The scientists explained that about 3 out of every 4 people have teeth that are sensitive to hot, cold, sweet or sour foods and drinks. This sensitivity results when teeth enamel and the underlying dentin begin to wear down, stimulating the nerves within the teeth. This results in the painful sensation that many feel when eating certain foods. While sugar-free gums and toothpastes, such as Sensodyne, have been used to reduce tooth sensitivity, the scientists highlighted the need for simultaneous rebuilding of both the enamel and dentin to ensure less sensitivity. They began to look into dopamine, the sticky material that mussels use to adhere to surfaces. The scientists believed that this type of material would allow minerals necessary for renewal to adhere long enough to the dentin to improve the rebuilding process.
They attempted to demonstrate the possibility of using this material through multiple laboratory tests where they bathed human teeth with worn down enamel and dentin in a solution that contained the dopamine and essential minerals. Results showed that teeth that were placed in dopamine and mineral solution reformed dentin and enamel; however, the teeth kept in the solution containing only minerals resulted in the rebuilding of only the enamel. This shows the power of the dopamine and its adhesive effect of binding minerals for more effective rebuilding both enamel and dentin. Yun-Zhi Zhou believes that this sticky material found in mussels may be a promising means for preventing teeth sensitivity and may prove to be a universal technique that can be applied to millions worldwide.
As for some current, tried and true options, numerous toothpastes are available. Please talk with your dentist about which may be best for you. Desensitizing toothpaste works by blocking "transmission of sensation from the tooth surface to the nerve" They generally require consistent use for sensitivity to diminish. Some options Drs. Ali & Ali recommend are:
-ClinPro (available in-office)
-Sensodyne (over the counter)
