Veneers are thin shells, usually porcelain or composite, that cover the front surface of teeth to improve their appearance, fixing issues like stains, chips, gaps, or misalignment for a brighter, more uniform smile, with porcelain veneers being durable and stain-resistant, while composite are quicker and cheaper, with removable options also available, all offering cosmetic enhancement but requiring good oral health and proper care for longevity. best veneers in santhosapuram best veneers in madambakkam best veneers in vengaivasal best veneers in sembakkam
