Dentures or Dental Devices and Mouth Alcohol

The breath test machines used in Florida, the Intoxilyzer 8000, can give a subject an inflated reading if the person has dentures, an orthodontic plate, fillings, or other dental devices or dental work that can trap mouth alcohol.

Although the machine is designed to distinguish between mouth alcohol and breath alcohol from the deep lungs, the timing of the last drink and the presence of dental work can greatly affect the breath test reading.

Florida law does not require the removal of dentures, an orthodontic plate, or other dental devices nor does the law impose an obligation on the officer to inquire about the use of dentures prior to or during the administration of alcohol tests.

In other states, such as Nevada, the breath test operator is trained to ask the subject to removable dental work including dentures or partial dentures before beginning the observation period. In certain cases, the machine may actually detect the presence of mouth alcohol which invalidates the result. However, in other cases, the machine may not detect mouth alcohol leading to an inflated breath test reading.

Slope Detectors on the Intoxilyzer 8000

The manufacturer of the Intoxilyzer 8000 has equipped the instrument with a "slope detectors" to help identify mouth alcohol. During a breath test, the Intoxilyzer 8000 was designed to measure alcohol content continuously over a period of time.

When mouth alcohol is present, it creates a different pattern than a normal breath sample. If there is no mouth alcohol in the sample, the Intoxilyzer 8000 was designed to return a continuous, though not linear, rise in breath alcohol level until it reaches a plateau.

When mouth alcohol is present, the Intoxilyzer 8000 was designed to register an error message showing that slope was not level and experienced a sudden drop. Although the slope detector on the Intoxilyzer 8000 is useful, it is not perfect.
