Preventive dentistry encompasses a range of practices aimed at maintaining oral health and preventing dental problems before they arise. Techniques such as oral examinations and low radiation digital imaging play a crucial role in early detection of cavities and other abnormalities, ensuring a holistic approach to dental care. Additionally, preventive measures like dental cleanings, the application of dental sealants, fluoride treatments, and the fabrication of custom oral appliances are integral to safeguarding teeth and gums against decay, disease, and injury. With the use of advanced technologies and materials, such as ultrasonic devices and safe resin for sealants, preventive dentistry offers comprehensive care focused on preserving dental health and preventing future complications.
