Hi, I have had an orange tongue for just over a week now. I recently saw the dentist right before this appeared. no matter how much i brush my tongue, scrub it even,  it comes right back, and doesnt ever fully go away. also, half my tongue has been numb since the dentist on account of them freezing it, and supposedly hitting a nerve. should I be worried?
Hello, You are describing paresthesia of the tongue. Usually this is a temporary situation and sensation will gradually return over time. How long ago did you have the injection? Has there been any change? Discoloration of the tongue can indicate some systemic changes. Please make sure that you have good nutrition with balanced vitamins. Iron intake is important. Take some vitamin B12. Make sure to keep well HY Chat Doctor.  Consider a visit to your physician to have a routine exam and lab blood tests. Consider any habits that may contribute to the color or food intake. Medications including recent antibiotic intake can cause discoloration. Oral yeast infections can cause discoloration as a result of a fungal infection. Try taking acidophilus, or you may require a prescription for Statin. Continue to practice good oral hygiene including tongue care. Be thorough, but not abrasive with your technique. Rinse with warm salt water. Monitor for any additional changes and discuss further with your dentist. Consider scheduling a visit with your dentist if the condition persists. A clinical exam would be helpful especially with your recent visit. The comparison from your recent visit would assist your diagnosis and treatment recommendation. Thank you for your inquiry. I hope you will feel better soon.
