Final answer:
It is false that dental caries cannot be prevented or reduced; good oral hygiene, dietary changes, fluoridated water, and using xylitol-containing products can effectively prevent and manage tooth decay.
Step-by-step explanation:
The statement that dental caries cannot be prevented or reduced by changing lifestyle and dietary habits, applying therapeutic products, improving home care is false. Dental caries are caused by overgrowth of oral bacteria, such as Streptococcus and Actinomyces species, often due to insufficient dental hygiene. Regular dental cleanings, reducing sugar intake, and using fluoride treatments are effective ways to prevent or reduce dental caries.
Specifically, the ingestion of fluoridated water or application of fluoride treatment strengthens tooth minerals and reduces the occurrence of dental caries. Reducing consumption of acidic drinks and sugars can prevent microbial fermentation which leads to acid production that harms the teeth. Using sugarless gums or candies with sugar alcohols like xylitol can also reduce harmful acid production. Proper oral care, such as regular tooth brushing, flossing, and the use of antiseptic mouthwashes, can remove harmful microbes and protect against biofilm formation and microbial growth.
If dental caries develop, early treatment is crucial. Smaller areas of decay can be addressed with fillings, and more severe cases might require a root canal. Studies have shown that toothpastes containing xylitol are more effective at preventing dental caries than those with fluoride alone. Therefore, there is a combination of lifestyle, dietary changes, and dental treatments that can effectively prevent and manage dental caries.
