Symptoms and Signs of Teething

Doctor's Notes on Teething

Teething refers to the eruption of teeth in the gums, commonly referring to babies acquiring their primary teeth. Teething is a normal process that usually occurs between 6 and 24 months of age. However, babies may get their first tooth and begin teething anywhere from 4 to 10 months of age. A relatively rare condition, "natal" teeth, means there is the presence of a tooth at birth. This happens in about one out of every 2,000-3,000 live births.

The symptoms of teething, when present, usually begin a few days before eruption of a tooth. Symptoms and signs of teething include gum and jaw discomfort, a slightly swollen or red area at the site of the erupting tooth, and sometimes a blister over the involved area. Associated symptoms can include fussiness, increased drooling, mild rash around the mouth, putting hands in the mouth, and refusal of food.
