The short answer
Sensitivity near the gums often comes from exposed dentine after gum recession or enamel wear, but decay, a crack, or inflammation can produce similar short sharp pain.
What is the direct answer?
Gum-area sensitivity is often caused by exposed dentine. Recession uncovers the root surface, and enamel wear near the neck of the tooth can expose dentinal tubules that transmit cold or touch toward the pulp.
What does this question mean?
Other causes include early decay, a leaking filling, a cracked tooth, whitening products, an abrasion defect, or inflamed pulp. Brief pain after a trigger differs from lingering or spontaneous pain that can indicate deeper disease.
Use a soft brush with light pressure, avoid aggressive scrubbing, and reduce repeated exposure to very acidic foods and drinks. A desensitising toothpaste may help when used consistently, but it does not repair decay or a crack.
What can you do next?
Use a soft brush with light pressure, avoid aggressive scrubbing, and reduce repeated exposure to very acidic foods and drinks. A desensitising toothpaste may help when used consistently, but it does not repair decay or a crack.
Book a dental examination if sensitivity is new, worsening, localised to one tooth, lingers after cold, occurs without a trigger, or accompanies swelling, a broken filling, or pain on biting.
When should you seek dental care?
Book a dental examination if sensitivity is new, worsening, localised to one tooth, lingers after cold, occurs without a trigger, or accompanies swelling, a broken filling, or pain on biting.
Is the root exposed, or is there decay, a crack, or pulp inflammation? Would fluoride treatment, bonding, a filling, gum treatment, or another procedure address the cause?

Frequently asked questions
Why does one tooth react to cold?
A short response can come from exposed dentine, while lingering pain needs assessment.
