Tooth decay and cavities are the most common dental health problems experienced worldwide. However, a recent discovery shows that the rate of patients suffering from tooth decay and cavities has dramatically dropped, as a result of continuous intake and application of fluoride. Fluoride helps repair the initial stages of tooth decay even before the decay develops. In small and regulated amounts, it is as safe and effective as any other nutrients. Fluoride dietary supplements are also being developed to increase the strength of the enamel covering on the tooth prevent more serious oral health problems. If you wish to avail fluoride dietary supplements, it is important to first ask your dentist if supplements are safe and compatible to be included in your dietary needs.
