What can help relieve sensitive teeth?
Tooth sensitivity can improve with desensitizing fluoride toothpaste, gentle brushing, and treatment of decay, wear, cracks, or exposed root surfaces.
Why does exposed dentine cause sharp tooth sensitivity?
The symptom is a short, sharp response from dentin when cold, hot, sweet, acidic, or touch stimuli reach fluid-filled tubules inside the tooth. Exposed dentin may follow gum recession, enamel wear, abrasion, erosion, a cavity, or a cracked tooth.
What can you do at home for sensitive teeth?
Use a soft brush, low pressure, and fluoride toothpaste made for sensitivity; spit after brushing rather than rinsing heavily. A dentist may apply fluoride varnish, a bonding material, or a restoration after checking the cause.
When should new or severe sensitivity be examined?
Book an examination when sensitivity is new, severe, localised to one tooth, lasts after the trigger is removed, or occurs with spontaneous pain. These features can indicate decay, pulp inflammation, or a crack rather than simple dentin sensitivity.
What could your dentist check behind tooth sensitivity?
Ask whether the pain is consistent with exposed dentin or with decay, a crack, or pulp disease. Ask which toothpaste, fluoride treatment, brushing method, or restoration is appropriate.
Frequently asked questions
Can home care replace a dental examination?
Home care can reduce irritation or symptoms temporarily, but it cannot diagnose or repair an underlying dental problem.
What happens at the appointment?
The dentist reviews your symptoms, examines the teeth and gums, and may use photographs or dental imaging before recommending treatment.
