Bad breath (halitosis) may be temporarily masked by eating garlic, which can alter oral odor and exert antibacterial effects. However, it is important to investigate whether gastrointestinal disorders are present. For instance, patients with gastritis should avoid consuming raw garlic, as it may irritate the gastric mucosa and cause discomfort. Individuals with halitosis should consult a dentist or oral medicine specialist; attention should also be paid to whether inflammatory oral conditions are present.
