TL;DR: Severe tooth sensitivity to cold drinks and ice cream is often caused by receding gums that expose the vulnerable tooth root. While specialized toothpastes only mask the symptoms, soft-tissue grafting (gum grafting) performed by a periodontist permanently covers the root, stopping the sharp “zing” of pain and protecting the tooth from decay.
It is a beautiful June afternoon. You take a sip of iced tea or bite into a scoop of your favorite ice cream, and suddenly—ZING! A sharp, shooting pain rockets through your tooth.
For millions of adults, summer triggers a daily battle with temperature sensitivity. But that sharp wince isn’t just a sign that you need a different brand of toothpaste; it is often a giant red flag indicating a structural problem in your mouth: gum recession.
Here is why your teeth are protesting the summer heat, and how Dr. Barry Feldner can permanently turn off the pain.
Why Cold Hurts: The Anatomy of an Exposed Root
To understand the pain, you must look below the surface. The crown of your tooth (the part you see above the gum line) is covered in enamel—the hardest substance in the human body. Enamel acts as heavy armor, insulating the inner nerves of the tooth from hot and cold.
However, the root of your tooth does not have enamel. It is covered by a much softer, highly porous material called cementum.
When your gums recede due to aggressive brushing, genetics, or periodontal disease, they pull away and leave this porous root exposed. When an ice-cold drink hits that unprotected root, the temperature travels instantly through the microscopic pores directly to the tooth’s nerve, causing that characteristic shock of pain.
Why “Sensitive Toothpaste” Isn’t Enough
Many patients try to fix the problem in the pharmacy aisle. Desensitizing toothpastes work by temporarily clogging the microscopic pores on the exposed root to block the temperature from reaching the nerve.
However, this is only a temporary band-aid. It does not fix the fact that your structural barrier (the gum tissue) is missing. Leaving a root exposed leaves it highly vulnerable to rapid structural decay and cervical lesions.
The Permanent Solution: Soft-Tissue Grafting
The only way to truly cure root sensitivity is to replace the missing armor. As a Board-Certified Periodontist, Dr. Feldner uses an advanced microsurgical technique known as soft-tissue grafting (or gum grafting).
- How it works: We gently take a small amount of healthy tissue and graft it directly over the exposed roots.
- The Result: As it heals, this tissue integrates with your existing anatomy. It pulls the gum line back to its natural, youthful position, creating a thick Biological Seal.
By physically covering the root back up with your own healthy biology, the sensitivity to hot and cold is eliminated instantly.
Reclaim Your Summer
You shouldn’t have to drink your summer beverages through a straw or avoid ice cream with your family. If receding gums are causing you pain, we can rebuild your foundation.

Can receding gums cause tooth sensitivity?
- Yes. When gums recede, they expose the root of the tooth. Unlike the top of the tooth, the root is not protected by hard enamel. This allows hot and cold temperatures to reach the tooth’s nerve easily, causing sharp pain.
Can receding gums grow back to stop sensitivity?
- No, gum tissue cannot naturally grow back or regenerate on its own once it has receded. The only way to replace the lost tissue and permanently stop the sensitivity is through a clinical procedure like soft-tissue grafting.
How do you fix an exposed tooth root?
- An exposed tooth root is best fixed by a periodontist using soft-tissue grafting. This procedure takes healthy gum tissue and places it over the exposed root, integrating it with the existing gum line to protect the root from decay and eliminate temperature sensitivity.
