Theranostic Nanomaterials in Dentistry: Dual-Function Platforms for Diagnosis and Therapy

Smart nanomaterials are redefining the future of dental science by offering dynamic, stimuli-responsive solutions that adapt to the oral microenvironment. Engineered to react to biochemical and physical triggers such as pH variations, bacterial metabolites, and enzymatic activity, these materials facilitate localized, on-demand therapeutic responses. Their versatility spans across preventive and therapeutic domains—ranging from anti-microbial implant coatings and biofilm-disrupting agents to bioactive remineralizers and site-specific drug delivery vehicles. Innovations such as nanostructured scaffolds for guided tissue regeneration, theranostic platforms for oral malignancies, and smart analgesic systems illustrate the expanding frontier of nanotechnology in dentistry. While challenges persist in terms of regulatory compliance, long-term safety, and commercial translation, smart nanomaterials stand at the forefront of personalized, minimally invasive, and multifunctional dental care.
