The term 'tooth coating' can refer to two different solutions: ENAMEL and gearoil. ENAMEL is a type of paint or coating that is used to protect surfaces from damage and corrosion. It is often used on metal surfaces, such as cars, but it can also be used on teeth to protect them from decay. Gearoil is an oil-based lubricant that is used to reduce friction between moving parts in machinery. It is often used in the automotive industry to keep gears running smoothly. Both ENAMEL and gearoil are effective solutions for protecting teeth from damage and decay.
