Hi Thanks for your query with Chat Doctor, cavities of teeth can be prevented with regular brushing with proper brushing technique in the morning and before going to sleep, rinsing the mouth after every meal, consumption of less sticky foods like sweets, taking sweets in between the meals, use of floss and regular use of mouthwashes (prolonged use is not recommended especially if it is chlorhexidine it may result in staining of teeth). By these methods you can reduce/prevent cavities. Hope this is helpful.
