• Enamel – when bacteria produce lactic acid, it erodes the tooth enamel and this causes the enamel to lose minerals and become more dangerous until it reaches the core of the tooth.
• Secondary – this type of decay occurs when improvements by the dentist do not work on the teeth, and with a small correction the decay will go away.
• Severe – when the growth of caries in the teeth is rapid and extensive, it is classified as acute caries, is usually light brown or gray in color, and can affect multiple teeth at the same time.
• Stopped caries – when caries stops growing further in the tooth, it is called stopped caries. It may occur when the beginning of caries is stopped by taking the necessary measures to take care of the health of the mouth and teeth.
• Early Childhood – Babies and young children tend to fall asleep during or immediately after feeding milk. Leftover milk in the mouth can feed bacteria and cause cavities, so as soon as the first teeth appear, avoid putting your baby to bed when there is still milk left in his mouth.
