What are the materials for filling teeth?

There are many kinds of materials for filling teeth, including:

1. clove oil zinc oxide: This is a temporary sealing agent, which can relieve pain when the cavity is deep. After 1-2 weeks, the allergic symptoms disappeared and permanent filling materials were used.

2. Calcium hydroxide: It can be used as pulp protection or bedding, which can promote the formation of restorative dentin.

3. Amalgam: This material is the cheapest and most affordable, with high strength, wear resistance, corrosion resistance and long service life. It is a traditional filling material for posterior teeth. But the disadvantages are also obvious: poor aesthetics, mismatch with natural teeth, and great stimulation to dental pulp.

4. Glass ions: This material can slowly release fluoride ions, which has certain caries prevention and health care effects on teeth. However, it has low compressive strength, low hardness and easy wear, and is not suitable for posterior teeth restoration.

5. Composite resin: it can make the material chemically combine with the tooth tissue, so that the affected tooth can be repaired with little or no grinding. In addition, its color is similar to that of teeth, and the restoration is natural and beautiful. The disadvantage is not as strong as amalgam.

6. Nano-resin: Its filler is nano-sized, translucent and milky white. Compared with composite resin, it has better fidelity, more wear resistance and is not easy to fall off, but it is also more expensive. At present, 3M nano resin is popular in the market.

7. Inlay: Strictly speaking, this is a method of tooth restoration. At present, all-ceramic inlay is widely used, which is more beautiful, firm and durable than resin. The disadvantage is that the cost is higher.

Generally speaking, the choice of filling materials needs to be decided according to the specific situation of patients, doctors' suggestions and personal needs. If in doubt or need further information, it is recommended to consult a professional dentist.
