No it won't .... but only if used as directed and intended (directions published on product label and website).Each of our products contain a safe amount of charcoal which makes the paste non-abrasive and gentle on teeth and gums. Other ingredients are added for its healing benefits.Our products are formulated with scientists at UPM and tested by dentists.ALL of our products contain Charcoal and VCO which are the key ingredients for brightening/whitening and detoxing.Over a year of RDA tests were done on various types of teeth to ensure that our formulation has the right ratio of ingredients (especially charcoal) that could remove the stubborn stains on the surface of our teeth without harming the enamel and results were evident.We also had an external 3rd party lab in Penang do an abrasion test against 2 other charcoal-based toothpaste products from US & UK. Our product was the least abrasive. We can share with you this lab's test results via email.However, it's important to note that charcoal is a super detoxifying agent and on its own is a strong harsh compound. Even though we use only a small percentage of it in our formulation and combine with other soothing agents like coconut oil, propolis, etc, it can still be strong for some teeth & gums conditions.Using more than recommended may result in side-effects we published on our website: Safety & Allergy Guidelines
