Bad Breath? These 8 Hidden Causes Might Surprise You!

Dry Mouth – Saliva helps wash away bacteria, and a lack of it can cause a foul odor. Dehydration or certain medications can lead to dry mouth. 

Tonsil Stones – These small, calcified bits of debris get trapped in your tonsils and emit a bad smell. 

Acid Reflux – GERD and acid reflux can push stomach acids into the throat, causing a sour or unpleasant odor. 

High-Protein Diets – Diets rich in protein can lead to ketosis, which causes a distinct breath odor. 

Sinus Infections – Mucus buildup from allergies or infections can lead to bacteria growth, resulting in bad breath. 

Unclean Tongue – Bacteria and food particles stick to the tongue, leading to persistent bad breath. 

Certain Medications – Some medicines cause dry mouth or chemical changes that affect breath odor. 

Hidden Dental Issues – Cavities, gum disease, or old dental work can harbor bacteria that produce a bad smell.
