Sometimes diseases of the jaw joint (temporomandibular joint), or spasms of the muscles used for chewing can cause toothache like symptoms.
The pain may be aggravated by chewing or by cold or heat. A thorough oral examination, which includes dental X ray, can help determine whether the toothache is coming from a tooth or jaw problem and the cause.
Common dental causes of toothaches include dental cavities, dental abscess, gum disease, irritation of the tooth root, cracked tooth syndrome, temporomandibular joint (TMJ) disorders, impaction, and eruption.
The teeth pain can also cause discomfort to other parts of the body. It can lead to headache, severe pain in neck and sometime pain in ear. It is a sign of damaged root canal and may need surgery. Such pains do not easily go away and need serious medical attention to cure the problem. The doctors usually prescribe medicines and suggest toothpaste to help patient find some relief. The patient should avoid eating hard foods and should consume large volume of water with high content of fluoride.
The most common cause of a toothache is a dental cavity. Dental cavities (caries) 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.
Root canal endodontic is a treatment used to repair and save a tooth that is badly decayed or becomes infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. Without treatment, the tissue surrounding the tooth will become infected and abscesses may form.
A root canal requires one or more office visits and can be performed by a dentist or endodontist. An endodontist is a dentist who specializes in the causes, diagnosis, prevention, and treatment of diseases and injuries of the human dental pulp or the nerve of the tooth. The choice of which type of dentist to use depends to some degree on the difficulty of the root canal procedure needed in your particular tooth and the general dentist's comfort level in working on your tooth. Your dentist will discuss who might be best suited to perform the work in your particular case.
