Regrowing Natural Teeth: A Breakthrough in Dentistry

A groundbreaking discovery in dental science is set to revolutionize oral healthcare. Researchers in Japan have developed a potential treatment that could eliminate the need for dentures, dental implants, and other artificial teeth by enabling the natural regrowth of teeth. This is not science fiction but a reality backed by extensive research and successful clinical trials on animals.

Now, as human trials begin, key questions arise:

How does this tooth regrowth drug work?

What will the results be?

When will it be available for public use?

How much will it cost?

Let's explore this scientific breakthrough and its potential impact on the future of dentistry.

The Journey to a Revolutionary Discovery

The story dates back to 1991, when Dr. Karso Kakashi, a Japanese dentist, sought to determine whether natural teeth could be regrown. To advance his research, he pursued an MPhil in Molecular Biology and continued his studies in the USA, where he discovered that certain genes produce proteins that prevent tooth growth.

By 2005, Dr. Kakashi returned to Japan and conducted research at Kyoto University. His team made a significant discovery: when a specific gene was completely deactivated in mice, a protein called USAG-1 stopped functioning, allowing tooth regrowth. This led to the development of an antibody-based treatment that inhibits the USAG-1 protein, enabling teeth to grow naturally.

A Major Milestone in Dental Science

In 2018, the antibody treatment was successfully tested on mice, resulting in the natural regrowth of a lost tooth. By 2021, the research was published in the USA, marking the dawn of a new era in dental medicine. Since then, efforts have focused on adapting the medicine for human use.

Now, in 2024, human trials are set to begin. The first phase will focus on males aged 30 to 64 with missing teeth. The second phase will target children aged 2 to 6 who suffer from oligodontia, a condition where teeth fail to develop. In the future, this treatment could help individuals who have lost teeth due to decay, periodontal disease, trauma, or other factors.

How the Tooth Regrowth Treatment Works

Scientific studies reveal that, in addition to primary (baby) teeth and secondary (adult) teeth, humans also have a third set of tooth buds that remain dormant. This new tooth regrowth drug works by stimulating these buds, promoting natural tooth regeneration.

Advantages of This Breakthrough Therapy

Non-invasive: No need for stem cell surgery or genetic engineering.

Simple administration: Given as a single injection.

Potentially permanent: Could eliminate the need for dentures, bridges, and implants.

Regrows lost teeth naturally: Addresses both congenital tooth loss and acquired tooth loss.

Cost and Availability

The pharmaceutical company behind this research estimates the initial cost of the medication at around 1.5 million yen ($9,800 or 2.5 to 2.7 million Rupees). The treatment is expected to be commercially available by 2030.

A New Era in Dentistry

This pioneering innovation has the potential to redefine dental care, offering a natural, permanent solution for tooth loss. As human trials progress, the world eagerly awaits the results that could transform modern dentistry.
