Another problem plaguing dental clinics is the surging prices of alloys and other materials used in tooth treatment. Their losses in income come at a time when dental clinics are seeking to buy and use the most advanced technologies available to win over new patients. [...] A remaining problem is the cost of treatment. Some phases, such as scanning for mold creation and application of certain fillings, are covered by health insurance. But many others that are not covered are quite pricey. Takabe said that placing a crown on a front tooth costs the patient 140,000 yen to 180,000 yen. The patient also needs to pay 80,000 yen to 140,000 yen for a back tooth filling.
