Bad breath can be embarrassing and affect your self-confidence. If you're looking for a simple solution right away: brush your teeth thoroughly, clean your tongue, floss, drink a glass of water, and chew sugar-free gum. Most people notice improvement after taking these steps. If the problem persists for more than two weeks, it's best to schedule an appointment  at the dentist because sometimes professional treatment is needed.

What is bad breath (halitosis)?

Bad breath, medically known as halitosis, means that your mouth has an unpleasant odor that others can smell. Sometimes the odor is intermittent, such as after eating garlic or onions. But if it is persistent or comes back often, it is a sign that you need to look for the cause. It most often comes from the mouth itself, but sometimes it also indicates problems with the sinuses, throat, stomach or other parts of the body. It is important to distinguish between temporary odor and permanent halitosis, as the treatments are different.

Quick solution – what to do now

When you suddenly develop bad breath, the first steps are practical and simple. Brush your teeth, but don’t just brush your teeth – pay attention to the back teeth and the gum line. Cleaning your tongue is often neglected, and that’s where the bacteria and white plaque that contribute most to bad breath accumulate. Flossing removes food particles between your teeth where your toothbrush can’t reach. Drinking water and chewing sugar-free gum stimulate saliva production, which naturally washes away bacteria. These measures often provide immediate relief, but if the bad breath returns, you should look for a deeper cause.

Main causes of bad breath

Causes from the oral cavity

The most common cause of halitosis lies in the oral cavity itself. A layer (biofilm) can form on the back of the tongue, where bacteria accumulate. They break down proteins and produce volatile sulfur compounds – these compounds have a characteristic unpleasant odor. Cavities, faulty fillings and limescale deposits under the gums also contribute to the problem. If you have gingivitis or deeper periodontal pockets, bacteria hide in these places and bad breath becomes persistent. In these cases, home hygiene alone is often not enough – professional intervention is required.

Causes from the nose and throat

Sometimes the odor originates in the upper respiratory tract. Chronic sinusitis, sinus drainage that drains down the back of the throat, or tonsillitis (inflamed tonsils) can cause bad breath. People who have a persistent runny nose or frequent sore throats often also notice bad breath. In such situations, an examination by an ENT specialist can help identify and treat the source of the problem.

Gastrointestinal and systemic causes

Although less common, bad breath can start in the digestive system. Acid reflux (GERD) can cause sour or foul-smelling breath. Even more rarely, metabolic disorders such as diabetic ketoacidosis can produce a characteristic breath odor that requires immediate medical attention. If you also have symptoms such as frequent heartburn, abdominal pain, or significant weight loss, it is important to seek medical advice.

Medications and dry mouth

Many medications reduce saliva production. Saliva is important because it mechanically washes away food debris and contains protective factors. When the mouth is dry (a condition called xerostomia), bacteria multiply more easily and the smell worsens. Mouth breathing, dehydration and smoking further worsen the condition. Sometimes it is enough to increase fluid intake or change medication, but this should always be done under the advice of a doctor.

How to diagnose bad breath

Diagnosis begins with an interview and examination. The dentist will ask you when the bad breath was noticed, how often it occurs, and in what situations it gets worse. The examination includes the teeth, gums, and tongue. The doctor may probe the pockets around the teeth to check for periodontal disease. If an extraoral source is suspected, additional tests or referral to an ENT or gastroenterologist will be necessary. In rare cases, instruments that measure the concentration of volatile sulfur compounds are used, but most often a well-conducted clinical assessment is sufficient.

Natural treatment and home remedies (bad breath natural treatment)

There are a few simple habits you can start right away that often work well. First, cleaning your tongue every morning and after meals greatly reduces the plaque that feeds bacteria. Second, regular oral hygiene—brushing your teeth twice a day and flossing daily—prevents the buildup of food and plaque. Third, hydration and saliva stimulation are important; chewing sugar-free gum helps your body naturally rinse your mouth. Parsley tea or freshly chewed parsley can temporarily freshen your breath, while green tea has mild antibacterial properties and helps reduce odor for a short time. Probiotics that target the oral microbiota are being studied and may help in certain cases, but they are not a substitute for dental checkups and treatment.

Professional treatment

If home remedies do not work, your dentist can offer specific interventions. Professional cleaning and scaling remove bacterial loads that cannot be removed by brushing alone. Treating periodontal disease may require deep cleaning of the pockets, topical or systemic therapies. Repairing damaged fillings and resolving cavities close off the areas where food accumulates. If tonsillitis, sinusitis or reflux is suspected, collaboration with the appropriate specialists will be necessary. Only addressing the underlying cause usually leads to lasting improvement.

When to see a dentist or doctor

Seek professional help if bad breath persists for more than two weeks despite regular oral hygiene. Also, see a doctor immediately if bad breath occurs along with bleeding gums, pain, swelling, difficulty swallowing, or weight loss. Early diagnosis helps identify the problem and prevent the progression of the disease, which may require more extensive surgery.

Prevention – how to keep your breath fresh every day

The best prevention is consistent and simple. Brush your teeth twice a day, clean your tongue every day, and floss. Regular dental checkups and professional cleanings at least once a year can help detect and treat problems before they become a permanent source of bad breath. Staying well hydrated and avoiding smoking also go a long way toward freshening your breath. If you wear dentures, take care of them and clean them regularly to prevent bacteria from building up underneath them.

Conclusion

Bad breath is unpleasant, but in most cases it can be treated. The most common cause lies in the oral cavity and can be significantly reduced with good habits: brushing your teeth, cleaning your tongue, flossing and sufficient hydration. If basic measures do not help or if you have additional symptoms, contact your dentist or doctor. At Mondent, we perform all examinations and treatments that address the causes of bad breath.
