. If you clench or grind your teeth, you may need to have tooth fillings replaced sooner.

If you notice signs of wear on your tooth fillings, such as cracks or worn areas, see your dentist to have the filling replaced as soon as possible. Continuing to chew with a damaged filling can cause the tooth to crack and require additional repair that is more expensive and more complicated than a simple cavity filling. If additional tooth decay develops around a filling, whether or not the filling is damaged, your dentist may choose to repair the tooth with a crown instead of a second cavity filling.

Other Potential Problems with Cavity Fillings


It’s important to know about potential problems, so you can see your dentist promptly to have cavity fillings adjusted or repaired. Possible complications from cavity fillings include:
  • Infection: Sometimes a cavity filling will pull away from the tooth to which it is attached, creating a small space. This space can be a breeding ground for bacteria that can cause additional tooth decay. If you notice a space between your tooth and your cavity filling, visit a dentist as soon as possible.
  • Damage: Sometimes a cavity filling breaks, cracks, or falls out. Damage to a filling can occur when you bite down on something hard or if you are hit in the mouth while playing sports. See a dentist as soon as you notice damage to a cavity filling to avoid irritation and infection of the unprotected tooth.
