How to Get Rid of Bad Bacteria in Your Mouth for Good

Maintaining good oral hygiene is essential to your overall health. One of the best ways to protect your oral health is by removing bad bacteria from your mouth. In this article, we’ll discuss 20 ways to get rid of bad bacteria and maintain a healthy, clean mouth.

1. Brush twice a day

Brushing your teeth twice a day is important to remove bacteria that can cause bad breath, tooth decay, and gum disease. Use a fluoride toothpaste and a soft-bristled toothbrush to clean your teeth for two minutes each time.

2. Floss daily

Flossing helps remove food particles and plaque that your toothbrush can’t reach. Floss at least once a day to prevent bacteria buildup between your teeth and gums.

3. Use mouthwash

Mouthwash can help kill bacteria that cause bad breath and gingivitis. Swish it around in your mouth for 30 seconds after washing your teeth.

4. Drink water

Drinking water helps remove food particles and bacteria from your mouth. It also keeps your mouth moist, preventing dry mouth that can cause bad breath.

5. Chew sugar-free gum

Chewing sugar-free gum stimulates saliva production, which helps rinse away bacteria and food particles in your mouth.

6. Avoid sugary foods

Sugary foods can cause bacteria to grow in your mouth, leading to plaque and tooth decay. Avoid sugary snacks and drinks, and brush your teeth after eating them.

7. Eat healthy foods

Eating a well-balanced diet of fruits, vegetables, and whole grains can support your oral health and prevent bad bacteria from growing in your mouth.

8. Visit the dentist regularly

Seeing your dentist every six months for a checkup and cleaning can help remove plaque and bacteria buildup that regular brushing and flossing can’t reach.

9. Clean your tongue

Bacteria can accumulate on your tongue, causing bad breath and other health problems. Use a tongue scraper or brush to clean your tongue regularly.

10. Use a water flosser

A water flosser is an alternative to traditional flossing that uses a stream of water to clean between your teeth and gums.

11. Limit alcohol consumption

Alcohol can dry out your mouth, creating an environment for bad bacteria to grow. Limit your alcohol consumption, and drink plenty of water to stay hydrated.

12. Quit smoking

Smoking increases your risk of gum disease and oral cancer. Quitting smoking can improve your oral health and reduce your risk of these conditions.

Fluoride can help strengthen your tooth enamel and prevent tooth decay. Use a fluoride mouthwash as part of your daily oral hygiene routine.

14. Brush your tongue

Brushing your tongue as well as your teeth can help remove bacteria and prevent bad breath.

15. Use a straw

Drinking through a straw can help prevent sugary and acidic drinks from coming into contact with your teeth, reducing your risk of tooth decay and other oral health problems.

16. Don’t share personal items

Sharing personal items, such as toothbrushes, can spread bacteria and viruses that can cause oral and other health problems.

17. Wash your hands

Washing your hands regularly can help prevent the spread of bacteria and viruses that can cause oral and other health problems.

18. Use a mouthguard

Using a mouthguard can help protect your teeth and gums from injury during physical activities. It can also reduce your risk of infection if you play contact sports.

19. Chew on parsley

Parsley contains chlorophyll, which can help neutralize bad breath. Chewing on parsley after meals can help freshen your breath and promote good oral health.

20. Use probiotics

Probiotics are good bacteria that can help promote oral health and prevent bad bacteria from growing in your mouth. Look for probiotic supplements or foods that contain live cultures, such as yogurt and kefir.


Q: Can bad bacteria in your mouth cause health problems besides oral health problems?

A: Yes. Studies have linked periodontal disease to an increased risk of heart disease, stroke, and diabetes.

Q: What is dry mouth, and why is it a problem for oral health?

A: Dry mouth is a condition in which your mouth doesn’t produce enough saliva. Saliva helps rinse away bacteria and food particles in your mouth, so dry mouth can lead to bad breath, tooth decay, and gum disease.

Q: Are there any natural remedies for bad breath?

A: Yes. Besides chewing on parsley, some other natural remedies for bad breath include drinking green tea, chewing on cinnamon sticks, and eating crunchy foods like carrots and apples.

Q: How long should I brush my teeth for?

A: You should brush your teeth for at least two minutes each time, twice a day.

Q: What should I do if I have a toothache?

A: If you have a toothache, see your dentist as soon as possible. A toothache can be a sign of a serious oral health problem, and delaying treatment can lead to further damage and complications.


Maintaining good oral hygiene is important to your overall health.
