Over time, bacteria and plaque can cause tooth decay. If left untreated, that decay can lead to gum disease, bad breath, and other serious health problems inside and outside your mouth. This occurrence is known as cavities, and your dentist will be able to test for and treat all types of cavities with something called a filling. Different types of dental fillings are also used to repair cracked and broken teeth that may have worn down over the years.
The tooth is first numbed, and then your dentist will drill into the tooth to remove all signs of decay. After which, the cavity that was left open by the caries removal will be filled. There are many different types of dental fillings, appropriate for different situations. There are two types of indirect fills. The first type, inlays, feature dental work within the cusps of the tooth surface. On the other hand, onlays cover more than one cusp, involve much more extensive work, and are often considered partial crowns.
Many practices offer cast gold fillings. While these are expensive, they are very durable and can protect a tooth socket for up to 15 years (sometimes longer). Gold is a very strong metal and can withstand a lot of chewing and other types of wear. Some people also prefer the look of the gold to silver colored metals offered. Keep in mind that these types of fillings are expensive and may require more than one visit to the dentist to properly fill the cavity. Silver is also widely used because it is durable and very strong. On the other hand, silver does not match the natural color of the teeth, and a small percentage of patients experience an allergic reaction to this type of metal.
Today, dentists use composites to fill cavities, mainly because they are available in natural tooth-colored varieties. Composites provide a good bond to the tooth that can support the tooth for long-term use. Composites can also be used to repair cracked or broken teeth, but some dentists feel they lack the durability of other types of dental fillings. They can be chipped with this type, and many cost up to twice as much as other fill alternatives.
Ceramic is widely used by dentists because it is the most stain resistant, natural looking and most durable. Keep in mind that this type of filling can cost as much as gold. You may be offered glass or acrylic if your filling falls below the gum line. This type of filling is also recommended for young children, because it releases fluoride at the gum line which can further strengthen and protect teeth and gums. However, acrylic does not last as long as other options and needs to be replaced or repaired after only five years.
Discuss your options with your dentist before deciding on a filling. Not all filling options may be available at your dentist’s office, and some options may not be right for you. Choose the most practical and natural looking filling for your cavity to maintain a healthy and beautiful smile.
