It is difficult to say what material is the best for filling teeth, only that it is the most suitable or more suitable, and what material to use needs to be decided according to the situation. Commonly used filling materials include the following:

1, photosensitive curing resin: At present, photosensitive curing resin is usually used for tooth filling, which belongs to resin material and is soft in texture, and will harden after being filled with light. Photosensitive curing resin has many colors, because people's teeth are different in color, which may be white or yellow. Photosensitive curing resin materials also adapt to the color of human teeth, and there are different color numbers to choose from. Photosensitive curing resins are also divided into manufacturers and brands. Some resins have better colors, better refraction, transmission and reflection of light, or higher hardness and are easier to polish. Other materials are similar to chameleon, which can adapt to the color of teeth with fillings and will automatically change to adapt to the color of teeth;

2, bonding: the bonding force is stronger, it is not easy to fall off after filling teeth, and it is more convenient to use;

3. Amalgam: Amalgam has been used to fill teeth in the past, and the operation is simple. Amalgam is also durable when the retention and resistance of the hole are sufficient. But amalgam will pollute the environment, and the color is not good-looking and not sticky. It needs to prepare a certain retention form for teeth, so it is rarely used now.

3. Mosaic: There are metal materials, such as precious metal mosaic, and ceramic mosaic, such as all-ceramic mosaic. If you use inlay to fill teeth, the general effect is better, especially to restore the contact point inside and restore the shape of teeth, with higher strength and better color, but the disadvantage is that it is more expensive.
