Find out everything you need to know about Smile Guard and how it works today in our review.

What is Smile Guard?

Smile Guard is an oral health supplement featuring a blend of three active ingredients to support your mouth’s microbiome.

Your mouth, like your gut, is filled with living bacteria. When these bacteria become imbalanced, it can increase the risk of bad breath, tooth decay, and even gum disease, among other issues.

By taking Smile Guard daily, you can promote your body’s natural defense against oral health problems. Some take Smile Guard to freshen their breath. Others take the supplement for a cleaner mouth overall.

Smile Guard is priced at $59 per bottle and backed by a 60-day moneyback guarantee. The supplement is exclusively sold through Humarian.com.

Smile Guard Benefits

Some of the benefits of Smile Guard, according to the manufacturer, include:

• Fight back against the root cause of bad breath and tooth decay
• Promote your body’s natural defense against oral health problems
• Formulated by doctor
• Third-party tested
• Blend of IgY, vitamin D, and xylitol
• Backed by a 60-day satisfaction guarantee

How Does Smile Guard Work?

Smile Guard uses a blend of probiotics to seek out bad bacteria currently living in your teeth and gums.

For various reasons, your mouth becomes overloaded with bacteria over time. Normally, your mouth can fight off these bacteria. Over time, however, your mouth becomes overwhelmed, causing a probiotic imbalance in your mouth.

When your mouth is overwhelmed by bacteria like Streptococcus mutans, it increases the risk of gum disease, tooth decay, halitosis, and other oral health problems. Some develop yellow and stained teeth. Others have embarrassing bad breath, cavities, and other oral health issues.

By taking Smile Guard daily, you can purportedly “naturally eliminate bad bacteria” linked to cavities, bad breath, and tooth decay.

To do that, Smile Guard uses a blend of three active ingredients, including vitamin D, xylitol, and a unique egg yolk protein/probiotic called IgY.

What is the “Odd Egg Yolk Trick”?

Dr. Ryan Bentley, the physician who created Smile Guard, developed the supplement based on an “odd egg yolk trick.”

Dr. Bentley describes the egg yolk trick as “one of the top dental health hacks in the industry.” It can help freshen your breath and restore teeth in just 30 seconds per day.

Egg yolk works because it’s rich in a natural molecule called immunoglobulin Y (IgY). Discovered in 1893, IgY is an immune cell that helps eggs defend themselves against foreign pathogens as the chick grows. Dr. Bentley describes the molecule as “border patrol” for chicks growing in the egg.

Today, when taken daily, that same molecule can help target harmful bacteria like S. mutans and P. gingivalis. The same harmful bacteria increase the risk of tooth decay and gum disease.

Instead of swishing an egg yolk in your mouth, Dr. Bentley recommends a different approach: by taking Smile Guard daily, you can promote your body’s natural production of immune biomarkers, boosting your mouth’s ability to defend itself from harmful toxins.

Smile Guard Ingredients

Smile Guard contains three active ingredients linked to oral health: an IgY probiotic protein, vitamin D, and xylitol.

Here are all three active ingredients in Smile Guard and how they work to promote oral health:

• IgY Probiotic Protein: Dr. Ryan Bentley developed Smile Guard as part of an “egg yolk trick.” Researchers found a specific immune protein in egg yolk called immunoglobulin Y, or IgY, could promote oral health in a significant way. Today, Smile Guard contains that same IgY protein to promote oral health. In a 1997 study, researchers analyzed the effects of mouthwash with egg yolk antibodies (IgY). Researchers found these antibodies were effective against Streptococcus mutans, one of the most common causes of oral health issues – like tooth decay and gum disease. Because of these results, researchers suggested egg yolk with IgY could be “an efficient method” to control S. mutans colonization.
• Vitamin D: Vitamin D is a crucial nutrient involved in hundreds of important processes throughout the human body. It’s particularly important for immune function and hormone production. Your skin produces vitamin D when it encounters sunlight. However, if you’re deficient in vitamin D or not getting enough vitamin D, your oral health could suffer. A 2020 study on Nutrients found vitamin C deficiency was linked to an increased risk of periodontitis, cavities, and even oral cancers, among other serious health risks.
• Xylitol: Xylitol is a five-carbon sugar polyol used as an alternative to sugar. Sugar can increase the risk of dental cavities. By replacing sugar with xylitol, you could lower your risk of cavities. One 2014 study found xylitol had promising potential for “reducing dental caries,” or cavities, while also reversing the progress of early cavities, among other benefits. Xylitol could also have natural antibacterial effects. One study found xylitol intake caused a significant decrease in mutans streptococci (MS) in the plaque and saliva, suggesting xylitol could help manage the risk of cavities, gum disease, and tooth decay.

Other, inactive ingredients in Smile Guard include maltitol, calcinated shell calcium, polydextrose, cellulose, calcium stearate, orange flavor, hydroxypropyl cellulose, and silicon dioxide. Many of these ingredients create the dissolving lozenge that helps Smile Guard deliver its active ingredients.

