How Fillings Work and Why Our Practice Uses Composite Resin Bonding

Tooth-Colored Fillings Portland OR At NW Heights Dental, we see patients on a regular basis who have dental concerns that need to be addressed. This may include cavities that have developed on the teeth. Cavities, or tooth decay, causes permanent damage to the natural tooth enamel and needs to be diagnosed and addressed as soon as possible.

Treatment for cavities

The most popular treatment for cavities is that of dental fillings. Fillings are when the dentist uses a certain material to place into the area of decay after it has been treated and disinfected to seal off the tooth and stop the progression of the condition. Once a tooth is filled, many patients will no longer experience sensitivity and pain that often accompanies a cavity. Additionally, it keeps patients from having further issues with their natural tooth, such as an enlarged cavity that may reach the dental pulp and require additional treatments such as root canal therapy.

What materials are used for treatment?

When fillings are required, our team utilizes composite resin fillings. In the past, many dental offices, including some today, used a material called silver amalgam. This material is comprised of approximately 50% mercury. Mercury is not a safe substance for the human body. As this was determined with continued and consistent studies, many dentists moved forward with the use of composite resin bonding. This is a safer material that is also more aesthetic because it matches the color of the natural tooth enamel. Additionally, it does not expand and contract with temperature changes the same way silver amalgam does, greatly reducing the risk of infection within the tooth due to bacteria entering inside the canals.
