WhatsattheRootofToothSensitivity

In a healthy tooth, a coating of enamel protects the crown — the part above the gum line — and a layer of cementum protects the tooth root below the gum line. Enamel and cementum are inert (nonliving) substances that do not respond to stimuli such as heat or cold; however, dentin, the living tissue below them, does. Dentin contains numerous microscopic tubules that readily transmit stimuli toward the nerve-filled center of the tooth (pulp tissue). Loss of protective enamel or cementum leaves dentin exposed to all sorts of stimuli in the oral environment, which can trigger “dentinal hypersensitivity” — anything from a mild twinge to shooting pain.

Fortunately, there are many options for treating hypersensitivity. The key to selecting the most appropriate one(s) is determining the cause(s). Some of the more common reasons for sensitivity due to dentin exposure include:

  • Enamel erosion caused by an “acid attack” related to external (extrinsic) causes — i.e., consumption of acidic beverages/food — or internal causes — i.e., regurgitation of stomach acids due to gastroesophageal reflux disease [GERD] or the eating disorder bulimia
  • Using an overly abrasive brush or toothpaste, brushing incorrectly or too frequently, or brushing too soon after an “acid attack” — all of which can result in a loss of enamel
  • Tooth decay (dental caries or cavities)
  • Tooth fracture or chipping: tooth grinding (bruxism) is a common cause
  • Worn fillings
  • Gum recession, due to age or improper tooth brushing, that exposes the tooth root
  • Gum disease, which can result in gum recession

Sensitivity can also occur following a procedure like treating a cavity. Normally it subsides within a couple of weeks or so but if it continues there may be another underlying cause.

Whatever the source(s) of your discomfort, our office can get to the bottom of it and recommend an effective course of treatment that meets your personal needs!

DentalImplantsHelpedRockerStevenTylerGetBackonStageinRecordTime

Rock star Steven Tyler fell and broke his two front teeth while on tour with his band Aerosmith not long ago. But Tyler was back on stage the very next day, thanks to modern dental implant technology.

Dental implants are the most optimal tooth replacement system in use today. The reason we say “system” is because replacing teeth with implants involves two, or sometimes three, components: the implant itself, which replaces the root-part of the tooth; the dental crown that sits on top of it to replace the part of the tooth that's visible in the mouth; and a connecting piece placed in between the implant and crown, known as an abutment.

The implant itself, made of titanium, is placed directly into the jawbone with a minor surgical procedure. Titanium has the unique ability to fuse to bone, creating a very strong connection. An implant provides virtually the same function as a natural tooth root, including stabilizing the bone underneath and preventing its loss — something that naturally occurs when a tooth is lost.

This fusion process takes a period of weeks, which is why the implant needs time to heal before a permanent crown is attached. One reason for early implant failure is “loading” them with biting forces too soon. But in experienced hands, implants are extremely successful. Documented research and clinical studies indicate success rates of over 95% — which is higher than any other tooth replacement option. Once integrated and functional, implants can last a lifetime. That's why, though they are a bit more expensive initially than other tooth-replacement options, they are more cost-effective in the long term.

Of course, another advantage of implants is that they look and feel completely natural. Just ask Steven Tyler!
