What happens if the hair on your tongue comes off?

If the hair-like structures on your tongue, known as filiform papillae, come off, it may result in a temporary change in texture and sensation. This can occur due to irritation, excessive brushing, or certain medical conditions. While the loss of these papillae may cause discomfort or a smooth appearance on the tongue, they typically regenerate over time. If you experience persistent issues or discomfort, it's advisable to consult a healthcare professional.
