As in sterile? No way. The mouth is just too perfect an environment for microbe growth. It is warm, dark, moist, and it has a good food supply.
You can reduce the bacterial load on the tongue through effective oral hygiene practices and perhaps through the use of antimicrobial rinses, but it is highly unlikely you could ever get a tongue to be completely free of bacteria.
The only exception is a newborn infant before their first meal. Their mouths are usually germ free. Once milk or formula is introduced, the bacteria are present and multiplying.
On the upside, the normal flora (microbes) that inhabit a 'clean' mouth are not harmful.

The tongue is derived from the ectoderm germ layer during early embryonic development.

Germ Free Adolescents was created in 1978-11.
A germ-free state refers to an environment, object, or organism that is completely free of germs or microorganisms, including bacteria, viruses, and fungi. Achieving a germ-free state typically requires meticulous cleaning, sterilization, and maintenance of hygiene practices to prevent the introduction of any pathogens. Germ-free states are often seen in laboratory settings for research purposes or in certain medical procedures.
There is only one reason that anyone would wear a tongue ring, and that is a lapse in judgement. Of course people are free to do this, but it can lead to permanent scar tissue in the tongue, resulting in possible speech difficulties.

The study of life under germ-free conditions is called gnotobiology. It involves studying organisms in a controlled environment free of all microorganisms.
