Are some people more at risk for developing cavities?
Patients with reduced saliva flow from diseases such as Sjogren Syndrome, dysfunction of salivary glands, cancer chemotherapy or radiation, or smoke have the highest risk of developing cavities. Saliva is an essential component of fighting cavities because they can rinse away plaque, waste, and neutralize acid.
Patients with limited manual dexterity or have difficulty removing plaque from their teeth have a higher probability of seeing cavities formed on their teeth. Some people may have naturally low oral PH, which can increase the risk of cavities.
