i don't believe there are any environmental risks to living above the dentist office assuming their x-ray is properly shielded (you would need to investigate this with the dentist or landlord but it is an important bit of information that you deserve) and their ventilation system is separate. while stray x-rays can be a problem most dental films are less-penetrating (of walls) and are usually quite focused downward toward the teeth. the only other risk that i can see is the sound of the drill and screaming downstairs and perhaps that disturbing "dental office" smell!
is it safe for a child to live in an apartment that is located directly over a dentist's office? . i have a 4-year-old daughter. we are losing the lease on our current apartment and have found a very nice apartment to move into that is on the 2nd floor of a building which has a dentist office on the ground floor. we will be directly above the dentist. does such a living arrangement pose any risk to my child what with the dental office containing an x-ray machine?
