The answer is the nerve, or the pulpa of the tooth.
This is the part of the tooth that gives you the most pain when exposed. In most cases with things that are hot or more so with things that are cold, because your body is warm to begin with. The extream change in temperature and a thining layer of dentine due to cavities, receading gums and bone due to a build up of tarter and plac.
The dentinoenamel junction is the area where the hard enamel on the outside of the tooth meets the softer dentin on the inside. This junction is more sensitive because it lacks the protective enamel layer that covers the rest of the tooth, making it more susceptible to external stimuli like temperature changes and acids that can cause sensitivity and pain.
coronal pulp is the part of pulp that resides in the crown portion of the tooth,i.e. above the cementoenamel junction and radicular pulp is the part of pulp in the root portion.
CEJ is shorthand for "Cemento-Enamel-Junction. This is the point on a tooth that delineates the crown from the root of the tooth.
The section of the tooth where the anatomical crown meets the anatomical root is called the cementoenamel junction (CEJ). This junction marks the transition between the enamel covering the crown and the cementum covering the root.
root
The root .
The area of the tooth where the cementum meets the enamel is called the cementoenamel junction or CEJ for short.
yes. i have it in my mouth as we speak.
Most of the time they get sensitive because part of the tooth root is showing. Exposed root surface means that hot and cold feelings can reach the nerve of the tooth easier causing sensitivity from the nerve of the tooth. Brushing to hard, in the wrong direction or with whiting toothpaste can cause this sensitivity. This is not to be confused with pain when drinking or eating hot or cold things. Pain could indicate an infection in the nerve of a tooth. And needs to be treated with anti-biotics and root canal treatment or extraction.
anatomical crown
A Tooth AcheAnswerYou could have a sensitive tooth, cavity or possibly an abscess. I would make an appointment to see your dentist.
The Cementoenamel junction (CEJ) is located between the enamel and the cementum of your tooth.
