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.
Why can sensitivity near the gums cause short sharp pain?
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 other tooth problems can feel like gum sensitivity?
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.
How can you reduce irritation while protecting sensitive areas?
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 does sensitivity near one tooth need prompt dental review?
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.
When should I arrange an examination?
