Key Points at a Glance:
- The buildup of bacteria causes bad breath
- Sage can help combat bad breath and also has antiseptic properties
- Watch out for gum and candy
Bad breath is usually caused by the buildup of bacteria that produce an unpleasant odor. Possible causes include: inadequate oral hygiene, certain diets, stress, or dehydration. Tobacco use or a dry mouth can also lead to bad breath. Bacteria can build up in the mouth, especially when food particles have not been adequately removed. However, illnesses or the use of certain medications can also cause bad breath.
Bad breath is not an uncommon phenomenon
Bad breath is common, and practically everyone has experienced it at some point—whether in the morning upon waking or after eating certain foods. Below, we’d like to share what we consider to be the most important tips for combating bad breath:
- Clean your tongue regularly, because most bacteria live on the tongue.
- Mouthwashes with antibacterial properties can help freshen your breath.
- Sage is a tried-and-true home remedy for bad breath and also has disinfectant properties.
- Brush your teeth daily and floss. This helps eliminate odor-causing bacteria.
- Anise and fennel seeds help eliminate bad breath.
- If bad breath is caused by a dry mouth, lemon juice is recommended. The acid stimulates the salivary glands and helps keep your breath fresh.
- Get your teeth cleaned regularly; this will remove plaque from areas that are very difficult to reach on your own.
It is especially important to note that various types of chewing gum and candies (e.g., peppermints) do not actually help with bad breath. Since most of these products contain a high proportion of sugary ingredients—which in turn can promote bacterial growth—they usually have the opposite effect, and the bad breath persists or even gets worse.
When Should You See a Doctor?
In most cases, bad breath has a harmless cause; however, if it persists despite thorough cleaning and oral care, you should contact your family doctor or dentist. Bad breath can also be caused by medical conditions, which must then be properly diagnosed. Above all, it’s important to note that in most cases, no one is to blame for bad breath.
