Why Teeth Become Sensitive to Hot, Cold, or Sweet Foods

Cliniva Dental Clinic · DLF Phase 2, Gurugram · Updated 2026-08-26

If sipping tea, eating ice cream, or biting into a sweet feels like a sudden jolt in your teeth, you are dealing with tooth sensitivity, also called dentin hypersensitivity. It is one of the most common complaints we hear from patients across DLF Phase 2, Sector 25, and nearby parts of Gurugram. The good news is that sensitivity almost always has an identifiable cause, and most causes can be treated effectively.

What Causes Tooth Sensitivity

Underneath the hard enamel and root-covering cementum lies a softer layer called dentin, which contains tiny tubules connecting to the nerve inside the tooth. When enamel or cementum wears away or gums recede, these tubules get exposed. Hot, cold, sweet, or even acidic foods can then reach the nerve directly, causing that sharp, short-lived pain.

Common Reasons Enamel or Roots Get Exposed

• Worn enamel from brushing too hard, using a hard-bristled brush, or grinding teeth at night
• Gum recession due to gum disease or aggressive brushing, exposing the tooth root
• Tooth decay or cavities that create openings straight into the dentin
• Cracked or chipped teeth that let temperature and pressure reach the nerve
• Acidic foods and drinks such as citrus fruits, colas, and vinegar-based food that gradually erode enamel
• Recent dental work like fillings, whitening, or a deep cleaning, which can cause temporary sensitivity
• Old or leaking fillings that no longer seal the tooth properly

Why It Should Not Be Ignored

Occasional mild sensitivity is common and not always worrying. However, sensitivity that is getting worse, lasts longer than a few seconds, or is limited to one specific tooth often points to a cavity, a cracked filling, or an early gum problem. Left untreated, these issues can progress to more serious pain or infection. A dental check-up can quickly tell you whether it is a simple fix or something that needs deeper treatment.

How Cliniva Dental Clinic Diagnoses the Cause

At Cliniva Dental Clinic in DLF Phase 2, Gurugram, we start with a detailed oral examination and a discussion of your symptoms, including which foods trigger the pain and how long it lasts. We check for visible decay, gum recession, cracks, and worn areas, and take an X-ray if needed to look below the gum line or inside the tooth. This helps us pinpoint the exact cause instead of just masking the symptom.

Treatment Options We Offer

For Mild to Moderate Sensitivity

• Desensitising toothpaste and gels that block the tubules over regular use
• In-clinic fluoride varnish or desensitising agents applied directly to sensitive areas for faster relief
• Correcting brushing technique and switching to a soft-bristled brush to prevent further enamel loss

For Underlying Dental Problems

• Tooth-coloured fillings to seal cavities or replace old, leaking fillings
• Gum treatment to manage recession and protect exposed roots
• Dental bonding or a crown for teeth with cracks or significant wear
• A custom night guard if grinding is wearing down your enamel
• Root canal treatment in rare cases where the nerve is significantly affected and simpler treatments will not resolve the pain
