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.
Could be your wisdom: Your second molars usually erupt around 12 years old. Since you are 18, these may be your wisdom teeth. Please see your dentist and ask him/her if these are your second or third molars and if they really are erupting towards your cheeks.
