What material is good for filling teeth and making crowns?
Hello, there are several types of dental crowns. You can choose a crown according to your own situation:

1. Precious metal crown: Also known as golden crown, it has good biocompatibility, stable metal performance, corrosion resistance and good metal ductility, and rarely causes gingival discoloration.

2. Co-Cr alloy crown: Co-Cr alloy crown has good physical properties. Because it does not contain nickel, it has good biocompatibility and the probability of gingival discoloration is also reduced. The price is moderate, so it is a crown suitable for ordinary people.

3. Nickel-chromium alloy crown: the inner crown is made of nickel-chromium alloy, which has poor biocompatibility. Some people have allergic reactions. The slow release of beryllium and nickel will cause gingival discoloration and oral toxicity, which will affect human health.

4. All-ceramic crown: the effect is beautiful and realistic, which is deeply loved by many patients. Strong biocompatibility, no toxic and side effects on the body.
