What is typically the first sign of tooth squeeze during hyperbaric exposure?

1. Increased sensitivity

2. Throbbing pain

3. Dull ache

4. Sudden sharp pain

The correct answer is: Increased sensitivity

The first sign of tooth squeeze during hyperbaric exposure is typically increased sensitivity. This sensitivity occurs due to the pressure changes affecting the air cavities within the teeth and surrounding areas, leading to a heightened reaction to stimuli such as temperature changes or touch. As a diver descends, the increased pressure can cause the air trapped in dental work, such as fillings or crowns, to compress, resulting in discomfort or sensitivity. Increased sensitivity is often the precursor to more intense symptoms, such as throbbing or sharp pain, which may develop as the condition worsens if the pressure is not managed appropriately. Recognizing this early sign can help prevent further complications, as it indicates that a diver may need to ascend to alleviate the pressure or seek dental evaluation. Understanding this progression is vital for hyperbaric technologists to provide proper care and recommendations to divers experiencing symptoms related to tooth squeeze.