How to Take Smile Guard

Dr. Bentley and his team at Humarian recommend taking one lozenge daily for oral health:

• Take 1 lozenge by slowly dissolving it in the mouth and occasionally swallowing
• Avoid eating or drinking for 30 minutes after use
• Do not chew the lozenge
• Start with taking 1 lozenge twice per day for 7 days. Then, increase to 1 lozenge, 4 times per day for 30 days. For severe cases, take 1 lozenge, 6 times per day, for 30 days.

After 30 days, maintain oral health by taking 1 lozenge in the morning and 1 lozenge before bed.

What to Expect After Taking Smile Guard

Some take Smile Guard for bad breath. Others take it to help with tooth and gum health.

Here are some of the results you could expect after taking Smile Guard, according to the official website:

• Promote Fresher Breath: Many people find Smile Guard helps with halitosis, the root cause of bad breath in some people. Bacterial imbalances within the mouth cause halitosis. You can use multiple probiotic strains to promote fresher breath by taking Smile Guard daily. Humarian claims many customers “see improvements in their breath within the first few days” when using Smile Guard.
• Fight Cavities: Studies show probiotics help create a biofilm over teeth, which forms a protective layer against cavities, gum disease, and harmful pathogens. According to Humarian, Smile Guard can “naturally restore your oral microbiome and fight cavities. “
• Promote Oral Health Over 12 to 16 Weeks: Humarian doesn’t advertise Smile Guard as a miracle, overnight solution to tooth and gum disease; instead, they advertise it to promote oral health long-term. According to the manufacturer, “your oral health will continue to get better over the next 12-16 weeks” of using Smile Guard. Some notice results – like better breath – within days. Others experience a noticeable improvement in tooth health much sooner.
• Restore Teeth & Gum Health: The overall goal of Smile Guard is to use a unique blend of IgY probiotics to restore tooth and gum health overall. An imbalanced oral microbiome makes it difficult for your body to fight off infections in your mouth. Taking Smile Guard daily could restore your oral microbiome and promote tooth and gum health.
• Fight Tooth Decay: Tooth decay occurs when harmful bacteria colonize the mouth and produce toxins that damage the teeth and gums. These bacteria chip away at teeth, leading to decay. By promoting a balanced oral microbiome, Smile Guard could help fight tooth decay.
• Fight Back Against Swollen Gums: Bacterial imbalances in the mouth could lead to swollen, inflamed gums. Smile Guard aims to help fight back against painful, swollen gums with a blend of three active ingredients.
• Promote Bright, Healthy Teeth: Poor oral microbiome health could worsen the appearance of teeth and gums. Smile Guard promotes bacteria linked to brighter teeth and a balanced oral microbiome.
• Avoid Toxic Mouthwashes & Dangerous Dental Treatments: Smile Guard is an easy-to-take, doctor-formulated, daily lozenge. It can help you avoid toxic mouthwashes or abrasive solutions to your oral health problems. According to Dr. Bentley and his team at Humarian, store-bought mouthwash “damages your teeth and gums” while increasing the risk of bad breath and cavities. These mouthwashes destroy your mouth’s natural oral microbiome and imbalance pH levels, increasing the risk of oral health problems.
• Fight the Root Cause of Oral Health Problems: Dr. Bentley developed Smile Guard not just to target symptoms of oral health problems but to fight the root cause of cavities and tooth decay. That root cause is streptococcus mutans, the bacteria responsible for cavities and tooth decay. The bacteria lodges in your teeth and gums, increasing the risk of oral health problems.

Ultimately, Smile Guard’s goal is to give your body the ingredients needed to promote its own oral health. Instead of using toxic mouthwashes or other invasive solutions, you can promote oral health using the proven power of IgY probiotic protein—the same protein found in egg yolks.

Scientific Evidence for Smile Guard

Humarian has conducted trials on its probiotic supplements to verify that they work as advertised. The company also cites third-party scientific evidence to validate the use of Smile Guard on your oral microbiome. We’ll evaluate the science behind Smile Guard below.

In one of the largest reviews on probiotics and oral health, researchers found probiotic supplements could help with bad breath (halitosis) while improving the overall quality of life linked to oral health. Researchers also found a correlation between a balanced microbiome in children and a reduced risk of cavities. Generally, kids with a healthy microbiome tended to have a lower risk of cavities.

Humarian also distinguishes its probiotics from other supplements by advertising 10 to 12x better bioavailability than other leading probiotic supplements. According to the manufacturer’s research, Humarian probiotics pass through the TIM-1 system more effectively than other competing probiotics. As proof, Humarian tested a leading probiotic supplement and found more Lactobacilli and Bifidobacteria passed through the gut with Humarian than with the competing product.

As Humarian explains, some probiotic strains are explicitly linked to decreased plaque formation and other oral health effects. L. salivarius, for example, “dramatically decreases the level of plaque-forming bacteria in the mouth,” according to the manufacturer. At the same time, Lactobacillus reuteri is known for “killing off certain kinds of bad bacteria that can cause tooth decay.” Both of these strains are found in Smile Guard.

Some studies suggest probiotics work because they help create a biofilm. This biofilm acts as a protective lining, defending your teeth and gums against harmful pathogens. One study found people with a balanced microbiome tended to have a reduced risk of cavities, oral infections, and periodontal disease because of this biofilm.

Multiple studies have linked probiotics to oral health, and some take probiotics like Smile Guard daily to promote oral health.
