Listed below are the most common reasons along with a brief explanation of each.Įxposed dentin can happen if tooth enamel or root is compromised or becomes exposed (see photo right). There is a multitude of reasons that can cause a tooth or teeth to become sensitive. Gum tissue is susceptible to injury if abraded (from brushing too hard) and inflammation in the presence of dental plaque and/or hard tartar. A healthy tooth root is buried in the jawbone and covered with gum tissue.Ĭementum is a thin, blanket-like layer that covers and protects the root surface. Root: The lower two-thirds portion of a tooth.
Nerve pain surpasses tooth sensitivity and often results in a dental emergency visit. The nerve sends messages to our brain and pain receptors letting us know when something’s not right. The nerve is found in the center most portion of the tooth called the pulp chamber. Exposed dentin will give rise to tooth sensitivity, especially when drinking cold beverages or eating cold foods. Dentinal tubules are microscopic pathways that extend from the dentin into the pulp chamber containing blood vessels and nerves. Dentin forms the major portion of a tooth and contains sensory nerve endings called dentinal tubules. Repeated exposures over time will result in tooth increased tooth sensitivity and possibly tooth decay.ĭentin is the layer of tooth under tooth enamel. Mechanical actions such as brushing too hard or grinding and/or clenching your teeth can weaken tooth enamel.ĭrinking acidic beverages such as pop and eating acid foods and candy will cause tooth enamel to demineralize (soften). Enamel is hard and serves to protect and insulate the internal tooth layers. Listed below are brief descriptions for how changes may impact your tooth anatomy.Įnamel is the outermost (white) layer of a tooth. How the anatomy of your tooth can impact tooth sensitivityĭetrimental changes in tooth anatomy can increase the likelihood that you’ll experience tooth sensitivity. Tooth sensitivity occurs when the root surface (dentin) of a tooth becomes exposed and reacts while eating, drinking, or while chewing or brushing our teeth.ĭentin (labeled dentine in photo right) contains fluid filled microscopic tubules (rods) that when exposed to a stimuli, trigger a response that we often interpret as painful zing.
It is estimated that 60-90% of US adults experience sensitive teeth (Source: Journal of Periodontology).
Sensitive teeth is an issue for many people, perhaps you?ĭo you ever experience a painful zing when drinking a cold beverage? How about when you brush your teeth? If so, you are not alone.
