[|Human|] Last month my dentist put in a crown, and since I have tasted and felt like there was dental cement stuck to the back of my tongue and my lips on that side of my face go numb feeling as if the novacaine is wearing off. Do I have nerve damage?
[|AI|]  Hello, I went through your query. There might be bit of cement stuck below your crown. You can go back to your dentist to get it removed easily. For the numbness of your lip, it is unlikely that you have a nerve damage, because nerve damage usually occurs after any kind of surgeries in the mouth. One possibility is Nickel allergy from the crown(if your crown is made of metal alloy), which usually can cause tingling sensation of tongue or lips. In any case, it is better to visit back your dentist to correct it. Hope you have benefited from the answer.
