What is the consequence of consuming sugars frequently?

• A. Increased saliva production
• B. Insufficient time for remineralization to occur
• C. Immediate enamel repair
• D. Decreased acid production

Answer: (B)

Frequent sugar consumption creates repeated acid challenges in the mouth. Bacteria fermenting these sugars produce acids that drop the pH in the plaque below the enamel’s critical level (about 5.5). When this happens, minerals are dissolved from the enamel in a process called demineralization. Saliva then buffers the acids and provides minerals to redeposit onto the enamel (remineralization). But remineralization takes time, and with frequent sugar intake there isn’t enough time between acid attacks for this repair to occur fully. The result is a net loss of minerals over time, increasing the risk of caries. The other options don’t fit because sugar intake does not cause increased or decreased acid production in the long term, nor does it produce immediate enamel repair.
