inal answer:
Stannous Fluoride containing gels block tubules in teeth to prevent tooth sensitivity.
Step-by-step explanation:
Stannous Fluoride containing gels, such as Gel-Kam, block tubules in teeth, creating a protective barrier that helps prevent tooth sensitivity. The tubules in teeth are microscopic channels that connect the outer layer of the tooth (enamel) to the inner layer (dentin). When these tubules are exposed or open, it can lead to tooth sensitivity, where cold, hot, or sweet foods and beverages cause pain or discomfort. By blocking the tubules, Stannous Fluoride gels help reduce tooth sensitivity and provide relief.
