Canker Sore Monthly Twice - Cause and Remedies

If You are getting periodical or monthly canker sore then you should be aware of it. You should check your health for vitamin C and Vitamin B12 Deficiency.

How ever Some Chemicals also responsible for this Canker sore. 
Sodium Lauryl Sulfate (SLS) is a chemical which may be reason for few peoples canker sore (Not for all).
SLS Mix Tooth paste


Sodium Lauryl Sulfate (SLS) is pretty harmless, though in shampoo it can cause irritation in a very small percentage of people.

Most of the Tooth paste having SLS Mix as Ingredients. Almost all the Tooth paste having Sodium Lauryl Sulfate as mix, but it may be allergic to some people , so it cause canker sore periodically.

The Natural / Ayurveda / Herbal tooth paste are mostly free from SLS mix.


To my knowledge all the shampoos and toothpastes contain this SLS. Though the manufacturers mark it as SLS-free, they have fewer harsh chemicals.

How to prevent Canker sore

Note down the period (Date , Month) whenever you get canker sore.

By the way you can come to know the date difference between canker sore. (say every 25 days)

Try to use an Alternate Herbal / Natural SLS free tooth paste.

Then wait till that canker period (say 25 days). 

If it doesn't produced the canker sore then you can continue to use any good SLS free toothpaste.

That's it.
