Top 9 Home Remedies to Combat Bad Breath Naturally

Bad breath, also known as halitosis, can be an embarrassing problem. Fortunately, several simple home remedies may help naturally freshen your breath.

Let’s explore some effective ways to combat bad breath at home:

Good dental hygiene

Maintaining good oral hygiene is the foundation of fresh breath.

• Brush your teeth at least twice a day with fluoride toothpaste, specifically focusing on brushing all surfaces of the teeth and the back of the tongue [2].
• Don’t forget to floss daily to remove food particles and plaque from between your teeth.
• Regularly clean your tongue, as the tongue is a major reservoir for odour-causing bacteria [3], bridges, dentures, retainers, and mouthguards to reduce bacterial buildup.

Use Baking Soda Baking

soda (sodium bicarbonate) is a natural remedy for neutralising odours and maintaining oral hygiene. It may help balance the pH in your mouth, making it less conducive for bacteria to thrive [4].Mix a small amount of baking soda with water to use as a mouthwash, or brush your teeth with it.

Parsley

Parsley contains a high concentration of chlorophyll, which may help temporarily neutralise the odour-causing sulphur compounds in the mouth and has been traditionally used as a breath freshener [5]. Simply chew on fresh parsley leaves to effectively minimise bad breath.

Water

Drinking at least eight glasses of water per day encourages saliva production, which may help wash away bacteria and food particles in the mouth [2]. A dry mouth is a primary contributor to halitosis. Avoid caffeinated and sugary drinks, as they can dry out the mouth, which is a common cause of bad breath.

Yoghurt

Plain, nonfat yoghurt contains probiotics like Lactobacillus that may help combat harmful bacteria in the mouth.Research suggests that daily yoghurt consumption can help reduce bad breath [6]. The probiotics in yoghurt are effective in reducing the severity of bad breath. When selecting yoghurt, choose one with live and active cultures and minimal added sugar.

Milk

Drinking a glass of low- or full-fat milk during or after meals containing strong-smelling foods like garlic and onions can help neutralise bad breath by significantly reducing the concentration of volatile sulphur compounds (VSCs) [7]. Milk’s casein helps bind to these sulphur compounds, reducing their odour.

Fennel or anise seeds

Fennel seeds and anise seeds contain aromatic essential oils that give the breath a fresh scent. These seeds can be eaten plain, roasted, or coated with sugar and are commonly used in parts of India as “mukhwas,” or mouth fresheners. Their action is primarily due to their pleasant aroma masking the bad odour, while also stimulating saliva flow.

Orange

Oranges are rich in vitamin C, which may help increase saliva production. Saliva plays a crucial role in washing away foul-smelling bacteria from the mouth [2]. Eating oranges or other citrus fruits, such as lemons and grapefruits, may support dental hygiene and reduce bad breath. This is particularly helpful for individuals with mild dry mouth.

Zinc

Zinc is an effective mineral used in commercial mouthwashes and chewing gums because it helps inhibit bacterial growth and directly neutralises volatile sulphur compounds (VSCs) [8]. Using zinc-containing chewing gum or taking zinc dietary supplements can help combat bad breath, especially in cases of dry mouth. Consult a healthcare provider before starting any dietary supplement.

Dietary Tips to Prevent Bad Breath

Follow these tips to prevent bad breath:

• Eat crunchy fruits and vegetables: Foods like apples, celery, and carrots help cleanse your mouth by removing bacteria and increasing saliva production due to their high fibre and water content [2].
• Avoid sugary and refined foods: These foods can feed harmful bacteria in your mouth, leading to bad breath.
• Avoid strong-smelling foods: Foods like onions and garlic can cause temporary bad breath. While effective for some, eating a dairy product afterwards can help neutralise the odour.
• Hydrate regularly: Drink plenty of water to keep your mouth moist and prevent dry mouth.
• Chew sugar-free gum: This stimulates saliva production and helps clean your mouth.

When to see a doctor

If you’ve tried various home remedies and your bad breath persists, it may be time to consult a doctor. Persistent bad breath, especially when accompanied by other symptoms such as a sore throat, fever, or difficulty swallowing, may indicate an underlying health issue.

Gum disease, sinus infections, diabetes, and gastroesophageal reflux disease (GERD) are some conditions that require medical attention to treat the root cause of bad breath effectively [1].

Conclusion

Bad breath is often a result of poor oral hygiene, dry mouth, or dietary habits, and in most cases, it can be effectively managed at home. By following simple yet powerful remedies, such as staying hydrated, maintaining good oral hygiene, using natural ingredients like baking soda, yoghurt, and parsley, and improving your diet, you can significantly reduce bad breath.

Remember that persistent halitosis may be a symptom of a deeper medical issue, therefore, if symptoms persist, consult a dentist or healthcare provider to rule out underlying health conditions.

Expert Quote: “Most cases of bad breath are caused by bacterial buildup due to poor oral hygiene or dry mouth. Fortunately, simple remedies like tongue cleaning, chewing on herbs like parsley or fennel, and staying well-hydrated can significantly help. However, if bad breath does not resolve within a week of consistently applying these measures, a dental check-up is warranted to rule out periodontal disease or other issues.”
