The first symptoms of tooth decay often manifest as increased sensitivity to cold, heat, or sweets, or even localized pain as the decay progresses. If not treated promptly, the decay can reach the dentin or even the dental pulp, causing intense pain and potentially requiring more invasive treatments such as deep cleaning, filling, or even root canal therapy.
Prevention remains the best way to fight tooth decay. Strict oral hygiene is essential: brushing teeth after each meal with a soft toothbrush and fluoride toothpaste, regular use of dental floss or interdental brushes to remove plaque between teeth, and regular visits to the dentist for professional check-ups and thorough cleaning.
