Tooth Sensitivity: Causes and Treatments Available in Clinic

Tooth sensitivity, what causes it and what treatments are available

Does it bother you to drink a cold beverage or eat something hot and you feel a sharp pain in one or more teeth? That could be tooth sensitivity, a frequent but treatable disorder if addressed properly. At Semedi Salud Málaga we evaluate the specific causes in each patient and apply effective clinical treatments to recover you from the discomfort. In this entry we will explain what tooth sensitivity is, what its usual causes are, how you can prevent it and the professional treatments available.


What is Tooth Sensitivity and how Does it Manifest

Definition and Physiological Mechanism

Tooth sensitivity (or dentin hypersensitivity) is a brief, sharp, and localized pain that occurs when the dentin is exposed and thermal, chemical, or tactile stimuli trigger a nerve response. The dentin has microscopic tubules that connect to the dental nerve, and when the protective layer of enamel or the gum disappears, those tubules allow the stimuli to activate the painful sensation.

Most Frequent Symptoms

  • Brief and intense pain when consuming cold, hot, sweet or acidic foods or drinks.
  • Discomfort when brushing, flossing or even when inhaling cold air.
  • Pain well localized in a specific area of the tooth, which subsides when the stimulus ceases.

Most Common Causes of Tooth Sensitivity

Enamel Wear and Acid Erosion

One of the most common causes is the thinning of the dental enamel, either by aggressive brushing, use of abrasive toothpastes or frequent consumption of acidic foods and beverages that erode the surface.

Gingival Recession and Root Exposure

When the gums recede, the root of the tooth (which has no enamel) is exposed. That part is more sensitive because it is protected only by cementum and dentin. This occurs in periodontal diseases, with aggressive brushing or aging.

Cavities, Defective Fillings or Dental Cracks

Carious lesions can expose the dentin, as well as old restorations with leaks or cracks in the tooth can leave vulnerable areas that cause sensitivity.

Bruxism or Wear by Friction

Grinding or clenching the teeth wears down the enamel and can cause the dentin to be exposed. It also generates microfractures that aggravate sensitivity.

Recent Dental Treatments (Whitenings, Deep Cleaning)

Some treatments such as tooth whitening can temporarily increase sensitivity by affecting the enamel or causing microlesions in the dental structure.


Prevention: Habits You Can Adopt

Gentle Brushing and Proper Techniques

Using a soft-bristled brush, making gentle movements and not brushing too hard helps protect the enamel and prevent gingival recessions.

Use of Desensitizing Toothpastes with Fluoride

Pastes specially formulated for sensitive teeth contain agents that help seal the dentinal tubules and reduce nerve stimulation.

Avoid Very Acidic Foods or Drinks

Reducing the consumption of citrus fruits, acidic soft drinks, intense juices and ultra-processed foods helps to preserve the enamel. Drinking water after these meals can neutralize the acidity.

Protect against Bruxism

If you grind your teeth, using a night splint can prevent additional wear and protect the enamel.

Periodic Dental Check-Ups

Visiting the dentist every six months allows detecting incipient lesions before they worsen and applying professional preventive measures.


Clinical Treatments Available at Semedi Salud

Professional Applications of Fluoride and Desensitizing Varnishes

The dentist can apply high concentration fluoride or special varnishes in the sensitive areas to strengthen the enamel and seal dentinal tubules.

Sealing of Exposed Root Surfaces

When there is notable gingival recession, coatings can be placed with biocompatible materials that cover the exposed root.

Restorations, Fillings and Repair of Fissures

If cavities, cracks or defective restorations are behind the sensitivity problem, they are repaired or replaced to eliminate the underlying cause.

Microabrasion, Resins or Desensitizing Adhesives

In mild to moderate cases, minimal techniques such as treatments with resins or special adhesives can be used to seal the exposed dentin.

Endodontic Treatments (Only if Necessary)

In the most severe cases where sensitivity appears due to persistent pulpal involvement, root canal therapy may be necessary to eliminate the source of pain.


Advantages of Adequate Treatment in Clinic

Fast and Lasting Pain Relief

An accurate diagnosis and appropriate treatment allow the discomfort to subside and not reappear if the correct habits are followed.

Protection of the Dental Structure

By treating the underlying cause, further damage is avoided and more healthy dental structure is preserved in the long term.

Improvement of the Quality of Life

Not depending on avoiding foods or drinks for fear of pain improves the daily experience and the enjoyment of food.

Prevention of Major Complications

If left untreated, sensitivity can evolve into deep cavities, pulpal damage or the need for more invasive treatments.


Tooth Sensitivity, Discomfort that You should not Normalize

Tooth sensitivity is a frequent discomfort, but not something you should accept as normal. Knowing its causes—enamel wear, gingival recession, cavities, bruxism—and adopting appropriate preventive habits can reduce its appearance. If you already experience pain, the professional treatments available (fluoride, varnishes, restorations, etc.) allow eliminating the cause and calming the discomfort efficiently.

In Semedi Salud, positioned in El Corte inglés de Málaga, we perform a personalized evaluation to identify the specific cause of your tooth sensitivity and apply the most appropriate treatment. Do not let a sensitive tooth limit your life. Whenever you want, develop the entry on “Psychotechnical recognition for drivers over 65 years: what you should know” with this same style.
