Choosing the right material for tooth filling is not only limited to beauty, but also plays an important role in the durability of the restoration, oral health and prevention of future treatment costs. Amalgam, or the black material, despite its long history, is still considered one of the most resistant options for restoring back teeth and can withstand strong chewing pressure.

However, many patients have questions about the safety of amalgam and how it differs from white materials. Investigating this issue and choosing the best treatment method requires a detailed examination by the best dentist for tooth restoration in Mashhad in order to choose the most suitable material according to the condition of the tooth.

Inspection of white materials for tooth restoration (composite and ceramic materials)

White materials include resin composites and ceramic restorations that match the color of natural teeth. These materials are very suitable for front teeth and visible areas and create a natural smile. Composites are shaped directly in the office, while ceramics are made in a lab and then bonded to the tooth. These materials require less cutting and adhere to the tooth structure, but are more sensitive to pressure.

Advantages and disadvantages of filling teeth with white material

The most important advantage of white materials is high beauty and perfect harmony with tooth color. These materials also have good adhesion to tooth enamel and more tooth structure is preserved. However, composites are less resistant to pressure than amalgam and wear more quickly in posterior teeth. Higher cost, sensitivity to moisture during installation and possibility of color change over time are other disadvantages of these materials.

Tooth filling with black material or amalgam

Amalgam is one of the oldest and most resistant tooth filling materials, which is made from a combination of silver, tin, copper and a controlled amount of mercury. This material has been used in back teeth for many years due to its high strength and high pressure tolerance. Amalgam is a good choice for patients who value durability and lower cost. Its dark color has made it more known as black material, but in terms of performance, it is still one of the most durable options.

Using black material to fill back teeth

Rear teeth bear the most chewing pressure and need a material with high strength. Amalgam is an ideal option for these areas due to its high resistance to pressure and wear. This material also performs well in wet environment and shows less sensitivity than composite. For this reason, many dentists still recommend the use of amalgam for molar teeth that are not exposed.

Advantages and disadvantages of filling teeth with black material

Among the advantages of amalgam, we can mention long life, reasonable price, resistance to pressure and ease of use. This material is very effective for back teeth. On the other hand, the dark color, the need for more tooth grinding, and the concern of some patients about the presence of mercury are among its disadvantages. Of course, reliable research has shown that amalgam is safe for most patients if used correctly.

Comparison of durability of dental amalgam and composite

In terms of durability, amalgam usually lasts longer than white materials, and in back teeth, it may stay intact for more than ten years. White materials can also last for several years if properly cared for, but are more sensitive to pressure and wear. The choice between the two depends on the location of the tooth, budget, aesthetic preference and the opinion of the dentist. The best option is a choice that is in harmony with the patient's oral conditions and needs.

Final word

Although amalgam has a very good performance in terms of strength and longevity, it creates limitations in terms of aesthetics and the need for more tooth grinding. The choice between black and white materials should be made considering the location of the tooth, the amount of pressure, budget and dentist's opinion. Knowing the advantages and disadvantages of each method will help you make a confident decision and maintain the health of your teeth in the long term.
