Composite Fillings in St George

The most common disease in the United States is a bacterial infection of the teeth. More widely known as cavities or caries, bacteria-infected teeth turn into a dense mushy byproduct. Because of this statistic, the most common dental procedure done in the United States is the filling. 

Many different materials have been used for dental fillings. Prior to the use of composite fillings, most fillings were made of a combination of metals, called amalgam. Metal amalgam fillings are also called silver fillings or mercury fillings. They have been used for decades and have the benefit of being very robust. Metal fillings also seal the filling area through oxidation. However, in recent years people have become concerned with metal fillings leaching metal into the body. Amalgam fillings have additionally been rejected because they turn darker over time, even graying the tooth. No matter their shortcomings, there is little doubt that amalgam fillings have been of great service to the general population for decades. 

The most common filling material now is composite. A composite (tooth-colored) filling is used to repair a tooth that is affected by decay, cracks, fractures, etc.  The decayed or affected portion of the tooth is removed and then filled with a composite filling. Because composite fillings are tooth colored, they can be closely matched to the color of existing teeth, and are more aesthetically suited for use in front teeth or more visible areas of the mouth. They are very durable and will last many years, giving you a long-lasting, beautiful smile.

Reasons for composite fillings:

• Decayed teeth.
• Closing space between two teeth.
• Cracked or broken teeth.
• Chipped teeth.
• Worn teeth.

Composite fillings are placed in one appointment.  While the tooth is numb, Dr. Bergman removes the decay.  The space is then thoroughly cleaned.  If the decay was near the nerve of the tooth, a special medication is applied for added protection.  Soap is used to remove protein tags from the preparation surface and then a bonding agent is scrubbed into the space. The composite filling is then precisely placed, shaped, and polished, restoring your tooth to its original shape and function. 

Sometimes, sensitivity to hot and cold occurs when composite fillings are first placed; however, this will subside shortly after your tooth acclimates to the new filling. Good oral hygiene practices, eating habits, and regular dental visits will aid in the life of your new fillings.
