Tooth Sensitivity Treatment

Medically reviewed byDr. Saad Irfan— MDS, MSc, BDS· 27 July 2026

That sharp, sudden jolt from a sip of cold water or a spoon of ice cream is one of the most common dental complaints, and also one of the most misunderstood. Most people reach for a desensitizing toothpaste, and for some, that solves it. For others, it does not, because the toothpaste is treating a symptom while the actual cause — a cracked tooth, a receding gum line, decay starting between two teeth, or a leaking old filling — keeps getting worse underneath. At Dr. Saad Irfan Dentistry in DHA and Clifton, Karachi, tooth sensitivity is never treated as a single generic problem. It is diagnosed first, then matched to the treatment that actually addresses what is causing it. Dr. Saad Irfan holds an MDS in Restorative Dentistry and an MSc in Dental Materials from the University of Sheffield, UK, is PMDC registered, and has over 15 years of clinical experience. Diagnosing the exact cause of sensitivity is a restorative dentistry skill specifically — it requires understanding tooth structure, enamel wear patterns, and material behaviour at a level that goes beyond recommending a toothpaste brand. All three clinics — DHA Phase 5, DHA Phase 8, and Clifton Block 9 — are open 9AM to 11PM, 7 days a week, so a sensitivity assessment never has to wait weeks for an appointment slot.
