Bad breath, medically known as halitosis, is a common problem that can affect anyone at any age. It can cause embarrassment, reduce confidence, and negatively affect social interactions. The good news is that mouth odour is treatable and preventable once you understand its causes and apply the right solutions.

In this article, we’ll explain what causes bad breath, how to get rid of mouth odour naturally and medically, and simple habits to keep your breath fresh all day.

What Causes Mouth Odour or Bad Breath?

Bad breath usually starts in the mouth, but it can also be linked to underlying health conditions. Common causes include:

1. Poor Oral Hygiene

Not brushing and flossing properly allows food particles to remain in the mouth, leading to bacterial growth and unpleasant odours.

2. Tongue Bacteria

The tongue can trap bacteria, dead cells, and food debris, producing sulphur compounds responsible for bad breath.

3. Dry Mouth (Xerostomia)

Saliva helps clean the mouth. When saliva production is low—especially during sleep or due to dehydration—bad breath becomes more noticeable.

4. Certain Foods and Drinks

Garlic, onions, alcohol, and spicy foods can cause lingering mouth odour long after consumption.

5. Smoking and Tobacco Use

Smoking dries the mouth and leaves a persistent foul smell, while also increasing the risk of gum disease.

6. Dental Problems

Cavities, gum disease, tooth infections, and poorly fitted dental appliances can all contribute to bad breath.

7. Medical Conditions

Conditions such as sinus infections, tonsil stones, acid reflux (GERD), diabetes, and liver or kidney disease can cause chronic halitosis.

How to Get Rid of Mouth Odour or Bad Breath

1. Brush Your Teeth Properly

Brush at least twice daily using fluoride toothpaste. Ensure you clean all tooth surfaces for at least two minutes.

2. Clean Your Tongue

Use a tongue scraper or soft toothbrush to gently remove bacteria from the tongue surface.

3. Floss Daily

Flossing removes trapped food particles between teeth that brushing alone cannot reach.

4. Stay Hydrated

Drink plenty of water throughout the day to prevent dry mouth and flush away bacteria.

5. Use Mouthwash

Choose an antibacterial or alcohol-free mouthwash to kill odour-causing bacteria and freshen breath.

6. Chew Sugar-Free Gum

Sugar-free gum stimulates saliva production, which helps clean the mouth naturally.

7. Avoid Smoking and Excess Alcohol

Quitting smoking and limiting alcohol can significantly improve breath quality and overall oral health.
