Bad breath and a sweet taste in the mouth may be caused by oral diseases such as gingivitis or apical periodontitis, or could result from digestive system disorders such as gastric ulcers. Additionally, individuals with diabetes may also experience bad breath and a sweet taste in the mouth. When these symptoms occur, it is recommended to seek timely evaluation at a正规三级甲等 hospital, undergo relevant examinations, and obtain a clear diagnosis.
