What is the reason those powerful toothpastes make gums slough?

Chemical irritation: These toothpastes may contain powerful chemicals or chemicals that you are sensitive to that would cause the outer surface of your gums to become so irritated that i can slough off . Stop using those products.

Too strong: Some toothpaste companies make stronger toothpaste to help remove stains and plaque better but some people might be allergic or sensitive to these products, stop its use but also consult a dentist to make sure it was the toothpaste that cause the gums to become sloughish.

Harsh chemicals.: Some of the toothpastes out there will, in some people, cause sloughing of the gum. If this happens to you, i would recommend a toothpaste without sodium laurel sulfate, the most common ingredient to cause side effects, although whitening toothpastes can do it because of the whitening ingredient as well!
