It might actually be a "Bohn's nodule". These are small, white bumps or cysts that develop on the gum ridge and are often mistaken for first teeth. At about 3months Gussy developed one that was funnily enough in line with where his K9 tooth would have erupted. Our CFHC nurse told me it was definitely a tooth, however said she'd not seen the first tooth appear in that spot before. So I went along for a couple of weeks thinking I had an "odd" child LOL. Then we had to see a Paed dentist on an unrelated topic and he had a really good look at it and said that it definitely wasn't a tooth, but rather a Bohn's nodule. Apparently it is exceptionally rare for anything other than the lower front incisors to erupt first. HTH K
