What Home Remedies Can Help With Bad Breath?

Bad breath is a common issue, and there are many different causes. Potential remedies include water, green tea, and herbal rinses.

Persistent bad breath, or halitosis, is usually due to bacteria in the mouth. These bacteria produce gases that can cause a smell. The odor occurs when the bacteria break down sugars and starches in the foods people eat.

Sometimes, halitosis may signal something more serious, such as gum disease or tooth decay. It is important that people go for regular dental checkups so that a dentist can treat these issues early.

Halitosis could also signal an underlying health issue elsewhere in the body.

This article outlines eight natural home remedies for bad breath. We also provide tips on when to see a doctor.


Dry mouth is a condition that can cause halitosis as well as other oral health problems.

Dry mouth occurs when the salivary glands inside the mouth do not produce enough saliva to rinse food debris from the mouth. This helps to control levels of oral bacteria.

Many different factors can cause dry mouth. The most common cause is dehydration. Medications and diet can also influence the moisture in the mouth.

Green tea

Green tea is an antioxidant-rich tea made from the leaves of the Camellia sinensis plant.

The most abundant antioxidant in green tea is Epigallocatechin-3-gallate (EGCG). Research suggests EGCG may have many beneficial effects on health.

Both green tea extract and EGCG reduced the growth of S. moorei cultures, although green tea extract showed the greatest effects. This suggests that other chemicals within green tea may also have antibacterial properties.

Herbal rinses

Dental plaque and gum inflammation, or gingivitis, are common causes of halitosis.

A 2014 study investigated the effects of an herbal mouth rinse on plaque, gingivitis, and levels of oral bacteria. The rinse contained tea tree oil, cloves, and basil, each having antimicrobial and anti-inflammatory properties.

Researchers divided the 40 participants into two groups. Over 21 days, one group used a commercial mouth rinse, while the other used the herbal rinse.

Participants who used either rinse showed significant reductions in plaque and gingivitis. However, the herbal rinse also significantly reduced levels of bacteria in the mouth, whereas the commercial rinse did not.

These findings suggest that a mouth rinse containing tea tree oil, clove, and basil, may help to improve oral health, so reducing halitosis.
