If you have a cavity in one of your teeth, your dentist will most likely advise you to have a filling as soon as possible to prevent infection and strengthen your tooth. Dental restorations are made from various materials, but the most frequent fillings are composite (or composite resin) and amalgam. 

For years, amalgam was the most often utilized material, but composite fillings have grown in favor because they combined appearance and longevity. To know more about composite fillings, how long they last, and how safe they are, speak to a dentist in Northeast Philadelphia today. 

What are composite fillings? 

Composite fillings seem more natural than alternative solutions. The composite material may be adjusted to match the shade of your teeth, making them practically indistinguishable to anybody who looks at your mouth.

But what exactly is that tooth-colored substance? It combines plastic (acrylic) resin and powdered glass filler. It may be used for a wide range of dental restorations, including: 

• inlays
• veneers
• fillings
• crowns

Dentists may also utilize this composite resin material to repair or replace damaged or chipped teeth.

Other filling materials 

When it comes to filling materials, your dentist may provide numerous options. Here is how they compare to one another.

• Amalgam (silver) 

This was the most prevalent form of filling for many years, and it is still widely used in many world regions. They are extremely sturdy and can survive for 15 years or more. 

Furthermore, the procedure is rather uncomplicated because the dentist does not have to worry about keeping the tooth clean and dry throughout the installation. They are also less expensive than other dental restorative materials. 

However, their popularity has dwindled in recent years. They do not seem as natural because they are not tooth-colored.

Amalgam fillings contain mercury, although the American Dental Association considers them a “viable and safe” choice. According to a 2014 review of the research, there is inadequate evidence of any detrimental occurrences, and further study is needed in this area.

• Gold 

Gold fillings are more costly than other materials, but you get what you pay for. They are long-lasting and can last for 20 years or more. They usually need two visits.

• Ceramic 

Ceramic fillings, which contain a form of porcelain, are also rather long-lasting, with a projected lifespan of up to 15 years. However, they are not widely utilized, are costly, and need two visits.

While composite fillings are robust, they have a shorter life duration. According to one 2010 study, a composite resin filling lasts roughly seven years. Speak with an expert dental professional today for more information.
