Tooth Pain
Sensitive Teeth — Causes & Solutions
Sharp pain when eating or drinking cold foods? Tooth sensitivity always has a cause — and we can fix it.
One of the most common dental complaints, tooth sensitivity is your body's signal that the protective layers of your tooth have been compromised. We identify the cause and provide targeted treatment.

How Tooth Sensitivity Works
Why Your Teeth Hurt
Tooth sensitivity occurs when the protective layers of a tooth — the enamel on the crown or the cementum on the root — are compromised, exposing the underlying dentin. Dentin contains microscopic tubules that lead directly to the nerve.
When these tubules are exposed to temperature, acidity, or pressure, the nerve responds with a sharp, shooting pain. Understanding what is exposing the dentin is essential for choosing the right treatment.
Common CausesRoot Causes
What Causes Sensitive Teeth
Worn or Eroded Enamel
Enamel erosion from acidic foods, beverages, or aggressive brushing exposes the sensitive dentin layer beneath, causing sharp pain when exposed to cold, heat, or pressure.
At Vitality Health, we identify erosion patterns and address the underlying causes—recommending dietary changes, proper brushing technique, and protective measures.
Fluoride treatments strengthen the remaining enamel and help remineralize early erosion, while bonded restorations seal exposed dentin and restore protection.
Prevention is key: we counsel patients on acid management and proper oral hygiene to halt further erosion and protect their natural tooth structure.
Exposed Root Surfaces
Gum recession from periodontal disease, aggressive brushing, or natural aging exposes the root surface, which lacks enamel's protective barrier.
Root surfaces are naturally more sensitive because the dentin tubules are exposed directly to the oral environment, allowing stimulus to reach the nerve.
We treat exposed roots with gum grafting to restore gum coverage, fluoride varnish to seal the surface, or bonded restorations to restore comfort and protection.
Addressing the cause of recession—whether periodontal disease or brushing trauma—is essential to prevent further sensitivity and tooth loss.
Cavities & Tooth Decay
When cavity decay reaches the dentin (the layer beneath enamel), sensitivity and pain result from exposed tubules that transmit stimuli to the nerve.
As decay deepens toward the pulp, pain becomes more severe and constant, often causing throbbing or aching sensations.
Small cavities can be painless initially, which is why regular exams are essential to catch decay before it causes pain and requires more extensive treatment.
Prompt filling of early cavities prevents progression to nerve inflammation requiring root canal therapy.

Sensitive Teeth FAQs
Answers to common questions about tooth sensitivity
Not usually. Sensitivity tends to worsen without treatment because the underlying cause is often progressive. Professional evaluation and treatment are recommended.
Desensitising toothpaste helps with minor sensitivity from enamel wear, but it cannot address cavities, gum recession, or failing restorations. These require professional treatment.
Yes. Use a soft-bristled toothbrush, brush gently, avoid acidic foods and drinks, address grinding with a night guard, and maintain regular dental exams.
Simple treatments like fluoride application provide relief quickly. Restorative treatments like fillings or bonding are completed in one or two appointments.
