What filling materials are used for fillings

Filling materials for dental fillings are mainly amalgam, composite resin, glass ion, etc. 1, amalgam This is a more traditional filling material. The advantage is that it has high compressive strength and wear resistance, can withstand greater chewing pressure, and has a longer use time. The disadvantage is that the color is not beautiful, and the color difference with natural teeth is large, and there may be a potential risk of mercury contamination. 2, composite resin is one of the more widely used materials. Its advantage is that the color is closer to the teeth, good aesthetics, can be adjusted according to the color of the teeth. At the same time, it has a certain adhesion, and tooth tissue can be better combined. However, its strength is slightly lower than that of amalgam, and it may be worn or cracked when it bears a large bite force. 3. Glass ion This material has good adhesive properties and can form chemical bonds with tooth tissues. It can also slowly release fluoride ions to help prevent secondary caries. Glass ion is generally aesthetically pleasing, but it is also used in some parts where the aesthetic requirements are not high. It is also inferior to composite resin and amalgam in strength. When choosing a dental filling material, doctors usually consider the specific conditions of the patient's teeth, such as the location and size of the caries, and the patient's aesthetic requirements, in order to select the most suitable material to achieve a good filling effect. At the same time, patients should also fully communicate with doctors to understand the advantages and disadvantages of various materials in order to make more appropriate choices.
