Khaberni - Most people suffer from bad breath when waking up, which may be harmless and completely natural. However, it can sometimes be a sign of underlying health problems.
In a report for "Surya Life," dentist Dr. Mohammad Ali explained that persistent or unusually strong bad breath can sometimes indicate an underlying health issue.
He added, "Bad breath in the morning is very common due to decreased saliva flow during sleep. Saliva is more than just moisture; it dilutes acidity and carries antimicrobial proteins such as lactoferrin, lysozyme, and secretory immunoglobulins, which help fight bacteria and remove food particles. When this natural protection diminishes at night, bacteria can accumulate and multiply."
Bigger health issues
Gum disease is one of the most common and significant causes of persistent morning bad breath.
The bacteria associated with sulfur gases produced inside the mouth during sleep, due to food residues, result in inflammation and damage to the tissues supporting the teeth.
Since early gum disease may progress with few obvious symptoms, persistent bad breath can be an early warning sign.
Dry mouth
If you constantly suffer from dry mouth, this may intensify morning bad breath.
Saliva not only helps moisturize the mouth, but also provides protective agents that limit harmful bacteria and reduce acidity.
Many common medications, including blood pressure drugs, antidepressants, and antihistamines, reduce saliva flow.
With reduced protection, bacteria thrive, sulfur compounds build up, and the foul smell may persist even after brushing your teeth.
Sinus and throat infections
Persistent bad breath may occur due to an upper respiratory tract infection.
Postnasal drip resulting from sinusitis may cover the back of the throat and tongue with mucus, which bacteria turn into foul-smelling gases.
Chronic tonsillitis can have a similar effect, especially when there are stones in the tonsils, which may exacerbate the problem.
These calcified deposits can release concentrated sulfur compounds that mouthwash may not completely remove, because their source lies deep in the throat.
Esophageal reflux
Esophageal reflux is another potential cause. At night, stomach acid and partially digested food can move back into the esophagus, and sometimes into the mouth.
Systemic diseases
Sometimes, morning bad breath may indicate an underlying disease, such as diabetes, or kidney and liver diseases.
Prevention methods
Brush your teeth and tongue with a toothbrush and floss.
Maintain body hydration.
Use an alcohol-free, antimicrobial mouthwash.
Pay attention to your diet, especially garlic and onions.
Avoid late-night snacks.
Consult a dentist or doctor if morning bad breath persists.
