Cavities, also known as dental caries or tooth decay, are caused by bacterial infection that damages the hard tissues of the teeth. Once cavities occur, it is essential to intervene with dental treatment as soon as possible. Strictly speaking, cavities represent a bacterial infection caused by the failure to remove food residues timely after eating. Bacteria break down glucose, producing lactic acid, which causes demineralization of the teeth. Once cavities occur, it is crucial to undergo dental filling treatment promptly, commonly referred to as dental restoration. If the progression of decay is not promptly halted, it can lead to further complications over time, including pulpitis which causes toothache or night pain, pain during sleep intense enough to wake one from sleep, and in severe cases, facial swelling.
