Tooth decay is the most common dental disease, occurring when bacteria in plaque convert sugars from food into acid, gradually destroying enamel and dentin.
Key risk factors include poor oral hygiene, high sugar intake, insufficient fluoride, and dry mouth from reduced saliva flow. If left untreated, decay can progress deep into the tooth pulp, causing severe pain and potentially requiring extraction.
To prevent decay effectively, brush regularly with fluoride toothpaste, floss daily, limit sugary foods, and get a dental check-up every 6 months to catch early signs of decay.
