Difference Between Dental Cleaning & Polishing?

The 5 most common types of dental fillings for teeth are:

Amalgam Filling (Silver Filling)

Silver (amalgam) fillings are made of different materials, such as mercury, tin, silver, copper, and zinc. When this filling is placed on the tooth, it has a silver appearance, which for many people, affects the aesthetics of the tooth.

Previously they were widely used. Today, they use dental fillings made of other materials that do not affect the tooth's appearance and look more natural. The silver filling lasts 10 to 15 years and is cheaper than other dental fillings.

In addition, it is stronger and can withstand the force of chewing. One of the disadvantages of the silver dental filling is that it sometimes requires further destruction of the tooth structure to make more space to contain the silver filling.

Gold Filling

Gold fillings are made primarily of gold and may contain a combination of other materials. These fillings are usually 75% gold; the other 25% may contain silver and other minor metals. They are durable fillings, lasting between 10 and 15 years since gold does not corrode, but they tend to be more expensive.

The gold filling can also withstand the forces of chewing and often has a pleasing appearance to the eye.

Gold Dental Restorations

Porcelain Filling

Porcelain or ceramic dental fillings are made of a high-quality ceramic material that can last more than 15 years with proper maintenance. It is not as strong as amalgam and gold fillings but blends perfectly into the tooth.

Such fillings are more stain resistant compared to composite resin material. They are often as expensive as gold fillings and can give your teeth a more natural appearance.

Tooth-Colored Composite Fillings

In the teeth filling process, there are also tooth-colored composite fillings. They are called composite or direct fillings made of tooth-colored adhesive-like material.

This filling is applied directly to the tooth, and the shade can match the color of your natural teeth. In addition to being used as a filling material for cavities, tooth-colored composite fillings are used to repair worn, broken, or chipped teeth.

Currently, this is one of the most common fillings recommended by dentists. It can last 5 years, but it can also come off the tooth more easily, depending on the location of the filling.

Is Dental Implant Painful?

Glass Ionomer

Another types of dental fillings is glass ionomer. It is a filler material made of acrylic and specific glass material. This material is used primarily for fillings below the gum line.

These fillings are weaker than composite resin fillings and can crack or wear away more easily. Glass ionomer fillings release fluoride, which can help protect your teeth from further decay.

They usually last 5 years or less and cost about the same as composite resin fillings.
