The color of resin materials is close to the primary color of teeth, and the effect is very beautiful, so most of them are used in front teeth. Strong adhesion to enamel. Under appropriate circumstances, resin materials can be used to improve the color, shape and size of teeth and beautify smiles. Because of its poor wear resistance, it is mostly used for anterior teeth.

Problems: The procedure of filling teeth with resin material is complicated. Resin materials are not as durable as amalgam because they are easy to wear. The main reason is that when the resin material is solidified, there may be shrinkage, and a small gap will be formed between the resin composite materials, which may cause dentine hypersensitivity to have another chance of tooth decay < P >, and the resin composite materials may also absorb the pigment in food and drink and turn yellow for a long time.

2. Glass ionomer resin

Glass ionomer resin is another tooth color filling material. Usually used in deciduous teeth, near gums and teeth neck. It can cling to the teeth and the fluoride it emits helps to strengthen the teeth and prevent decay. < P > Sensitive cases after filling teeth are also rare.

There are problems: its texture is weaker than composite materials and amalgam, and it is easy to wear. Color is not as beautiful as resin material.

3. Nano and diamond resin

Nano and diamond resin materials are the most advanced high-tech materials for filling teeth, which have the advantages of higher strength and more realistic color.
