Explaining Teeth Sensitivity
The nerve of the tooth is contained within hollow chambers called root canals. The dentin, which is the layer of the tooth underneath the hard enamel, contains tiny fluid-filled tubes that transmit sensation to the nerve. When you eat or drink something cold or hot, the enamel normally acts as insulations. Anything that damages the enamel layer or exposes the dentin layer can lead to hypersensitivity.
Sensitivity is a common problem and is estimated to affect about 40 million Americans. You can reduce your risk of sensitivity by using soft-bristled toothbrushes and non-abrasive toothpaste and avoiding sour, sweet and acidic foods and drinks. Do not use hard-bristled toothbrushes, which can damage both teeth and gums, and avoid brushing too hard when you brush. Visit us regularly for cleanings and checkups.
If you already have sensitive teeth, try using a desensitizing toothpaste. This type of toothpaste has special ingredients that block the transmission of painful sensations. We can also help patients with sensitive teeth. Fluoride treatments can strengthen the enamel layer so that it can better insulate teeth while dental sealants can protect the roots and other vulnerable parts of teeth from damage.
Many cases of sensitivity are due to acid erosion or enamel wear, but in some cases, sensitive teeth can be a sign of a cavity, infection or other damage. Let us know about any sudden sensitivity or new symptoms. Call us today to schedule your next appointment with our dentist or to learn more about how you can protect your smile.
