    Nevertheless, as a practical dentist, I like to recommend common use of hydroxyapatite toothpaste and never fluoridated toothpaste. Though extra individuals are turning into conscious of the elements they cook dinner with, they don’t examine for the elements of their toothpaste model. 

    Sadly, adults and kids are continuously uncovered to poisonous elements of their houses or locations they go to regularly. Some examples of dangerous metals and chemical substances are lead, mercury, arsenic, glyphosate, and chemical substances present in air air pollution.

    It’s practically inconceivable to regulate the extent of publicity to all of those poisonous elements. However on the subject of fluoride, it’s a no brainer: you may substitute fluoride in toothpaste with hydroxyapatite.

    You possibly can heal cavities and forestall new ones from forming by remineralizing your enamel. Hydroxyapatite is one very efficient method to try this.

    Hydroxyapatite performs simply in addition to fluoride, in some circumstances higher, with not one of the toxicity issues.
