Consistent high levels can indicate a problem in the home, as well as high indoor levels of spores relative to outdoor levels. Spores of Aspergillus and Penicillium are the same size and shape, so these are often reported as Penicillium/Aspergillus.
The front teeth are the first to erupt at around six to eight months; the back teeth erupt between 18 and 24 months. Teething, sometimes referred to as cutting teeth, occurs until all 20 primary teeth are in place. This is normally around two and a half years of age.
In general, the first baby teeth to erupt are usually the lower front teeth, and they come in between the ages of 6-10 months. Although all 20 primary teeth usually appear by age 3, the pace and order of their eruption varies from child to child.
