Dental Fillings in Los Angeles

Tooth decay is the destruction of your tooth enamel, the hard, outer layer of your teeth. It can be a problem for children, teens and adults. Plaque, a sticky film of bacteria, constantly forms on your teeth. When you eat or drink foods containing sugars, the bacteria in plaque produce acids that attack tooth enamel. The stickiness of the plaque keeps these acids in contact with your teeth and over time the enamel can break down. This is when cavities can form. A cavity is a little hole in your tooth. Unless the hole is too large, the natural look and functionality of the tooth can be saved by filling the cavity with metal or composite material.

Composite Dental Fillings

Composite resins, or tooth-colored fillings, provide good durability and resistance to fracture in small- to mid-size fillings that need to withstand moderate pressure from the constant stress of chewing. They can be used on either front or back teeth. They are a good choice for people who prefer that their fillings look more natural. Composites cost more than amalgam and occasionally are not covered by some insurance plans. Also, no dental filling lasts forever. Some studies show that composite fillings can be less durable and need to be replaced more often than amalgam fillings.

It generally takes longer to place a composite filling than it does for a metal filling. That’s because composite fillings require the tooth be kept clean and dry while the cavity is being filled. Tooth-colored fillings are now used more often than amalgam or gold fillings, probably due to cosmetics. In a society focused on a white, bright smile, people tend to want fillings that blend with the natural color of their teeth.

Metal Dental Fillings

Metal fillings, silver amalgam or gold, are usually very durable and relatively easy to make, however these types of fillings are not natural looking, especially when the filling is near the front of the mouth, where it may show when you laugh or speak. Also, to prepare the tooth, the dentist may need to remove more tooth structure to place an amalgam filling than for other types of fillings.

Silver Amalgam Fillings

Dental amalgam is made from a combination of metals that include mercury, silver, tin, and copper. Sometimes described as “silver-colored” fillings, dental amalgam has been used by dentists for more than 100 years because it lasts a long time and is less expensive than other cavity-filling materials such as tooth-colored composites or gold fillings.

Because of their durability, these silver-colored fillings are often the best choice for large cavities or those that occur in the back teeth where a lot of force is needed to chew. Amalgam hardens quickly so it is useful in areas that are difficult to keep dry during placement, such as below the gum line. Because it takes less time to place than tooth-colored fillings, amalgam is also an effective material for children and special needs people who may have a difficult time staying still during treatment.

Gold Fillings

Gold fillings, also called inlays or onlays, are composed of an alloy of gold, copper and other metals. This type of dental filling is usually considered the most durable, lasting 20 years or more, but it is also the most costly. Gold fillings also require more than one office visit to place because they require impressions to manufacture at a dental laboratory.

Direct placement of gold is a restoration called a gold foil. These types of dental restorations are infrequently performed and are usually used for small fillings. Gold foils can be placed in one visit, just like an amalgam or composite filling.

Ultimately, the best dental filling is no dental filling. Prevention is the best medicine. You can dramatically decrease your risk of cavities and other dental diseases simply by brushing your teeth twice a day with fluoride toothpaste, flossing daily, eating a balanced diet, and visiting your favorite LA dentist River Dentistry regularly.
