My 7 year old son lost a tooth this winter. (His upper right tooth next to the front ones.) It has not come in yet. I know it can take a while, but the gum above where the tooth was has turned blue. No other part of his gums have turned blue. Should I be concerned? What could have caused this? ...Tammy in OK
Tammy, do not be alarmed at what is happening in your son's mouth. The blue that is in his mouth is the tooth erupting/coming in. It may be what is called an eruption cyst which will go away on its own when the tooth comes in. (if you notice one day that there is a lot of blood in your son's mouth, do not be alarmed because the cyst from the tooth erupting has burst) For some reason, these teeth, at times, do take a while to come in. I hope this has helped.
