Green Tea Helps Prevent Halitosis

Thursday, October 15th, 2009

green tea

There are various food products that help control the bad breath smell that exists in people’s mouths.  As we have previously discussed, halitosis is primarily caused by the volatile sulfur compounds (also known as VSCs) like H2S and CH3SH produced in the mouth.  Bacteria in the mouth convert proteins into substances cysteine and methionine, and these are metabolized into VSCs.  In general, halitosis cures focus on controlling the number of “bad” bacteria in the mouth. 

There is a strong relationship between the natural antioxidants of green tea and good health, since it has been shown to have antimicrobial and deodorizing effects.  For instance, green tea can encourage strength, energy, and decrease a person’s chance for getting cancer.  Methyl mercaptan, as you may have previously read, is one of the foul-smelling volatile sulfur compounds that cause bad breath.  Along with other plant extracts, green tea extracts were analyzed with gas chromatography to see how strong their effects were on neutralizing the smell of methyl mercaptan. 

Research has shown that green tea extracts can deodorize multiple foul-smelling compounds in a person’s mouth, which can exist there from eating meat, smoking tobacco, and so on. 

The components and properties of green tea can help decrease the chances of someone having cavities and gum disease.  It helps mimize the effects of bleeding gums by helping the blood in the mouth clot. 

The deodorizing activity of green tea polyphenols is actually stronger than that of sodium copper chlorophyllin, a derivative of chlorophyll that is known to reduce odors.  Green tea also inhibits a bacteria called Streptococcus mutans, which is a major cause of tooth decay.  Green tea polyphenols also have a lot of positive effects for health issues outside of the oral cavity.

Green Tea Prevents Bad Breath

Friday, August 7th, 2009

Studies are showing that green tea can eliminate bad breath (halitosis). Thus far, green tea has been used for countless things:  preventing cancer, stroke, heart disease, weight loss, and so on.  Green tea has polyphenols, which are antioxidants that protect cells from damage.  The tea extracts help rid the body of disease-causing organisms since the antioxidants raise the body’s immune system. 

The malefic bacteria in our mouths can cause tooth decay and bad breath.  Pace University recently did a study on how effective green tea is at getting rid of bad breath.  In this research project, they mixed green tea with the bacteria that cause tooth decay and strep throat.  Results showed that green tea inhibited the bacterial growth by 30% and decreased the amount of bad breath-producing compounds.  Drinking green tea may also help one prevent getting sore throats and colds, since it helps fight the bacteria harboring in the throat. 

This same study also proved that green tea helps toothpaste and mouthwash fight viruses by eliminating bacteria.  Although, when researchers added green tea to the toothpaste, the bacteria were fairly inhibited, helping the toothpaste effectively fight off the oral viruses.  The malefic bacteria that multiply in the mouth create bad breath-causing compounds.  The tea inhibits these pathogens and helps destroy the foul-smelling compounds, thus putting a halt to bad breath.  Green tea also helps remove plague buildup within your gums and teeth.  Plague is another contributor to bad breath.

Tips to use green tea to combat bad breath:

1)  Drink plenty of green tea.
2)  Use it as a mouthwash.  Rinse your mouth with it before and after brushing your teeth. 
3)  Mix it with your toothpaste before toothbrushing.
 
So for now, skip conventional breath mints– sugar only will make halitosis worse.

Fight Off Tooth Decay and Bad Breath with Magnolia Bark Extract

Tuesday, June 16th, 2009

The magnolia is one of the oldest flowering tree types in the world.  Magnolia bark contains polyphenols, which have been used for centuries by Chinese and Japanese medicine.  Now, the magnolia bark chemicals have been proven to get rid of bad breath.  Research printed in ACS’ Journal of Agricultural and Food Chemistry shows that breath mints containing magnolia bark extract kill the majority of bacteria that cause tooth decay and bad breath within a half hour.  Magnolia bark extract significantly improves oral health around the world, and may be beneficial if used in chewing gum.

The mouth is an ideal environment for the bacteria that causes bad breath–especially four species of bacteria: Veilonella alcalescens, Fusobacterium nucleatum, Bacteroides melaninogenicus and Klebsiella pneumoniae.  These bacteria feed on food remains, dead cells, and other chemicals in the mouth, and in the process of their feeding, they release foul-smelling gases.  This putrefaction can lead to gum disease and tooth decay.

Regular chewing gum tends to only guard against these bacteria for a short period of time, and anti-bacterial products tend to have negative effects like tooth staining.  A team conducted a research project where they tested the power of a mint with and without the magnolia bark extract.  Without the extract, the mint destroyed just 3.6%  of the bacteria, and with the extract, 61% of the bacteria was killed. 

Furthermore, the extract has also been found to be useful for guarding against cavity-causing bacteria.
