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.
Eruption of permanent teeth. Around the age of 6-7 years the first adult teeth begin to erupt in the mouth starting with the first permanent molars, also known as 6 year molars. They erupt behind the second primary molars (which will later be replaced by the second permanent premolars).
