Sensitive tooth repair
A sensitive tooth is repaired by treating its cause, such as exposed dentin, a cavity, a crack, gum recession, or an irritated pulp.
The short answer
A sensitive tooth is repaired by treating its cause, such as exposed dentin, a cavity, a crack, gum recession, or an irritated pulp. Sensitivity occurs when open dentinal tubules transmit cold, sweet, touch, or airflow toward the pulp. The same symptom can come from enamel wear, root exposure, caries, a fracture, or recent dental treatment.

Why do exposed dentinal tubules cause tooth sensitivity?

What can you do now to protect a sensitive tooth?
Use a soft brush and low-abrasion toothpaste, clean gently at the gumline, and avoid repeatedly testing the tooth with extreme temperatures. Clinical treatment may include fluoride or desensitizing agents, a bonded restoration, coverage of exposed root, or endodontic treatment.
When should localised tooth sensitivity be examined?
Book an examination when sensitivity is localized, worsening, spontaneous, prolonged after a stimulus, or associated with pain on biting. Swelling or a broken tooth warrants urgent care.
Which treatment will preserve the most healthy tooth tissue?
Ask what structure is exposed, whether an X-ray or vitality test is needed, and which treatment will preserve the most healthy tooth tissue.
Frequently asked questions
Can this be treated at home?
Home care may reduce irritation or symptoms, but it cannot replace treatment when a tooth, gum, restoration, or lesion has a structural cause.
What will the dentist examine?
Ask what structure is exposed, whether an X-ray or vitality test is needed, and which treatment will preserve the most healthy tooth tissue.
