Buyer’s Guide

When choosing the best probiotic for bad breath, there are a few factors you need to take into consideration – the ingredients, the size of the package, and how to store it. The dental probiotic you end up choosing might also depend on your budget.

It’s always best to consult with a doctor before you make this type of decision. Since dental probiotics can also be dietary supplements, they won’t only influence your oral health but also your digestive system. As long as you follow the instructions on the package, you should start feeling the effects of the pills soon.

These are the factors you need to think about when deciding which dental probiotic to use.


The ingredients in dental probiotics are the most crucial factor. Oral probiotics contain a certain amount of active bacterial strains that all serve different purposes. The best probiotic for bad breath needs to include the following:

  • Lactobacillus Reuteri
  • Lactobacillus Salivarius
  • Lactobacillus Paracasei
  • BLIS K12
  • BLIS M18

Many other bacterial strains are great for preventing bad breath, but these are some of the most effective. Each of them addresses an oral issue of some sort. For example, BLIS K12 (or Streptococcus Salivarius K12) is used to provide immune support to your oral health. On the other hand, the Lactobacillus Reuteri strain is good for treating and preventing bleeding gums and gingivitis.

Some probiotic pills have higher levels of active ingredients than others, so you should be careful not to take too many. In addition, some probiotics should be taken once a day, while others are safe to consume two to three times a day. In any case, be sure to read the instructions before you take them.

Probiotics are also generally made from natural, healthy ingredients. It’s possible to find dental probiotics that contain no sugar, gluten, lactose, GMOs, preservatives, artificial colors, artificial flavors, and similar. These types of products are also safe for vegetarians to consume.


The size of the dental probiotic is another thing to think about. Oral probiotics can be found in different forms – mouth rinse, lozenges, milk, drinks, pills, chewable tablets, even toothpaste. Out of all these types of dental probiotics, chewable tablets are the most effective. Probiotics can also take the form of pills that are supposed to be swallowed, but they’ve been proven to be less effective.

If you opt for chewable tablets, one package usually contains about 60 tablets. Some smaller packages have 450, and others 120. It ultimately depends on how often they should be consumed. For example, a package of 60 tablets that should be taken once a day will last the same amount of time as a 120-piece package with pills that should be taken twice a day.

Storage Information

The question of how your dental probiotics should be stored also depends on their form. Chewable tablets usually expire after a year and a half. In most cases, they should be kept in a cool, dry place. These types of oral probiotics typically don’t need to be refrigerated. While you can do this, you might risk changing their flavor.

Make sure you check the expiration date on the package.


Can Probiotics Cure Bad Breath?

It’s a scientifically proven fact that dental probiotics can cure bad breath.

While there are many things you can use to get rid of bad breath, such as breath mints and mouthwash, these are only temporary solutions. These dental aids minimize any harmful bacteria in your mouth, but they also wipe out the beneficial bacteria. Dental probiotics are the way to cure halitosis in the long run.

Most people aren’t aware of this fact, but there are more than 700 different types of bacteria in the mouth. However, not all of them are harmful. According to one study, the most effective way to cure halitosis is by maintaining a healthy amount of beneficial bacteria in the oral cavity. The reason they work so well is because they take effect directly in your mouth.

Dental probiotics can do more than just reduce bacterial growth in your mouth. Another study suggests that probiotics can also enhance your mouth’s immune system, alter the pH levels, and improve the quality of your saliva. These factors can reduce gum disease, gum bleeding, gingivitis, periodontitis, tooth decay, and other bacteria-caused issues.

Should I Take Oral Probiotics in the Morning or at Night?

When you take your oral probiotics entirely depends on you. What’s important is to take them after you’ve brushed your teeth. Some dentists suggest you consume them in the morning after you’ve finished your morning dental hygiene routine.

Others claim that’s it’s much wiser to take them right before you go to sleep. The reason why this method is better is that you’re not supposed to eat or drink anything after you’ve taken a probiotic. You should wait at least 30 minutes before you consume anything else. That being said, the choice of when to take your oral probiotics is yours.

How Long Do Oral Probiotics Take to Work?

The question of how long it will take your dental probiotics to work depends on many factors. For example, the type of probiotics, as well as the severity of your halitosis, might influence how quickly they’ll become effective.

If you have a mild case of halitosis, then it might take seven days to take effect and for you to start noticing any changes. That’s why it’s essential to give them some time to work, as you won’t see any results after only a couple of days. For those with a more severe case of halitosis, it might take two to three weeks for the probiotic to start working.

You’re supposed to take them until your halitosis is cured. The entire period of treatment might take from two to three months.

How to Take Oral Probiotics?

Always follow the instructions written on the package. If you’re taking the chewable tablets, it’s best to leave them in your mouth for 15 to 30 seconds. Then, let them dissolve to take full effect. Probiotics should always go after your dental hygiene routine, whether you’re taking them in the morning or night.

After taking a probiotic pill, make sure not to eat any food or drink anything for at least 30 minutes.

Aside from the dental probiotics, you can eat various types of food to help speed up the treatment. For example, apples, bananas, leeks, onions, garlic, kimchi, pickles, and cocoa are all prebiotic foods that provide fibers essential for the growth of beneficial probiotic bacteria.

Find the Probiotic That Works for You

Halitosis is a common condition that every fourth person suffers from. While many temporary fixes will mask bad breath, the most effective solution is a dental probiotic. Not only will it make your breath fresh, but it will also make your mouth and upper-respiratory system healthy.

All of the probiotics we mentioned are worth a try, but if we had to pick a winner, the best probiotic for bad breath would be the Chewable Oral Probiotics for Mouth by Great Oral Health. This product contains up to seven beneficial probiotic strains, natural supplements, and two different flavors. Furthermore, it will boost your immune system, all the while maintaining your oral health. Take two pills a day, and you’ll surely, but slowly, start to notice the results.
