Bad breath, or halitosis, is a common issue that affects millions of people worldwide. While temporary bad breath can result from certain foods, chronic halitosis is usually caused by bacterial activity in the mouth. Understanding the science behind bad breath and how toothpaste helps can guide you in choosing the right oral care products for fresher breath.

What Causes Bad Breath?

Bad breath occurs when bacteria in the mouth break down food particles, releasing volatile sulphur compounds (VSCs) that produce unpleasant odours. The main contributors to halitosis include:

• Poor oral hygiene – Plaque buildup harbours bacteria that cause bad breath.

• Dry mouth (Xerostomia) – Saliva helps cleanse the mouth; reduced saliva leads to bacterial growth.

• Food particles – Leftover food, especially protein-rich foods, fuels bacterial activity.

• Gum disease – Periodontal infections can lead to persistent bad breath.

• Medical conditions – Issues like acid reflux, diabetes, and respiratory infections can contribute to halitosis.

To combat bad breath, it is essential to reduce bacterial buildup, neutralise odour-causing compounds, and maintain proper saliva flow—this is where toothpaste plays a crucial role.

How Toothpaste Fights Bad Breath

Toothpaste helps freshen breath by incorporating active ingredients that target the root causes of halitosis. The key functions of an effective toothpaste include:

1. Killing Bacteria

• Antibacterial agents such as triclosan, zinc compounds, and stannous fluoride help eliminate bacteria responsible for bad breath.

2. Neutralising Odours

• Ingredients like zinc citrate and chlorine dioxide neutralise volatile sulphur compounds, reducing foul smells.

3. Promoting Saliva Production

• Hydrating agents such as xylitol and glycerin help keep the mouth moist, preventing dry mouth-related bad breath.

4. Removing Plaque and Food Debris

• Abrasive agents like silica and baking soda help remove plaque and food particles that contribute to bad breath.

Choosing the Right Toothpaste for Bad Breath

When selecting a toothpaste to combat halitosis, look for the following active ingredients:

• Lactoperoxidase System – A combination of natural enzymes that help maintain oral balance and fight bad bacteria.

• Lysozyme – An enzyme that breaks down bacterial cell walls, reducing harmful bacteria in the mouth.

• Lactoferrin – A protein that inhibits bacterial growth and supports gum health.

• Glucose Oxidase – Helps generate mild antibacterial effects by producing hydrogen peroxide.

• Xylitol – Reduces bacterial growth and helps prevent dry mouth.

• Fluoride (in certain variants) – Strengthens enamel and prevents cavities.

• Fluoride – Strengthens enamel and fights cavities.

• Drink plenty of water to keep your mouth hydrated.
