Hypersensitivity Care Brand "Sensodyne" Prevents Tooth Sensitivity

Sensodyne, the No. 1 brand in the toothpaste market for 10 consecutive years*1, not only prevents tooth sensitivity but also helps prevent periodontal disease*2 and other issues. Hypersensitivity is a condition where external stimuli transmit through exposed dentinal tubules to the tooth's nerve, causing temporary pain. In Japan, approximately 60% of people experience tooth sensitivity, yet only about 15% are actively seeking care*3. It is important to seek appropriate care for tooth sensitivity, even if it is temporary.
