If you have cavities or a weakened or fractured tooth, your regular or emergency dentist will likely recommend a filling or a crown. Sometimes these treatments can be used interchangeably, but it’s often better to use one over the other. Dentistry relies on several factors to help determine which option to recommend to patients. It’s important, though, to first understand the difference between crowns and fillings. A crown is a prosthetic device cemented onto the tooth, providing coverage, and strength to a tooth. A filling is a material bonded into a tooth, replacing the damaged tooth structure. Here are some of the ways that a dentist thinks about whether to recommend a filling versus a crown.

How Tooth Decay Causes Cavities
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. Cavities are more common among children, but changes that occur with aging make cavities an adult problem, too. Recession of the gums away from the teeth, combined with an increased incidence of gum disease, can expose tooth roots to plaque. Tooth roots are covered with cementum, …
What is a Composite Filling?
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 …
Cavities
Cavities are permanently damaged areas in the hard surface of your teeth that develop into tiny openings or holes. Cavities, also called tooth decay or caries, are caused by a combination of factors, including bacteria in your mouth, frequent snacking, sipping sugary drinks and not cleaning your teeth well. Cavities and tooth decay are among the world's most common health problems. They're especially common in children, teenagers and older adults. But anyone who has teeth can get cavities, including infants. If cavities aren't treated, they get larger and affect deeper layers of your teeth. They can lead to a severe toothache, infection and tooth loss. Regular dental visits and good brushing and flossing habits are your best …
