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.
The eruption of teeth into the mouth occurs between 6 months and 30 months of age. The first teeth to erupt are usually the lower front teeth. The eruption chart shows the average age at which teeth emerge. This can vary considerably from child to child. See part 9 of this subject.
