Tooth decay is also known as cavities or dental caries. The cavities can be a major problem for individuals no matter children, or even adults. Tooth decay is a location on a tooth where so much of the tooth's mineral content as been dissolved away that a defect cavity has formed. Teeth do have nerves in their centers and this tissue is soft, but the surface of a tooth where tooth decay begins is formed from types of tissues that are very high in mineral content. These tissues are called enamel and dentin. Two terms that is usually used to refer to tooth decay. The most common of these is the cavity which no doubt simply refers to the hole that often forms as a result of the tooth decay process. Another term that can be used interchangeably with tooth decay is the word caries. This is the term you will most frequently find used in dental literature.
Cavities first became an epidemic spread over a wide geographic region. Subsequently, tooth decay affected yet greater numbers of people with the widespread cultivation of the sugar beet.
The vast majority of the surface portion of a tooth that is visible is covered by enamel. We’ve probably heard that tooth enamel is the hardest tissue found in the human body. Enamel is more than 95% mineral in composition. Most of this mineral content is a compound called hydroxyapatite which is rich in calcium. Teeth are not solid enamel. Only the portion of a tooth that nature intended to lie at and above the gum line is covered by enamel. The bulk of a tooth, both its root and inner aspects, is composed of another calcified tissue called dentin. Dentin also contains the mineral hydroxyapatite, but to a lesser degree than enamel. Only about two thirds of the content of dentin is mineral so, relatively speaking, dentin is "softer" than enamel.

Tooth decay can, however, be prevented to a very great degree if the person understands and practices just a very few basic concepts. Dental treatments do not address the cause of tooth decay. This is why people keep returning to dentists with more and more cavities, no matter how many fillings or root canals they get. You could get lots of benefits if you cure the tooth decay. You could Limit or heal painful teeth or gums, prevent dental activities, avoid Novocain shots, reduce cavity rate, and avoid having your teeth drilled. To cure tooth decay would also lead to disseminating truthful information about healing tooth decay, empowering the individual to be more aware of their dental health, and promoting a safe and natural approach to heal tooth decay.
So, in conclusion, it cannot be said that we do not know the cause of tooth decay, and we cannot afford to sit in denial any longer. That’s why we should really take care of our teeth to avoid tooth decay. Yes you need to brush to maintain a healthy smile!
