What do you do if you have an itchy tongue?

Because it has taste buds.

May be a pharmacist of your confidence can indicate to you a proper medicine.

When used properly, tongue scrapers can remove bacteria and dead cells from your tongue's surface. However, if you use a tongue cleaner too much or too aggressively, it can damage your taste buds.

No itchy is a sign of an allergic reaction, this could be due to the quality or lack of it in the jewellery in your tongue piercing.

Because they make your tongue twist and make you mess up what you're trying to say.
