If you simply repair cavities, the color of composite resin will be more realistic. The imported one will cost more than 100 yuan, and the domestic one will cost tens of yuan. You can also get amalgam fillings for your back teeth, but they are metallic and have poor aesthetics and cost less than fifty yuan. Generally, one treatment is sufficient, but for deep caries that require soothing, two treatments may be required. To fill a tooth, you need to remove the decay first and prepare it into a certain hole shape. Generally, the tooth needs to be drilled, and resin filling requires less drilling. If the tooth has pulpitis or apical periodontitis, root canal treatment must be performed first and then repaired. It will cost an extra 100 to 300 yuan, depending on the number of root canals of the tooth. It lasts three to four times. , it takes more than half a month to complete the treatment.
