Unanticipated Benefits of Using Licorice Root for Teeth

In this detailed guide, you will discover the surprising benefits of licorice root for teeth. Learn how this root can enhance your dental care routine.

Want to prevent cavities naturally and maintain good oral health, steering clear of synthetic ingredients? Well, licorice root is the right choice for you! Let’s assess this versatile little plant and its many, many advantages!
But wait, before we proceed, let’s learn a bit about the importance of oral health.


Why is Maintaining Oral Health a Good Idea?

Oral health greatly influences our general well-being and quality of life. A healthy mouth contributes not only to better digestion, clear speech, and a confident smile but it also prevents various dental issues like cavities, gum disease, and bad breath, ultimately reducing the risk of more serious health problems such as heart disease and diabetes. Regular oral hygiene practices, like brushing, flossing, and dental check-ups, play a vital role in improving our dental health and overall well-being.

Amid the wide array of dental products available today, natural plant-based alternatives are popular. This root is one such alternative and is commonly used for its numerous health benefits.


What is Licorice Root?

licorice root for teeth

Liquorice is a sweet, moist, soothing herb that belongs to the glycyrrhiza species native to Mediterranean countries and Asia. It has been mentioned in ancient Ayurvedic texts as “Atirasa”, and the dried unpeeled roots of Glycyrrhiza glabra Linn are the most common source. Liquorice, also known as gancao – meaning “sweet herb” in Chinese – has been used by humans for over 4000 years to soothe an upset stomach, reduce inflammation, and treat upper respiratory tract problems. Quite remarkable, isn’t it?

While it contains hundreds of plant compounds such as glabridin, licoricidin, and licorisoflavan that aid in its medicinal prowess, licorice root’s primary active compound is glycyrrhizin. It is responsible for the root’s sweet taste, as well as its anti-inflammatory, antioxidant and antimicrobial properties.


How Does Licorice Root Benefit Oral Health?

Utilizing licorice root as part of DIY dental care provides various health benefits such as fighting off harmful bacteria, reducing inflammation, and preventing cavities and gum disease, not to mention that it freshens breath.

Come along, let’s delve deeper into the numerous oral health benefits provided by this amazing plant!

1. Fighting Bacteria and Preventing Tooth Decay

Licorice root has proved to be effective in preventing tooth decay due to its antibacterial properties. In a recent study examining licorice’s antibacterial potency, participants consumed sugar-free orange-flavored licorice lollipops containing glycyrrhizol A, twice daily for 10 days. 

The study demonstrated a significant decrease in salivary S. mutans, the primary bacteria associated with tooth decay, confirming its effectiveness. Did you know that this root along with its anti-cariogenic activity also aids in teeth whitening? Pretty cool, heh! However, further research is needed to establish the optimal dose and form for safe and effective usage.

Reducing Inflammation and Treating Gum Disease

2. Reducing Inflammation and Treating Gum Disease

Among its many advantages, licorice root offers anti-inflammatory and anti-microbial properties that help fight gum disease by inhibiting the growth of harmful bacteria such as P. gingivalis and preventing plaque buildup to ensure good oral health. It also reduces pain and discomfort, making it a useful natural remedy and a viable alternative to synthetic ingredients!

3. Natural Alternative for Mouth Freshness

One of the problems with mainstream mouthwashes is that they’re way too powerful. They not only target bacteria that cause bad breath, but they also eliminate beneficial bacteria, drying out your mouth entirely, which over time, can make bad breath even worse.

Herbal rinses are a better option, particularly if they contain botanicals known to be effective against odor-causing bacteria. According to new research, licorice root may just be one of them.

Apart from being a potent solution for gum disease treatment and preventing tooth decay, this root offers a plethora of other healthcare benefits such as preventing oral cancer and candidiasis, aiding in better digestion, reducing acid reflux, helping with acne, etc.

Go on, what are you waiting for? Use licorice root-based products and make it a part of your daily oral hygiene routine, starting today!

While licorice root offers significant benefits for oral health, it also comes with potential side effects. A few are discussed below: Glycyrrhizin, its main bioactive ingredient, has been shown to cause an abnormal increase in the stress hormone, cortisol, which may cause imbalances in fluid and electrolyte levels, As a result, some products use deglycyrrhizinated licorice (DGL), with the glycyrrhizin removed.

This root is associated with several other side effects, including:

● High blood pressure
● Headaches
● Diarrhea
● Constipation
● Vomiting and fatigue
● Allergic reactions such as asthma
●Adverse drug reactions with blood thinners, blood pressure medications, statins, etc
● Risky for pregnancy as it causes a hormonal imbalance
