What causes a cavity
Posted by healty family at 8:02 PMToothache because some things can be :
1. teeth holes
2 tooth infection
Why your teeth holes?
Blame plaque. It's sticky, slimy substance made up of from germs that cause tooth decay. Bacteria in your mouth make acids and when the plaque attached to the teeth, the acid can eat away at the outer layer of teeth, called the enamel (say: ih-na-mul).
If you do not go to the dentist, the acid can continue to make their way through email, and the inside of your teeth can begin to rot. If you have ever experienced toothache or heard an adult complain about one, it may be because there are cavities that reach all the way in the teeth, where the nerve endings.
Bacteria normally present in the mouth. Bacteria convert all foods - especially sugar and starch - into acids. Bacteria, acid, food debris, and saliva combine in the mouth to form a sticky substance called plaque attached to the teeth. This is most prominent in the back molars, just above the gum line on all teeth, and at the edge of the patch. Plaque is not removed from the teeth into tartar mineralizes. Plaque and tartar irritate the gums, causing gingivitis and ultimately periodontitis.
Plaque on the teeth begin to build within 20 minutes after eating (the time when most bacterial activity occurs). If this plaque is not removed thoroughly and routinely, tooth decay will not only begin, but flourish.
Acids in plaque dissolve the enamel surface of teeth and a hole in the tooth (cavity). Cavity is usually painless until they grow very large and affect nerves or cause tooth fracture. If not treated, tooth abscess can develop. Untreated tooth decay also damage the internal structure of the tooth (pulp) and ultimately lead to loss of teeth.
Carbohydrates (sugars and starches) increase the risk of tooth decay. Sticky foods are more dangerous than nonsticky food because they stay on the surface of the tooth. Frequent snacking increases the time that the acid in contact with the surface of the tooth.
to it make it a habit to brush your teeth regularly and always use Sensodyne toothpaste
