The Best Essential Oils for Oral Care

Did you know that your oral health has a deeper connection to your overall health? When we fail to properly clean and care for our mouth, teeth, and gums, we could be putting ourselves at risk for more serious health issues. Conversely, when we do practice regular oral hygiene, we are setting ourselves up for a healthier mouth and fewer problems in the future.

You probably have a few favorite oral hygiene products that you already use in your routine, but what if you want to go the extra mile and give your mouth a boost when it comes to cleaning? Thankfully, there are some essential oils that are safe to use for cleansing the mouth, teeth, and gums. At the same time, the potent nature of essential oils makes them useful for promoting fresh breath.

If you need some extra help when it comes to keeping your mouth fresh and clean, consider using some of the following doTERRA products during your daily oral hygiene routine.

Cinnamon Bark oil

You’ve probably noticed that cinnamon is used frequently in mouth rinses because it can be useful for freshening the breath and is a flavor that people enjoy. Similarly, Cinnamon Bark oil has cleansing properties that can be useful for cleansing the gums, mouth, and skin, and can help to maintain clean, healthy looking teeth. It is perfect for adding to DIY mouthwashes and is already an ingredient in the doTERRA On Guard® Whitening Toothpaste. Be aware, however, that Cinnamon Bark is also a “hot” oil, and should not be used undiluted on the skin. Tip: When you are traveling or on-the-go, combine a drop of Cinnamon Bark oil with two ounces of water, shake or stir well, and gargle to help cleanse the teeth, mouth, and gums.

doTERRA On Guard Whitening Toothpaste

Because there are certain essential oils that possess powerful cleansing properties for the mouth, doTERRA has created an essential oil-infused toothpaste designed to help keep the mouth clean and the teeth white. The doTERRA On Guard Whitening Toothpaste formula uses the proprietary doTERRA On Guard® essential oil blend of Wild Orange, Clove, Cinnamon, Eucalyptus, and Rosemary to clean and freshen breath. Plus, it includes Myrrh essential oil to sooth the mouth and throat, and Peppermint oil for minty flavor and freshness.

Unlike other whitening toothpastes, the doTERRA On Guard Whitening Toothpaste is not damaging to enamel, as it contains gentle polishing agents that are meant to remove plaque and tooth stains.

Tip: Try using the doTERRA On Guard Whitening toothpaste to brush your teeth after each meal or after consuming sugary snacks and drinks to prevent stains from settling into the teeth.

doTERRA On Guard® Mouthwash

A perfect pairing with the doTERRA On Guard Whitening Toothpaste, the doTERRA On Guard Mouthwash makes it easy to harness the power of the doTERRA On Guard blend for fresh breath and a clean mouth. Each essential oil in the doTERRA On Guard blend provides cleansing and freshening properties that will leave your mouth feeling fresh and clean after each use of the doTERRA On Guard Mouthwash.

Using an effective mouthwash is an easy way to give your mouth some extra care. The doTERRA On Guard Mouthwash formula is designed to help clean the teeth and gums, reduce plaque, provide fresh breath, and promote a healthy-looking mouth. When combined with brushing and flossing, this essential oil mouthwash will give your smile all the love it needs.

Tip: Use the doTERRA On Guard Mouthwash morning and night along with doTERRA On Guard Whitening Toothpaste for a brighter, cleaner smile.

Peppermint Beadlets

For those times when you would like fresh breath, but aren’t able to brush your teeth right away, doTERRA Peppermint Beadlets provide a quick fix. Tiny beadlets made with Peppermint essential oil will give you the refreshing cleanse your mouth needs. Whether you’ve just eaten lunch, or want to ward off bad breath in the morning, Peppermint Beadlets provide an easy way to step up your oral hygiene game.

Tip: Keep Peppermint Beadlets in your purse or car for those bad breath emergencies when you need a quick way to freshen your mouth.

