Oral dysgeusia is relatively common, and may be caused by a number of factors. Zinc is a trace element that is critical for many enzymatic activities inside the body. Zinc deficiency is one of the causes of oral dysgeusia. The purpose of this study was to report three cases of oral dysgeusia. Haematological investigation revealed reduction in serum zinc level in all patients. They were prescribed with zinc supplement. Symptoms improved after a month of oral zinc supplementation. Zinc supplement appears to restore oral disturbance due to zinc deficiency and idiopathic taste disorders. However, we still cannot rule the placebo effect.
