The reason why I have bad breath even after brushing my teeth was because of this

bacterial reproduction of the tongue
The most common cause of bad breath is bacteria that build up on the tongue. Since brushing teeth mainly only wipes out the surface of the teeth, bacteria and food debris left behind on the back of the tongue remain intact. Sulfur compounds generated here are the main culprits of the strong odor. Using a tongue cleaner after waking up in the morning or making a habit of brushing your tongue carefully while brushing your teeth can help relieve bad breath.
Dry mouth and lack of saliva
Lack of saliva is a common cause of bad breath. Saliva plays an important role in cleaning bacteria in the oral cavity and controlling acidity. However, caffeine, alcohol, smoking, and stress inhibit saliva secretion, making the mouth dry easily. When the mouth is dry, bacteria reproduce quickly, resulting in a unique bad breath. It is also necessary to drink enough water a day and reduce the habit of sleeping with your mouth open when you sleep.
a one-way stone
When food debris and bacteria harden in a small gap in the tonsil, tonsil stones occur. Even small stones should not be easily seen because these stones give off a unique strong smell. In addition, tonsil stones can be accompanied by discomfort or foreign body sensations when swallowing. In severe cases, it is difficult to remove it on its own, so it is recommended to manage it through otolaryngology treatment.
gastrointestinal and systemic diseases
Bad breath is closely related not only to oral problems but also to health in the body. Diseases such as reflux esophagitis, chronic indigestion, liver disease, and diabetes can cause bad breath. In particular, when stomach acid flows backward, odors rise to the throat and mouth, and oral care alone does not improve. In this case, it is necessary to receive internal medical treatment along with improving lifestyle.
In addition, chronic diseases such as diabetes and kidney failure cause bad breath. Diabetes can smell like fruit and kidney failure can smell like ammonia. Let's detect the disease early through regular medical checkups. If you consult a doctor and receive proper treatment, the smell will improve.
nasal and sinus problems
Rhinitis and sinusitis are hidden causes of bad breath. Inflammation or pus in the mucous membrane of the nose creates an odor. Use a nasal wash (saline spray), and if the symptoms are severe, see an ear, nose and throat doctor. Nose health is the key to reducing bad breath.
stress and irregular living
Stress reduces saliva secretion and lowers immunity, making it easy for bacteria in the mouth to reproduce. In addition, lack of sleep and irregular lifestyles also worsen bad breath. Sufficient sleep and regular living can be fundamental precautions.
Bad breath is not just a problem of a lack of brushing teeth, but can be a sign related to lifestyle and health in general. Knowing exactly the cause and improving it can maintain a refreshing oral environment. Don't ignore small inconveniences and check your oral care and lifestyle. Clean breathing is the most important basis for increasing confidence.
