It is extremely difficult to clean the cervical portion 6 on the adjacent surface on the defect side, and the cervical portion 6 becomes a non-cleanable area, and plaque, that is, dental plaque, tends to stay and becomes a frequent occurrence site of caries. ing.

[0005] In addition, a local denture used as a defective part prosthesis always requires hooks with clasps necessary for maintaining the denture. A gap is created between the denture and the hook teeth to put the clasp on the hook teeth. As a result, food residue and dental plaque tend to stay in the cervical region 6 of the adjacent teeth 2 and 3 of the defect site 1 and cause damage to important hook teeth.

In order to clean the tooth neck 6, it is conceivable to apply dental floss or an interdental brush.

[0007] However, the use of dental floss is limited to the interdental portions where the interdental brush cannot be inserted, as seen in young people, etc., and the interdental portions as shown in FIG. 10 are large. For cleaning the cervical part 6 in this case, the interdental brush is more optimal because of its higher plaque removing effect.
