What Are Some Home Remedies That Can Ease Bad Breath?


Bad breath is a typical problem, and there are several reasons. Possible solutions include green tea, water, or herbal wash, smelly tooth.

A persistent unpleasant breath or halitosis is usually caused by bacteria that reside in the mouth. The bacteria release gases that cause the smell. The smell is caused when bacteria breakdown starches and sugars in the food items we eat.

Sometimes, halitosis could indicate the presence of something much more severe, like gum diseases as well as tooth decay. It is essential that patients attend regular dental examinations to ensure that the dentist is able to tackle these issues at an early stage.

The halitosis can also be a sign of an issue with health within the body.

This article provides eight home remedies to treat bad breath. We also give suggestions on when to visit the doctor.

Herbal Rinses

Gum inflammation also known as gingivitis are the most common causes of halitosis.

A 2014 study conducted by Trusted Source looked at the effects of a natural mouth rinse on gingivitis, plaque and oral bacteria. The mouth rinse contained cloves, tea tree oil and basil, each possessing antimicrobial and anti-inflammatory properties.

Researchers split 40 people into two different groups. For 21 days the one group was using an oral rinse that was commercially available and the other group utilized the natural rinse.

Patients who used either rinse saw significant reductions in gingivitis and plaque. But the herbal rinse significantly reduced levels of bacteria present in the mouth while commercial rinses did not.

These results suggest that a mouthwash with tea tree oil, clove and basil, could help to improve the health of your mouth which could reduce the risk of the risk of halitosis.

Tea oil from trees

Tea tree may help fight some bacteria present in the mouth.    

Certain mouth bacteria produce chemicals called Volatile sulfur compounds (VSCs). These chemicals rapidly transform into the gases the cause of bad breath.

A study published in 2016 found the tea tree oil could reduce levels of the bacteria that cause VSCs.

The researchers isolated bacterial cultures from P. gingivalis as well as Porphyromonas endodontalis from the lab. Then, they treated the colonies with Tea tree oil or chlorhexidine. Chlorhexidine is an antimicrobial standard that is commonly used in mouthwash.

Effects of the tea tree oil are comparable to the effects of chlorhexidine. Both slowed development of the two strains, and also cut down on VCS production.

The findings of this laboratory study are positive. But, in the future, studies must be conducted to determine what the effect of the tea tree oil on the oral environment of the human.

It is important to note it is true that tea tree oils has less negative side consequences than chlorhexidine. Many people would prefer tea tree oil to find a natural substitute.

To make a tea-tree oil wash, mix one drops of tea tree oil into some drops of vegetable oil, and place it in an ice-cold cup. The solution should be sprayed into the mouth for about 30 seconds, and then flush it out once you’ve used all of the amount of the water. Do not swallow tea tree oil since it could be poisonous in the event of ingesting it.

Cinnamon oil

A laboratory research in 2017 about the effects of cinnamon oil on S. moorei bacteria.

Cinnamon oil has strong antibacterial properties against S. moorei. It also decreased levels of the VCS hydrogen sulfur.

The study also revealed that the oil of cinnamon did not cause harm to gum cells in humans.

They found that adding cinnamon oil in products for oral hygiene may assist in controlling the condition known as halitosis. However, further research involving humans are needed to verify this claim.

The user should not apply the essential oil directly on skin without diluting the oil in an oil carrier first. Cinnamon oil is available as a food-grade essential oil as well as an oil. The public is not allowed to swallow essential oils.

Aromatic spices and herbs

Certain spices are infused with aromatic essential oils. They may be able to help reduce the smell of breath after eating garlic or other foods that are a bit sour.

For a fresh breath after eating, one may try making an herbal tea that cleanses the palate. To make the tea, simply add some or all the spices into hot water and let it sit for a couple of minutes:

  • fennel seeds
  • Star anise
  • cloves
  • cardamom
  • cinnamon
  • Grated ginger

It is also possible to add one of these strong smelling plants:

  • spearmint
  • peppermint
  • parsley
  • cilantro
  • rosemary
  • Thyme

A lot of these spices and herbs also contain antimicrobial substances which fight bacterial causes of bad breath.


Kefir is a milk fermented drink that is similar to probiotic yogurt but with even more probiotic bacteria.

A study conducted in 2018 looked at the effects of various types of probiotic treatments on the levels of bacteria present in the mouth. The study lasted for six weeks and involved 45 participants.

Researchers classified them into 3 groups of participants:

  • Group Kefir: Participants drank 100 milliliters of kefir two times each day.
  • Probiotic toothpaste (PT) group: Participants used a probiotic toothpaste two times a day.
  • Group Control: The participants received nothing.

The kefir group as well as the PT group both showed a substantial reduction in S. mutans and Lactobacillus bacteria as researchers compared them with those in the group that were not.

These results suggest that drinking Kefir can help reduce levels of harmful bacteria in the mouth.
