Toothpaste That Fixes Cavities As They Appear
By Roger Highfield - 24 Feb 2005
A toothpaste has been developed that can rapidly and seamlessly fix little cavities without need for drilling.
Dental paste of synthetic tooth enamel could revolutionize treatment of tiny early lesions, says the study published today in the journal Nature by Dr Kazue Yamagishi, of the FAP Dental Institute, Tokyo.
Tooth decay is normally treated by removal of the affected part, then filling the hole with a resin or metal alloy. This is less than ideal because a lot of healthy tooth must be removed to make the fillings stick.
Dr Yamagishi and colleagues developed a crystalline white paste of modified hydroxyapatite, which is chemically and structurally similar to natural enamel, and used it to repair early damage to a lower premolar tooth.
An electron microscope showed that the natural and artificial enamel became integrated as if they were one substance.
The paste seamlessly repaired early damage caused by acid forming bacteria.
New Toothpaste is Leaving Dentists Without Work
Kazue Yamagishi, a Japanese researcher has created a product that will revolutionize personal care, she has invented a toothpaste so good it will put dentists out of work.
This incredible toothpaste fills all the holes and cracks in the teeth, and restores the tooth enamel at the same time.
Holes and cracks in the teeth are the major reason for the need for dental work. Although brushing cleans your teeth, there has previously been no way to reverse the effects of damage to your teeth at home until now.
The toothpaste contains components which mimic tooth enamel, and build up where there are cracks in the tooth. It is similar in its form to regular toothpaste however, and so will be easily adopted by people in their own home.
The new formula was created by research with the chemical hydroxylapatit, also known as crystalline calcium phosphate, which makes up the main component of the tooth.
It works by causing a dilution of the acid on the surface of the teeth. After three minutes, the paste starts to crystallize and gets fastened to the structure of the natural enamel.
With the creation of this product, dentist visits could soon be a thing of the past.
