There are two types of halitosis or bad breath, which can vary depending on the cause. In the following sections, we will define each type and highlight their differences.
Certain foods and drinks can contribute to bad breath due to their strong odors or their effects on the mouth. Foods like garlic, onions, and spices contain volatile compounds that are absorbed into the bloodstream and exhaled through the lungs. Coffee and alcohol can leave a lingering odor in the mouth due to their strong flavors.

Many don’t know how their diet can be one of the causes of bad breath. Eating a high-protein, low-carb diet can cause your metabolism to change because protein is harder for your body to digest. They tend to release sulfurous gases when they don’t metabolize. To avoid this, eat a more balanced and nutritious diet full of vegetables and herbs.
Tonsil stones are risk-free buildup that will go away on their own. However, the duration of tonsil stones can vary from person to person. They may go away or melt on their own in a short period, or they can also stay for weeks if they are deep in the throat and bacteria continue to grow on them. Besides, if proper oral hygiene is not performed, it may last for years and lead to a more serious problem, such as tonsillitis.
