A Thermoform Retainer, also known as an Essix Retainer or Clear Retainer, is a custom-made, transparent plastic appliance used after orthodontic treatment to maintain teeth in their corrected position. It is made by heat-molding (thermoforming) a thin plastic sheet over a dental cast of the patient’s teeth.

Topical Fluoride (also called Fluoride Gel) is a preventive dental agent applied directly to the tooth surface to help strengthen enamel, prevent tooth decay (dental caries), and reduce sensitivity. It is one of the most effective and widely used methods for protecting teeth in both children and adults.
