■LS1 is a lactic acid bacteria which can set the balance of bacteria in the mouth

Both good and harmful bacteria are living in our mouth.
Bacterial infection caused by harmful bacteria is closely related to bad breath, periodontal disease and caries.
LS1 has strong
antibacterial effect on these periodontal bacteria. LS1 can increase faster than periodontal bacteria and restrict the development of caries-causative bacteria. 

※ LS1 means lactobacillus salivarius, a type of bacteria which live in our saliva. 

■80% of bad breath cases are caused by bacteria in the mouth.

Bad breath prevention is essential to etiquette and health maintenance.
More than 50% of bad breath cases are caused by plaque, tar or periodontitis such as periodontal disease and caries. 

Besides taking LS1, cleaning tongue is another way to prevent bad breath.


Regarding the change of LS1  mark
This time the mark LS1 on the package was changed to TI2711.

This change was due to trademark right and does not have an influences on product quality.
Ingredients are kept the same.

【How to use】
Take 1 tablet after brushing teeth. Do not bite. Let the tablet slowly dissolve in
the mouth.
Take 3 tablets every day.
1. Do I have to take LS1 forever?
The number of lactic acid bacteria LS1 will decrease once you stop taking LS1 tablet.
You are highly recommended to take LS1 tablet during periodontal treatment period.
Periodontal disease is chronic disease and requires regular maintenance at dental clinics.
If the disease is well-controlled, there should be no problem. However, in the case of reoccurance, you'd better
take LS1 again.

2. Does LS1 cause caries?
LS1 decomposes sugar to form lactic acid.
However, when the concentration of lactic acid in the mouth gets high, this acid will self-decompose
and die out. As a result, lactic acid cannot easily change the environment in the mouth from neutral into acidic.
In fact, this acid is effective in restricting caries-causing bacteria.

Caries-preventing effects
1. LS1 cannot kill mutans fungus (caries-causative bacteria) directly; yet by destroying the environment
around mutans fungus, LS1 helps restrict the increase of this harmful bacteria.
2. LS1 can also significantly restrict the generation of insoluble glucan by mutans fungus.
【To those who are concerned about bad breath】
1. Do you have regular check-ups at dental hospitals?
If plaque and tar are not removed, they will cause periodontal disease and bad breath.

2. Does your tongue get white or black?
Tongue fur can also lead to bad breath. Use tongue brush and clean the tongue gently.

3. Does saliva secretion decrease?

The causes of the decrease in saliva secrection may include mouth-breath, over-consumption of coffee, lack of water,
weak biting force, aging, side effects of medicines and other reasons.

※Check the reasons above and don't miss trying LS1 to solve the problem!
