Bioengineered tooth "grows" in place to look and feel like real thing: scientists developed innovative new implant that "grows" into the gum and fuses with existing nerves to mimic a real tooth. It has been successfully trialed in rodents and was functioning like a normal tooth 6 weeks post-surgery.
