Ignoring your dental health can lead to tooth or gum infections like gingivitis or periodontitis. A more severe condition called acute necrotizing ulcerative gingivitis can happen suddenly. Along with other symptoms, these issues can trigger bad breath and a metallic taste in your mouth.
Your senses of smell and taste are closely linked. So any issues with your sinuses might affect your taste buds. Once you’ve kicked the infection clogging your sinuses, your mouth should go back to normal.
