The irreversible loss of tooth structure due to non-carious processes is termed tooth surface loss. Tooth surface loss usually refers to several conditions including abrasion, attrition, abfraction, and erosion. Although the term tooth surface loss is less encouraged for use in clinical situations, tooth wear or erosive tooth wear are the terms more commonly used based on the understanding that severe tooth wear rarely happens exclusively due to an individual condition and might otherwise be contributory by acidic aetiology [Current preventive strategies against dental erosion include diet counselling, salivary glands stimulation to increase salivary flow, fluoride regimens (both, self and professionally applied), reducing intake of erosive beverages, and improving oral hygiene [Arginine (Arg), a semi-essential amino acid, is regarded as a prebiotic intervention for enhanced caries prevention when delivered with F [As a professionally-deliverable intervention, the caries-preventive potential of Arg-NaF varnish was explored by several studies eventually to conclude that incorporating 2% Arg in a 5% NaF varnish (Duraphat®) enhanced the anti-caries effect of Duraphat® varnish [
