ToothSensitivityCouldBeaSignofDeeperProblems

If you wince in pain while eating or drinking something hot or cold, you’re not alone: tooth sensitivity afflicts one in three Americans. To understand what’s possibly going on, let’s look first at tooth anatomy.

Teeth are mainly composed of three layers: an outer protective enamel that covers the upper crown, a middle layer called dentin and an inner pulp. The dentin is composed of small tubules that transmit outer temperature and pressure sensations to nerves in the pulp.

The enamel serves as a “muffler,” damping sensations to protect the nerves from overload. In the root area, the gums and a thin material called cementum covering the roots also help muffle sensation.

But sometimes teeth can lose this muffling effect and the nerves encounter the full brunt of the sensations. The most common reason is gum recession, usually caused by periodontal (gum) disease. The gums have shrunk back or “receded,” and after a short while the cementum covering will also be lost, exposing the dentin in the root area.

Another problem is enamel erosion caused by mouth acid. Chronic high acidity, often caused by bacterial growth or acidic foods and beverages, can dissolve the enamel’s mineral content, causing decay and exposure as well of the underlying dentin.

To avoid future tooth sensitivity, it pays to prevent these two dental problems. The most important thing you can do is practice daily brushing and flossing to reduce bacterial plaque and see your dentist regularly for dental cleanings and checkups.

But if you’re already experiencing symptoms, you’ll first need an accurate diagnosis of the cause. If it’s related to gum disease, immediate treatment could help stop or even reverse any gum recession. To address enamel erosion, your dentist may be able to protect and strengthen your teeth with sealants and topical fluoride.

There are also things you and your dentist can do to reduce your symptoms. One is for you to use hygiene products with fluoride, which can take the edge off of sensitivity, or potassium, which helps reduce nerve activity. Your dentist can further reduce nerve sensitivity by blocking the tubules with sealants and bonding agents.

Tooth sensitivity is an irritating problem in itself; more importantly, though, it’s often a warning of something else seriously wrong that needs attention. If you’re feeling a little sensitive in the teeth, see your dentist as soon as possible.

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.

If you’re experiencing any kind of tooth pain, see us for an examination. We’ll determine the cause and initiate the appropriate treatment to regain your oral health.

DontPutOffGettingTreatmentforYourSensitiveTeeth

While out with friends one evening, you take a bite of ice cream. Suddenly, pain shoots through your teeth. It only lasts a second, but it's enough to ruin your good time.

This could be tooth sensitivity, a painful reaction to hot or cold foods. It often occurs when the enamel in prolonged contact with acid has eroded. Acid is a waste product of bacteria found in plaque, a thin film of food particles that builds up on tooth surfaces due to inadequate brushing and flossing. Enamel normally mutes temperature or pressure sensation to the underlying dentin layer and nerves. Loss of enamel exposes the dentin and nerves to the full brunt of these sensations.

Sensitivity can also happen if your gums have shrunk back (receded) and exposed dentin below the enamel. Although over-aggressive brushing can often cause it, gum recession also happens because of periodontal (gum) disease, a bacterial infection also arising from plaque.

The best way to avoid tooth sensitivity is to prevent enamel erosion or gum recession in the first place. Removing accumulated plaque through daily brushing and flossing is perhaps the most essential part of prevention, along with a nutritious diet low in sugar and regular dental cleanings and checkups.

It's also important to treat any dental disease that does occur despite your best hygiene efforts. Gum disease requires aggressive plaque removal, especially around the roots. While receded gum tissues often rebound after treatment, you may need gum grafting surgery to restore lost tissues if the gums have receded more deeply. For enamel erosion and any resulting decay you may need a filling, root canal treatment or a crown, depending on the depth and volume of structural damage.

While you're being treated you can also gain some relief from ongoing sensitivity by using a toothpaste with potassium nitrate or similar products designed to desensitize the dentin. Fluoride, a known enamel strengthener, has also been shown to reduce sensitivity. We can apply topical fluoride directly to tooth surfaces in the form of gels or varnishes.

Don't suffer through bouts of tooth sensitivity any more than you must. Visit us for a full exam and begin treatment to relieve you of the pain and stress.
