Fluoride plays a crucial role in dental health through three key actions. Firstly, it significantly strengthens tooth enamel, acting as a barrier against tooth decay. Secondly, fluoride aids in the remineralization of teeth at the initial stages of decay, helping to halt further damage. Lastly, fluoride application can effectively desensitize areas prone to sensitivity, providing relief. At our clinic, we utilize a paint-on fluoride varnish, which has proven to be more effective in delivering fluoride directly to the enamel compared to fluoride rinses or trays filled with fluoride gel.
