Scientists never cease to amaze us with their new inventions. Dentures and implants may be a thing of the past as scientists can now grow new teeth in a patient's mouth.

Tooth loss is an issue that many people will face at some point in their lifetime. According to Underground Health Reporter, by the age of 75, around 26 percent of adults have lost nearly all of their permanent teeth.

And that's when dentures have their fair share of issues. But they come with a lot of burdens on their own— they make it difficult for the wearers to eat and speak normally. Dental implants can also fail and have no ability to "remodel" because the surrounding jaw bone changes with age.

Health issues associated with dental implants include nerve damage, infection at the implant site, sinus problems, and injury or damage to the surrounding structures.

According to Dentistry IQ:

"Despite being the preferred treatment for missing teeth today, dental implants can fail and have no ability to "remodel" with the surrounding jaw bone, which undergoes necessary and inevitable changes throughout a person's life."

PopularScience adds:

"Although dental implants are available, the healing process can take months on end, and implants that fail to align with the ever-growing jawbone tend to fall out. If only adult teeth could be regenerated, right?"

"According to a study published in the latest Journal of Dental Research, a new tissue regeneration technique may allow people to simply regrow a new set of pearly whites."

Luckily, scientists have come up with a more natural and comfortable solution to replace missing teeth by regrowing the tooth in the patient's mouth.

At his Tissue Engineering and Regenerative Medicine Laboratory, Dr. Jeremy Mao and his team are now able to induce the body's stem cells to develop a tooth based on a three-dimensional scaffold made of natural materials.

The results? A better-fit, natural tooth that grows in as little as nine weeks

According to Dr. Mao, the approach (which eliminates the need to grow teeth in a Petri dish) is a more cost-effective one "for patients who cannot afford or who aren't good candidates for dental implants."

As reported by Columbia University Medical Center, this approach to regrow teeth 'factor in the faster recovery time and the comparatively natural process of regrowth (as opposed to implantation), and you have a massively appealing dental treatment.'

A new tooth developed using stem cells can also adapt and move with the mouth, preventing discomfort and more severe issues later on. It's also healthier and more comfortable.

This gives the approach distinct advantages over implants and dentures, making it an excellent development in the field of dentistry.
