Kazue Yamagashi is a Japanese scientist who has recently made an invention that will change dentistry forever. Yamagashi designed a powerful toothpaste that will not only clean your teeth – it will fill all the cracks in them and restore their protective coating (enamel). The paste has the same composition as the tooth enamel although in liquid form which makes it easy to apply on a toothbrush and use. Before going into any details, let’s talk about tooth decay first.
What Is Tooth Decay?
Our teeth have 4 layers – enamel on the surface, which is a mineralized shell that protects the teeth; dentin underneath it, which is another protective layer; pulp in the center of a tooth, which contains nerve endings and blood vessels and cementum underneath it all which is a mineralized tissue. When we eat unhealthy acidic foods, the acids can “chew” right through the protective layer and affect the dentin and pulp, resulting in tooth decay and cavities.
Main Symptoms Of Tooth Decay
Toothache and pain when drinking something cold or hot are the main symptoms of tooth decay. You may also experience visible spots on the teeth. The usual treatment for tooth decay and cavities is dental filling, but Yamagashi’s toothpaste is a great non-invasive option that will repair your teeth without destroying their protective layers.
How Does It Work?
The paste is even better than tooth filling as it can fill the cavity without the drilling part. This saves time and is painless and could become replace the drilling in the future. Once you apply the paste on your teeth, it dilutes the acid on the teeth surface and start crystallizing in 3 minutes. After this, it bonds to the enamel on your teeth and effectively closes the cavity.
Although it can be used at home, it’s best to let a dentist handle the procedure due to its acidity. The paste contains a high level of hydrogen peroxide which may inflame your gums and cause a few problems. Kazue and her team are hoping that the paste will be available to the public soon. She also hopes that it will become the preferred option to fillings which are pretty invasive and painful.
