The3TopCausesforToothSensitivity

Like other living tissue, your teeth can feel. Dentin, the layer below the enamel, houses fluid-filled conduits that transmit temperature or pressure sensations to a nerve network within the tooth’s inner pulp. It’s so effective that incoming sensations must be buffered — “toned down”— to avoid a painful overload of the nerves. The enamel above the gum line and a bone-like substance called cementum below help do this.

Unfortunately, if teeth lose this protection they can become hypersensitive. This can cause a flash of sharp pain while eating or drinking something cold or hot or just biting down.

There are a number of causes for tooth sensitivity, any of which can influence how we treat it. While you’ll need a dental exam to know for sure, your hypersensitivity will more than likely stem from one of these 3 problems.

Periodontal (gum) disease. This is an infection caused by bacterial plaque, a thin film of bacteria and food particles that accumulates on the teeth due to poor oral hygiene. The inflamed gum tissues weaken and detach from the teeth, causing them to shrink back or recede. This leaves the cementum unprotected, which easily erodes and exposes the dentin to acid and bacteria — and hypersensitivity. Clinically removing the plaque helps the affected gums heal. In extreme cases, the gums may need surgical grafting to regenerate.

Overaggressive brushing. While a lack of oral hygiene can contribute to gum recession, ironically too much hygiene — brushing too hard for too long — can damage your gums and cause them to recede. Brushing really doesn’t require a lot of elbow grease — a gentle scrubbing motion over all tooth surfaces is sufficient to remove plaque. Fine-tuning your brushing will help your gums to recover and heal.

Mouth acid. Although quite strong, enamel has one formidable enemy: acid, which can erode enamel and expose the dentin. Over-indulgence in acidic foods and beverages can make your mouth more acidic; more likely, though, bacterial plaque will again be the culprit, because bacteria excrete an acidic waste product. You can reduce mouth acid with daily brushing and flossing and consuming less acidic foods and beverages.

RootCanalTreatmentAlleviatesPainandSavesYourTooth

If you’re undergoing your first root canal treatment, it’s understandable if you’re apprehensive. So, let’s cut to the chase about your biggest fear: a root canal treatment doesn’t cause pain, it relieves it — and saves your tooth too.

You need this procedure because decay has spread deep into your tooth’s inner pulp. The infection has already attacked the nerves bundled within the pulp chamber, the source of the pain that led you to us in the first place.

The real concern, though, is the infection continuing to travel through the canals of the tooth root. If that happens, you’re in danger of not only losing the tooth, but also losing surrounding bone, adjacent teeth or damaging other important structures close by. Our goal is simple: remove the infected pulp tissue and seal the empty chamber and root canals from further infection with a special filling.

We begin by numbing the tooth with local anesthesia — you won’t feel anything but slight pressure as we work. After placing a dental dam — a thin sheet of rubber or vinyl — around the affected tooth to maintain a clean work area, we drill a small hole through the biting surface of a back tooth or in the rear surface of a front tooth. We’ll use this hole to access the pulp, where we’ll first remove all the dead and diseased tissue from the chamber. We’ll then disinfect the chamber and root canals with antiseptic and antibacterial solutions.

After some shaping, we’ll fill the chamber and canals, usually with gutta-percha that’s malleable when heated and can be compressed into and against the walls of the root canals to completely seal them. We’ll then seal the access hole.

You may have a few days of mild discomfort afterward, which can be managed generally with pain relievers like aspirin or ibuprofen. Later, we’ll permanently restore the tooth using filling to seal the root canal inside the tooth followed by a custom crown that’s fit over and bonded to the tooth. This will further minimize chances of a re-infection.

If we’ve recommended a root canal, then we think your tooth should be saved instead of extracted. The procedure will end the pain you’ve been suffering and give your tooth a new lease on life.
