Answer:

Hi Shorty20. I am not a dentist. I have given you information here that I found on the Net. After you read this, 'Google' dental cavities and see what information you have to work with.

The most common cause of a toothache is a dental cavity. Dental cavities are holes in the two outer layers of a tooth called the enamel and the dentin. The enamel is the outermost white hard surface and the dentin is the yellow layer just beneath the enamel. Both layers serve to protect the inner living tooth tissue called the pulp, where blood vessels and nerves reside. Certain bacteria in the mouth convert simple sugars into acid. The acid softens and (along with saliva) dissolves the enamel and dentin, creating cavities. Small shallow cavities may not cause pain and may be unnoticed by the patient. The larger deeper cavities can collect food debris. The inner living pulp of the affected tooth can become irritated by bacterial toxins or by foods that are cold, hot, sour, or sweet-causing toothache. Toothache from these larger cavities is the most common reason for visits to dentists.