Spearmint oil

Spearmint has been used widely for candies, gums, and dental hygiene products because of its pleasant, minty taste and ability to promote fresh breath. Spearmint oil is a milder alternative to some of the other strong mint oils, yet it still provides powerful cleansing and refreshing properties for the mouth. If you want to add some variety to your oral hygiene routine, using Spearmint as an alternative to stronger oils like Peppermint or Cinnamon is a great way to infuse a new flavor while still maintaining freshness.

Tip: Because Spearmint oil is mild yet effective, consider placing a drop of the oil on your child’s toothbrush before they brush their teeth to help promote fresh breath.

Throughout history, experts relied on windows into our health: the eyes to check on the soul, the mouth to gauge strength and longevity. Animals were bought and sold based on this window philosophy. Today, as in ancient times, the windows are more relevant than ever. There is mounting research to show that the overall health of your mouth does in fact mirror or represent the condition and health of your body. This research shows that maintaining a healthy oral cavity may be linked to overall long-term health and quality of life.

The Heart and Mouth Connection

According to the American Dental Association and the American Medical Association, there is a relationship between the condition of the gums and the condition of the cardiovascular system. Gum health is primarily a result of oral care, personal habits, and, to an extent, genetics. With appropriate effort and proper hygiene, threats to the health of our gums can be eliminated or controlled. However, failure to maintain gum health has other health consequences. Sub-optimal conditions of the heart can be traced to unhealthy gums, underscoring how important oral health care is.

Habits of Good Oral Health

Knowing that the oral cavity both reflects our bodies’ condition and impacts our physical health, it is imperative that we make a daily habit of a few simple, proactive maintenance measures.So what do we do? First, let’s assume that we have all made the decision to reduce or nearly eliminate processed sugar. When you eat food or drink beverages containing sugar or starch, your mouth becomes acidic for 20 minutes or more, creating a threat to gums and teeth. Second, we have made the decision to eat healthy balanced meals, incorporating healthy fats, lean proteins, complex carbohydrates, rough foliage, and low sugar fruits and vegetables, thus reducing food sources that compromise our oral health, creating a more healthy environment for the mouth.

Is there a time that's best to brush your teeth?

The American Dental Association recommends brushing your teeth twice a day. One of those times should be at bedtime, because if certain foods and drinks sit in your mouth for an extended duration they will create a serious threat to gums and teeth. Keep a toothbrush at work to brush after eating. Place two drops of doTERRA On Guard® on the bristles, and massage them into the teeth and gums. Brush your tongue while including doTERRA On Guard, Cinnamon, or Peppermint to promote clean and crisp breath. Toothpaste that is designed to neutralize low pH and freshen breath is excellent. To promote cleanliness try adding 3–4 drops of Melaleuca (Tea Tree) essential oil, or doTERRA On Guard and Spearmint on the toothbrush before adding your toothpaste.

Kids’ mouth guards are usually quite dirty. Try soaking the mouth guard in cool water with 5 drops of doTERRA On Guard and Peppermint. Floss at least once a day. Flossing removes food debris and plaque from between your teeth and in areas your toothbrush can’t reach. Try soaking your floss in a small cup with warm salt water and Melaleuca, then rinse with the mixture for increased cleanliness.   Following dental work, rinse with the warm salt water and essential oil rinse. The rinse will soothe the gums and promote a clean fresh mouth.   Chew only sugarless gum (preferably one with xylitol). Chewing gum stimulates saliva, buffering the pH of the mouth, and reducing plaque. Swish with a mouth rinse.  Try making your own: add 2 teaspoons of salt to 4 cups of warm water and mix well. Let cool if desired, then add 5 or more drops each of Melaleuca, doTERRA On Guard, Cinnamon, and Peppermint and 2 or more drops of Clove. Rinse for 30 seconds two times per day. This rinse is also an easy “at work remedy” for the dreaded post lunch smelly breath—your coworkers will thank you! Be sure to drink plenty of water, not coffee, soft drinks or alcohol, which can lead to a drier mouth. Remember, most flavored waters contain sugar, so water is always best.
