How can elmex® Caries Protection toothpaste with Neo-Aminex™ technology help? elmex® Caries Protection with Neo-Aminex™ has been specially developed to protect against cavities. By quickly forming a homogeneous and durable protective layer, it both remineralizes the teeth and helps reduce future mineral loss. As a result, it strengthens enamel and makes teeth more resistant to caries. Not suitable for children under 7 years of age. For optimal oral care, start by using an interdental cleaning product, then brush with elmex® Caries Protection toothpaste using an elmex® Ultra Soft toothbrush, and finish with elmex® Caries Protection mouthwash.
