Maintaining fresh breath and good oral health goes beyond brushing and flossing. Recent research highlights the benefits of oral probiotics in balancing the mouth’s microbiome health and combating bad breath. In this article, we explore how oral probiotics work and why they are an effective solution for halitosis.
What Are Oral Probiotics?
Oral probiotics are beneficial bacteria that support a healthy oral environment. Unlike probiotics that aid digestion, these strains specifically target the bacteria in the mouth. By promoting microbiome health, they help prevent the overgrowth of harmful bacteria that contribute to bad breath and other dental issues.
How Oral Probiotics Combat Bad Breath
1. Restoring Microbial Balance
An imbalance in oral bacteria can lead to unpleasant odours. Oral probiotics introduce beneficial bacteria that compete with odour-causing microbes, restoring a healthy balance.
2. Reducing Volatile Sulphur Compounds (VSCs)
Harmful bacteria in the mouth break down proteins and release VSCs, which cause bad breath. Certain oral probiotics neutralise these compounds, leading to fresher breath.
3. Preventing Plaque and Gum Disease
By enhancing microbiome health, oral probiotics reduce the accumulation of plaque and the risk of gum disease, both of which contribute to bad breath.
4. Promoting Saliva Production
Dry mouth fosters bacterial growth and worsens bad breath. Some oral probiotics stimulate saliva production, keeping the mouth hydrated and reducing odours.
How to Incorporate Oral Probiotics into Your Routine
1. Probiotic Lozenges or Chewing Gums
Products infused with oral probiotics provide direct exposure to beneficial bacteria, improving microbiome health.
2. Probiotic Mouthwash
Unlike traditional mouthwashes that kill all bacteria, probiotic mouthwashes selectively promote good bacteria while reducing odour-causing microbes.
3. Fermented Foods and Supplements
Yogurt, kefir, and probiotic supplements contain strains that can benefit oral and gut health simultaneously.
Benefits of Oral Probiotics Beyond Fresh Breath
- Improved Gum Health: Reduces inflammation and supports stronger gums.
- Lower Risk of Cavities: Inhibits cavity-causing bacteria.
- Enhanced Overall Microbiome Health: Contributes to better digestion and immune function.
Oral probiotics offer a natural and effective way to combat bad breath while improving microbiome health. By incorporating them into your daily routine, you can enjoy fresher breath and better oral hygiene. Speak with your dentist about the best oral probiotics for your needs.
