An amalgam filling is a type of dental filling used to repair a cavity caused by tooth decay. It's made up of a mixture of metals, including silver, tin, copper, and mercury. The term "amalgam" refers to the process of mixing different metals to form a stable and durable material.
Amalgam fillings have been used for over 150 years and are still commonly used today due to their durability, strength, and affordability. The mercury in amalgam fillings has caused some concern over the years, as there is a risk of mercury toxicity if large amounts are ingested. However, the amount of mercury in a single amalgam filling is generally considered safe and well within the limits set by various regulatory agencies.
The use of amalgam fillings is slowly declining in favour of newer materials such as composite resin fillings, which are tooth-coloured and blend in with the surrounding tooth structure. However, amalgam fillings are still considered a reliable and effective treatment option for many patients. Your dentist can help you determine the best type of filling material for your specific needs.
The process of getting an amalgam filling typically involves numbing the area around the affected tooth with a local anaesthetic. The dentist then removes the decayed portion of the tooth using a drill or other dental tool. Once the decay is removed, the dentist cleans the area and prepares it for the filling material.
The amalgam filling material is mixed in a small container and then placed into the prepared tooth cavity. The material is packed tightly into the cavity to ensure that it fills the space completely. The dentist will then shape and polish the filling material so that it fits comfortably with the surrounding teeth and feels natural in the mouth.
After the filling is placed, it's important to avoid eating or drinking for a short time to allow the filling material to harden and set properly. Dr. Mercedes Del Valle in Eugene will provide instructions on how to care for the filling after the procedure, including proper oral hygiene and avoiding hard or sticky foods for a period of time.
Amalgam fillings can last for many years with proper care and maintenance. Regular dental checkups are important to ensure that the filling is still in good condition and to identify any potential issues early on. If the filling does become damaged or worn over time, it may need to be replaced to prevent further decay or damage to the tooth.
