If you have a cavity, one of the top recommendations from Burnsville, MN dentists is to explore the different filling options. Fillings help stop decay from getting worse and improve your overall dental health.
The two most common types of fillings are silver amalgam and tooth-colored composite, but there are several other options available. Considering the pros and cons of each can help you choose the best filling for your needs.
Silver amalgam is the most popular material because it’s very durable and affordable. However, it is quite noticeable and not ideal if you’re concerned about aesthetics. This type of filling is a mix of silver, tin, mercury, copper, and other metals, with mercury making up over 50%. Dentists often recommend it because it can last over 15 years, much longer than other materials.
On the downside, silver amalgam fillings can be more challenging for dentists to work with because they need to avoid contamination by blood or saliva during the procedure.
Composite fillings are also a popular choice, especially for those who care about appearance. Made from resin or plastic, these materials can be matched to the color of your teeth, making them less noticeable. However, they are more expensive and typically need to be replaced every five years. Dentists use a curing light to harden the resin, but be aware that composite fillings can expand and contract, sometimes causing teeth to crack.
For children, many dentists recommend glass ionomer fillings. These are made from glass and acrylic and release fluoride to help prevent decay. However, they usually last less than five years and may wear down or fracture over time. While they blend in with teeth better than metal fillings, they don’t match as seamlessly as composite resins.
Gold fillings are another durable option, capable of lasting over 15 years without losing quality. However, they are non-corrosive and extremely durable, making them a long-lasting choice. Despite these benefits, it can be hard to find a dentist in Burnsville, MN, who offers gold fillings due to the availability of other alternatives.
