One of the newer issues in the area of DUI is bleeding gums or Gingivitis and Periodontal Disease.
This issue arises when someone is arrested for DUI and he or she admits to having had two or three beers, but denies feeling the effects of the alcohol. But, the breath test reflects a 0.08% or greater blood alcohol concentration. How does this happen?
It’s been known for some time now that if someone was involved in a motor vehicle accident which resulted in blood in the mouth, that the blood being breathed in the breath testing machine will cause the machine to read at a higher level. Two things need to be addressed to understand the science involved in this issue. The first issue is how does breath alcohol testing work, and issue two, how does blood in the mouth or Gingivitis and Periodontal Disease affect a blood alcohol breath test?
