to anyone in the health care profession.?

The tongue is greatly supplied with nerves. Numbness of the tongue or certain areas of the tongue is very common for this reason. Saying that, there are so many numerous reasons for the tongue to become numb it may be hard to pinpoint the exact reasoning. Medications, and toxins can cause it. Infection, both bacterial, and yeast can cause it, and most commonly along with medications is vitamin deficiencies, in particular a deficiency of vitamin B12 will cause numbness in the tongue. When you talk tongue, you talk nerves, and when those nerves are disturbed numbness can be so very common, what is hard is determining what is causing it. I would see if you notice if anything triggers it, such as food, most commonly, fish given some fish do contain toxins, toothpastes, mouthwashes, anything that you introduce into your mouth. Try drinking bottled water instead of tap water to see if anything in your tap water is causing a reaction. You could be sure that your vitamin and mineral intake is adequate and you aren't suffering from any B12 deficiency. Sometimes dental fillings. and crowns can cause a reaction on the tongue, if you have any of those. Certain diseases, especially those concerning the brain, and nervous system can contribute to tongue numbness, even diabetes.Thyroid problems can also contribute to numbness in the tongue. You may have to keep an eye on any other symptoms you notice going on with your body that may tie the symptoms together. Whatever is going on, I hope you get to the bottom of it. Best wishes!
