Final answer:
The obturator pad should not be cleaned with harsh chemicals or solvents, nor should it be exposed to high water pressure.
Step-by-step explanation:
The obturator pad is commonly used in dentistry to provide support and protection to patients with oral defects or who have undergone surgery. It is important to follow proper cleaning procedures to maintain hygiene and prevent contamination. Avoid cleaning the obturator pad with harsh chemicals or solvents that can damage the material or cause skin irritation. Additionally, high water pressure can dislodge or damage the pad, so it is best to avoid exposing it to such conditions.
