Cavities are caused by bacteria in dental plaque breaking down carbohydrates, producing acids that erode tooth enamel.Signs include toothaches, sensitivity, visible holes or pits, and white, brown, or black staining on teeth.Key Prevention Strategies Optimal Oral Hygiene: Brush teeth at least twice a day with fluoride toothpaste and floss daily to remove plaque and food particles, which are primary causes of decay. Fluoride Use: Utilize fluoride toothpaste, mouth rinses, or professional fluoride treatments to strengthen enamel and prevent demineralization. Dietary Adjustments: Limit sugary and acidic foods and drinks, which feed decay-causing bacteria. Professional Care: Visit a dentist regularly for check-ups and cleanings to catch early signs of decay. Dental Sealants: Apply plastic coatings (sealants) to the chewing surfaces of back teeth (molars) to act as a barrier against plaque. Saliva Stimulation: Chew sugar-free gum to increase saliva flow, which helps neutralize harmful acids in the mouth.
