Tooth Sensitivity: Causes and Treatments
Tooth Sensitivity: Causes and Treatments
That sudden sharp sting when you sip something cold or bite into something sweet isn't just a fleeting annoyance — it could be a sign of tooth sensitivity. Many people in Kolkata experience sensitive teeth, often ignoring it until the discomfort becomes constant. Understanding what triggers sensitivity and how to treat it early can prevent cavities, gum recession, and long-term dental issues.
Here’s a complete guide to what causes tooth sensitivity, treatments available, and how you can manage it at home.
What Is Tooth Sensitivity?
Tooth sensitivity occurs when the protective enamel wears down or gums recede, exposing the underlying dentin layer. Dentin contains small tubules that connect to nerves. When exposed, even everyday foods, temperature changes, or brushing can trigger sharp pain.
Common Causes of Tooth Sensitivity
1. Enamel Erosion
Acidic foods, soft drinks, poor oral hygiene, and aggressive brushing gradually wear down enamel, making teeth more sensitive.
2. Gum Recession
Receding gums expose the tooth root, which is not covered by enamel, making it extremely sensitive to hot, cold, or sweet substances.
3. Tooth Decay
Cavities expose deeper layers of the tooth, leading to pain when chewing or eating sugary foods.
4. Cracked or Fractured Teeth
A crack can open pathways directly to the nerve, causing discomfort especially when biting down.
5. Post-Dental Procedures
Treatments like fillings, whitening, or crown placement may cause temporary sensitivity that usually settles in a few days.
6. Teeth Grinding (Bruxism)
Grinding puts pressure on teeth and gradually wears down enamel, increasing sensitivity over time.
7. Acid Reflux or GERD
Acid flowing back into the mouth erodes enamel, leading to long-term sensitivity if untreated.
8. Habitual Use of Whitening Toothpaste
Some whitening products contain abrasive agents that can irritate tooth structure.
Symptoms You Should Watch For
- sudden sensitivity to hot or cold
- discomfort with sweet or acidic foods
- pain during brushing or flossing
- lingering sensation even after stimuli are removed
- visible enamel wear or gum recession
If symptoms persist for more than a week, dental evaluation is recommended.
Treatment Options for Tooth Sensitivity
1. Desensitizing Toothpaste
Special toothpaste blocks the nerve pathways and helps reduce pain over time. Use it consistently for better results.
2. Fluoride Varnish Application
Dentists apply fluoride gel or varnish to strengthen enamel and reduce responsiveness to stimuli.
3. Dental Bonding
If sensitivity is due to exposed roots, a resin coating can cover the area and protect the nerve.
4. Gum Grafting
In cases of severe gum recession, gum tissue is surgically placed to cover exposed roots.
5. Fillings or Crowns
When cavities or cracks are the cause, restorative treatments help seal and protect the tooth.
6. Root Canal Therapy
For extreme sensitivity resulting from nerve exposure or infection, a root canal provides long-term relief.
Home Remedies to Manage Sensitivity
- use a soft-bristled toothbrush
- avoid acidic drinks and sip with a straw
- switch to non-abrasive toothpaste
- rinse with warm salt water
- avoid brushing immediately after acidic foods
These practices offer relief, but they do not replace professional treatment.
When to Visit a Dentist
You should see a dentist immediately if sensitivity:
- worsens over time
- is accompanied by swelling or persistent pain
- occurs after injury or fracture
- interferes with everyday eating or drinking
Early diagnosis ensures simpler and less costly treatment.
Protecting Your Teeth from Sensitivity in the Future
- maintain oral hygiene with gentle brushing techniques
- avoid grinding or wear a night guard if needed
- go for regular dental check-ups
- limit sugary and acidic beverages
- get professional fluoride treatment every few months if advised
Prevention is easier than cure, especially when enamel loss is involved.
