The oral view at the first visit is shown in Figure 1. Extensive tooth wear was seen in many teeth both on occlusal and cervical surfaces (Figure 1).

An X-ray of the tooth did not exhibit any periapical lesion, but the root canals seemed poorly treated (Figure 2(a)); so we removed the metal crown and started endodontic treatment. Large amounts of pus accompanied by malodor came from the root canals, but the root canals had improved at the second visit and were filled at the third visit (Figure 2(b)).

We then filled or coated the already lost enamel of the teeth (Figure 3).

Several months later, the patient's breath odor was reduced to the physiological level (Figure 4), and neither he nor his family members had any complaints thereafter about his oral malodor.
