The proper oral care needed to get rid of bad breath and prevent it from coming back.

Have you ever been disappointed by an oral care product's claim that it will eliminate your bad breath only to find that it only masks your bad breath temporarily? Read this article in order to discover how to truly get rid of bad breath. It is not as easy as the market would have you believe, but it is possible with the right knowledge, tools, and actions.

A Brief Overview of What Causes Bad Breath

Bad breath is caused by an overgrowth of anaerobic bacteria producing foul smelling gasses due to one or more of the following:

This article is going to focus on treating the main cause of bad breath: Poor oral hygiene. 90% of the cases of halitosis are due to anaerobic bacteria in the mouth, and proper oral hygiene can usually fix it. If you suspect that it might be caused by one of the other causes of bad breath such as dry mouth, sinus/throat/oral infections, post nasal drip, allergies, tonsil stones, or gum diseases - seek help from a qualified professional or read our articles on those specific causes.

If you are serious about getting your bad breath under control and if you haven't been to the dentist in the past year, you need to visit the dentist and get a check-up and a cleaning. You may have some oral problems that you don't know about that are causing bad breath. Tartar and plaque contribute to the growth of bacteria so it would be a good idea to get a good cleaning to remove as much of that as possible.

How to Get Rid of Bad Breath

Since we know what causes bad breath: Friendly Environment + Food + Time, we can figure out how to eliminate bad breath. The equation is fairly simply:

Remedy for Bad Breath

  1. Get rid of proteins the bacteria eat
  2. Create a unfriendly environment for the bacteria
  3. Time

We will now go through each of these steps and elaborate on what it means.

1. Get rid of proteins the bacteria eat

Contrary to what the oral care market would have you believe, which toothpaste or mouthwash you use is not that important. What is most important in getting rid of bad breath and preventing it is the consistent mechanical removal of the proteins and particles that anaerobic bacteria feed upon. Going directly after anaerobic bacteria with harsh chemicals such as alcohol in mouthwashes and other antibacterial substances doesn't work as well as one would think. Try it, gargle and swish Listerine after every meal without practising any other oral care and you will find that bad breath returns quickly despite what advertising would leave you to believe. The consistent mechanical removal of the proteins is largely dependant on your technique and the tools you use to remove those proteins such as toothbrushes, floss, tongue scrapers, etc and not the pastes or liquids you buy.

In order to remove the proteins (food particles, dead cells, mucus) the bacteria eat, you need to do more than just brush your teeth. A proper oral care regimen depends on each individual. For example if you have braces, you need to do specific procedures in order to properly clean your teeth. If you have partially erupted wisdom teeth, you need to properly irrigate them. If you suffer from post-nasal drip or allergies, you need to incorporate nasal irrigation into your daily oral care regimen. If you suffer from tonsil stones, you need to remove them regularly.

A Comprehensive Oral Care Regimen

A comprehensive oral care regimen for your average person consists of the following in order of which you do them:

2. Create a unfriendly environment for the bacteria

A mouth that is low in oxygen, is slightly acidic, and that is dry is a prime place for anaerobic bacteria to colonize. In order to create a more uninhabitable environment you need to make sure your mouth isn't dry, is slightly alkaline, and has oxygen.

Saliva contains oxygen so it is important to have good saliva flow in your mouth. In order to increase saliva flow it is important to drink plenty of fluids throughout the day. Also when your mouth feels dry chew on a piece of sugar-free gum or suck on a mint. If you suffer from chronic xerostomia (dry mouth), you should look into products that contain saliva stimulants or substitutes. Check out this list of dry mouth products.

Other than increasing saliva flow, another way to increase oxygen that kills bacteria is to gargle mouthwashes that contain oxygenating chemicals such as hydrogen peroxide. There are also toothpastes that contain these chemicals. Therabreath is a company that contains oxygenating compounds in their products.

In order to lower the acidity in your mouth, you can avoid acidic and spicy foods, or use products that lower acidity. Baking soda is excellent at lowering acid levels. After your oral care regimen or after you eat, you can swish a sodium bicarbonate (baking soda) solution for a minute and then spit it out. Do not rinse your mouth out after.

During the day most people snack on food. Although it is not absolutely necessary to brush your teeth after each snack, it is a good idea to snack on foods that minimize bad breath. Read our article on foods that foods and drinks that prevent bad breath. It is also a good idea to be aware of and avoid foods and drinks that cause bad breath.

Probiotics can also create competition in your mouth for the bacteria, where friendly bacteria are competing for the same space as the anaerobic bacteria. Read more about this in our oral probiotics article.

Although creating an unfriendly environment for the anaerobic bacteria is effective, getting rid of the food source for anaerobic bacteria through proper oral care as outlined above is much more important. This step should be thought of as a bonus, because doing this alone will not get rid of bad breath. Creating an unfriendly environment for bacteria is more of a preventative measure against bad breath, rather then a tool for getting rid of it.

3. Time

There is no magic mouthwash, toothpaste, or gum that will get rid of your bad breath and prevent it from coming back. Getting rid of bad breath is not an instant process. It requires patient consistent effort. Do not give up immediately after trying the full oral care regimen above because you notice that your bad breath returns a couple hours later. It takes weeks to reduce the population of anaerobic bacteria to a healthy low level. If you are serious about treating your bad breath or about preventing it from coming back, you need to put in the time and effort. The full oral care regimen above can take awhile, but it is worth it in the end. We know you might lead busy lives, and it is hard to fit proper oral care in. We encourage you to read our article Oral Care on The Go to learn how to maintain fresh breath despite your busy schedule.

How To Prevent Bad Breath From Returning

Preventing bad breath from returning is continuing the same process you used to get rid of your halitosis in the first place: regular dental check-ups from professionals, consistent proper oral hygiene, and avoiding foods and drinks that cause bad breath. If you do the entire oral care regimen listed above each night before bed, you will be on the right track on preventing bad breath from coming back.
