At present，awareness of oral health care among older people in China is weak and the level of knowledge of oral care products is limited. Oral health is an important safeguard for the health of the whole body. It is important to raise the oral health literacy level of older people and help them develop the correct oral health behaviour. The correct use of oral care products such as toothbrushes，interdental brushes，fluoride toothpaste and denture cleaning products can effectively improve the oral health of the elderly and lay the foundation for a better quality of life.
