Yes, early-stage tooth decay (also called demineralization) can be reversed. At this stage, fluoride can help remineralize and strengthen the enamel, stopping further damage. However, once a cavity has formed and the enamel is broken, it cannot be reversed and needs professional treatment such as a filling or restoration by a dentist.
Tooth fillings usually last between 5 to 15 years, depending on the filling material, the tooth’s location, and your oral hygiene habits. Composite (tooth-colored) fillings typically last around 5 to 10 years, while amalgam or gold fillings can last 15 to 20 years or even longer with proper care.
White fillings are often preferred for their natural appearance, making them an excellent option for visible teeth. On the other hand, amalgam fillings offer exceptional durability and are well-suited for back teeth that experience heavy chewing forces.
Long-Term Results. Between these two treatments, professional teeth whitening tends to have more effective long-term results, especially when paired with proper care. While at-home kits can brighten your smile, the results may fade faster and the need for touch-ups could be more frequent.
Both treatments aim to restore tooth structure, function, and appearance. However, restorative treatment focuses on repairing damage to the outer surface of the tooth, while endodontic treatment addresses problems within the tooth’s internal structure, such as the pulp or root canals.
