Products containing the ingredients hydrated silica , in particular, should be avoided when gum disease, tooth decay, sensitivity and receding gums are present. While these ingredients can remove tartar and make teeth whiter in appearance, they also may do harm to dental health by altering the acidic balance of the mouth, gums and tongue.
