Think bad breath only comes from skipping your toothbrush? Think again.
Here are some surprising causes of mouth odour you may not have considered:

• Keto Diet: Eating very low-carb triggers the production of ketones, which can cause a distinct mouth odour.
• Medications: Common allergy meds and other prescriptions can reduce saliva flow, encouraging bacterial growth.
• Mouth Breathing: Whether due to habit or nasal issues, breathing through your mouth dries it out—again, less saliva, more bacteria.
• GERD (Acid Reflux): Frequent heartburn and reflux can create a noticeable odour in the mouth.
• Sleep: At night, saliva production naturally drops, which is why you may wake up with ‘morning breath’.
• Poor Sleep Quality: Not getting restful sleep can lead to daytime dryness in the mouth, causing persistent odour.
• Dehydration: Not drinking enough water lets food particles linger, giving bacteria more to feed on.
• Diabetes: High blood sugar and complications like ketoacidosis can both contribute to dry mouth and a fruity-smelling breath.
• Smoking: Tobacco smoke dries the mouth and adds sulphur compounds, increasing the risk of gum disease and bad breath.

So, what can you do about it?

• Brush diligently: Morning and night are a must. After meals is even better. And rinse after strong-smelling foods like onion or garlic.
• Stay hydrated: Water helps flush out food particles and supports saliva production.
• Get your sleep: Quality rest supports better saliva flow and oral health.
• Chew sugar-free gum: A temporary fix, but it can boost saliva flow when needed.
