Tooth sensitivity is pain caused when the healthy insulating structures that cover and protect the nerves of teeth are damaged. These include enamel and cementum. The dentin beneath enamel and cementum has microscopic tubes that connect to the tooth nerves when they are exposed, such as by gum recession or brushing too hard.

Using desensitizing toothpastes, and fluoridated mouthwashes, is the best first step to combat sensitive teeth. These products help seal the small tubes inside your tooth where nerves travel, preventing them from feeling pain when eating cold or hot foods.
Sometimes sensitivity is caused by teeth that have been exposed, either due to wear from clenching or grinding your teeth, or because of a dental procedure that has worn away some enamel. In these cases, your dentist may recommend a fluoride treatment that helps to remineralize the enamel and reduce sensitivity.
Tooth sensitivity is also sometimes the result of acidic foods, which can wear down your enamel, leaving the dentin, or middle layer of your teeth, exposed. Your dentist can recommend ways to decrease your sensitivity from eating certain foods, such as using a fluoride rinse, or a mouthwash that contains an anti-acidic solution.
Teeth sensitivity can also be a sign of an infection, which your dentist will assess with x-rays and gum measurements to determine whether there is any advancing dental disease present. Your dentist will then recommend treatment to address the underlying cause of your sensitive teeth. For example, if your sensitivity is due to teeth grinding or exposure of the root surfaces, your dentist may recommend a root canal, a filling, composite bonding, or other reparative treatments.
Bonding
Tooth sensitivity is often caused by the exposure of the inner dentin to hot, cold, acidic or sticky foods. Dentin is less dense than enamel and cementum and has microscopic tubules which are filled with nerve endings. When these tubes become irritated by pressure changes or by the presence of highly acidic, spicy or sugary foods, painful sensations are felt as if your teeth were being drilled.
Brushing too hard, using an abrasive toothpaste, grinding your teeth or receding gums can all lead to tooth sensitivity by wearing away the enamel and gum tissue which exposes the dentin. Using desensitizing toothpaste can help but only provides temporary relief.
Bonding is a treatment option that can provide permanent relief for tooth sensitivity by applying a thin layer of tooth-colored composite resin to the exposed root surface. This material is then hardened with a special light. Bonding is ideal for small cosmetic changes, correcting a chipped tooth or filling a deep cavity.
A dental bonding procedure requires no anesthesia and can be performed at the time of a cleaning or during a regular visit to the dentist. Unlike dental fillings, bonding materials do not have the strength to resist biting or chewing. It is therefore important to avoid biting down on hard objects such as fingernails, pens or ice or using your bonded teeth to open packages.
Fillings
Does a sip of ice cream or brushing your teeth make you wince? Sensitive teeth can occur when the outside layer of your tooth that protects against hot or cold temperatures, pressure and sugary foods is worn away, or a crack in your tooth is exposed. If this happens, visit your dentist to discuss sensitivity treatment options.
When you have sensitive teeth, nerves in your dentine can be stimulated and trigger pain. A tooth filling can help relieve this sensitivity by covering the exposed dentine and creating a barrier to stop these stimuli from reaching the nerves.
A composite resin can be bonded to the surface of your tooth to cover any cracks, chips, or gaps. The procedure is quick and comfortable. Before bonding the tooth, Dr. Jobst will prepare the surface with an etching compound to open natural microscopic pores in the enamel for a strong bond. He will then color-match the resin and artfully mold it to the area of the tooth.
If you are experiencing sensitivity after a dental filling, the sensation is typically temporary and will go away on its own within a few days or weeks. This sensitivity is caused by minor nerve irritation or inflammation due to the drilling, and will improve with time. If the sensitivity persists, call our office for further evaluation.
Root Canal
The root canal is a treatment used to remove the damaged nerves in a tooth that have become irreversibly infected. The procedure can help relieve sensitivity that develops after eating or drinking hot or cold foods and drinks.
Tooth sensitivity is often caused by the loss of enamel and cementum on the tops of teeth or exposure of dentin after gum recession. The dentin contains microscopic tubules that allow heat, cold, sticky, acidic or sugary foods to reach the nerves in the tooth and cause pain. Desensitizing toothpaste is a simple, inexpensive treatment that contains ingredients that block transmission of sensation from the teeth to the nerves.
It is also common for teeth to feel sensitive a few days after root canal therapy due to the body’s natural inflammatory mediators. However, if the pain and sensitivity persist, the patient should visit an endodontist for evaluation.
If a patient experiences pain in the tooth while chewing, it is an indication that there is a fracture or other serious problem with the tooth. Your dentist will evaluate the problem and recommend the necessary treatments. In some cases, a dental crown may be recommended to repair the damaged tooth and restore its function and appearance. A surgical gum graft is another option to protect the exposed roots and reduce sensitivity.
