The vast majority of babies sprout their first teeth when they’re between 4 and 7 months of age. An early developer may get his first white cap as early as 3 months, while a late bloomer may have to wait until he’s a year old or more.
Some signs of teething are obvious; drooling, wakefulness, crankiness, crying, biting, chewing and tender gums are a few. Other signs of cutting teeth may be a little less obvious: she refuses food or may not be drinking milk; she may have a rash around the mouth; saliva irritates the delicate skin.
Some teeth may be more sensitive than others when they erupt. The first tooth to erupt may be the most sensitive. Sometimes, the larger molars cause more discomfort due to their larger surface area that can’t “slice” through the gum tissue as an erupting incisor is capable of doing.
