Halitosis, or bad breath, is characterized by an unpleasant odor in the mouth, a condition that can cause a lot of discomfort. Because it’s embarrassing, it can cause those who suffer from it to lose their self-confidence and self-esteem among their circle of friends. Fortunately, there are many natural remedies for bad breath.

Bad breath is often caused by poor oral hygiene habits, but it can also be related to the consumption of certain foods, smoking, or having a dry mouth, as well as other factors. The remedies we’ll show you help to slow bacterial growth, neutralize the odor, and improve your oral health.

While commercially available mouthwashes can be very effective, today we’ll be sharing natural remedies for bad breath that are just as effective, and won’t break the bank!

Home remedies to freshen your breath

1. Baking soda

A bowl of baking soda.

Baking soda is one of the most common products for treating halitosis. Thanks to its antimicrobial properties it helps control the growth of bacteria and neutralizes odors and possible infections. It’s important to use caution when trying this remedy because baking soda is also a powerful abrasive.


  • 1 teaspoon of baking soda (5 g)
  • 1/2 cup of warm water (100 ml)

How do you make it?

  • Dilute the baking soda in a half a cup of warm water and then gargle the mixture two to three times a day.

2. Tea tree essential oil

Being a powerful antiseptic, tea tree essential oil is a natural disinfectant that fights the growth of bacteria in the mouth and controls bad breath. If you want to try tea tree oil, make sure you proceed with caution. Tea tree oil could cause irritation.

  • 5 drops of mint oil
  • 3 drops of lemon oil
  • 1/2 cup of warm water (125 ml)

  • Firstly, soak the parsley leaves in apple cider vinegar for 15 minutes.
  • After that, chew them for a few minutes.
  • Repeat this remedy after you brush your teeth.

4. Apple cider vinegar

Apple cider vinegar contains acetic acid, a substance that lowers the pH of the mouth, thus creating an unfriendly environment for microorganisms to proliferate. 


  • 3 tablespoons of apple cider vinegar
  • 1 cup of water

How do you make it?

  • Mix the apple cider vinegar and water together and then use it as a mouthwash.

5. Lime

  • Firstly, bring the cup of water to a boil and add the mint leaves. Then allow it to simmer for five minutes before straining the liquid. Drink this tea after every meal.

7. Nettle tea

A cup of nettle tea.

Many people believe that nettle tea is a naturally cleansing beverage that stimulates the removal of toxins and heavy metals that could cause bad breath. However, there isn’t yet any scientific evidence to back up that claim.

How do you use it?

  • Chew up a few fennel seeds after each meal

9. Fenugreek tea

Fenugreek seeds with a wooden scoop.

Fenugreek has numerous health benefits, but there is no scientific evidence to confirm the benefits of fenugreek for people with halitosis. That being said, you can try it if you’d like.


  • 1 teaspoon of fenugreek seeds (5 g)
  • 1 cup of water (250 ml)
