What Are Nanoparticles and Their Role in Teeth Whitening?
Teeth whitening is a popular cosmetic dental procedure, and nanotechnology has introduced new methods to achieve brighter smiles. Nanoparticles such as titanium dioxide can be used in whitening agents to enhance their effectiveness. These particles can penetrate the enamel more efficiently, breaking down stains and discolorations at a molecular level without causing significant damage to the tooth structure.
