I am posting this because it may help some in this forum. I was looking for an answer to what I thought was an unusual symptom my 4 year old daughter was having ( itchy teeth). Specifically the bottom front two. I came upon this forum first then I came upon another one where many have this symptom right before or during a severe chest cold or pneumonia. While I realize some of you may be stimming, some may actually have an underlying medical issue. I hope this helps.
