Tooth Sensitivity Causes and Treatment at Miami Village Dental

What Is Tooth Sensitivity and Why Does It Happen?

Tooth sensitivity is a sharp, temporary pain that occurs when the dentine layer of a tooth becomes exposed to temperature or chemical triggers. Dentists refer to this condition as dentine hypersensitivity. According to the Australian Dental Association, approximately 1 in 3 Australian adults experience tooth sensitivity.

Tooth anatomy explains why this pain occurs. The crown of a healthy tooth features a hard outer shell called enamel. Enamel protects the underlying dentine. Dentine contains thousands of microscopic tubules that lead directly to the tooth nerve, known as the pulp. When the enamel wears away or the gums recede, the dentine loses its protective shield. Hot, cold, sweet, or acidic substances enter these exposed tubules. The substances stimulate the nerve inside the tooth. This stimulation causes the sudden, sharp pain associated with sensitive teeth.

What Are the 7 Most Common Causes of Sensitive Teeth?

Sensitive teeth causes vary from lifestyle habits to structural tooth damage. Understanding why your teeth are sensitive requires examining 7 common triggers.

1. Enamel Erosion from Acidic Foods and Drinks: Acidic items dissolve tooth enamel over time. Frequent consumption of citrus fruits, soft drinks, wine, and vinegar wears down the protective layer. Thinner enamel allows temperature changes to reach the dentine.
2. Gum Recession Exposing Tooth Roots: Periodontal disease or aggressive brushing causes gums to pull away from the teeth. This process exposes the tooth roots. Roots lack an enamel coating. Cementum covers the root surface, but this material is softer than enamel and wears away quickly. For more information, read our page on gum recession.
3. Tooth Decay and Cavities: Bacteria produce acid that destroys enamel and dentine. A cavity creates a direct pathway for stimuli to reach the nerve. Treating decay with tooth-coloured fillings stops this sensitivity.
4. Cracked or Chipped Teeth: Physical damage creates fractures in the enamel. Bacteria and temperature changes enter these microfractures. Learn about diagnosing a cracked tooth to stop the pain.
5. Aggressive Brushing: Using a hard-bristled toothbrush wears away the enamel surface. Scrubbing teeth horizontally pushes the gums away from the tooth neck. This mechanical wear exposes the dentine.
6. Teeth Grinding (Bruxism): Clenching and grinding exert massive pressure on teeth. This force creates microfractures in the enamel and stresses the nerve. Wearing splints for teeth grinding prevents this damage.
7. Recent Dental Procedures: Dental treatments irritate the tooth nerve temporarily. Procedures like fillings, crowns, or professional teeth whitening cause inflammation in the pulp. This sensitivity after treatment is temporary and resolves within 2 to 4 weeks.

What Are the Symptoms of Tooth Sensitivity?

The symptoms of tooth sensitivity include sharp, sudden pain triggered by specific environmental or dietary factors. The pain is brief but intense. Patients experiencing sudden tooth sensitivity notice 6 specific triggers.

1. Tooth Sensitivity to Hot: Consuming hot food or drinks like coffee, tea, or soup triggers an immediate sharp pain. The heat expands the fluid inside the dentine tubules, stimulating the nerve.
2. Tooth Sensitivity to Cold: Cold food, icy drinks, or breathing in cold winter air causes sudden discomfort. The cold temperature contracts the fluid inside the tubules. This contraction triggers pain signals.
3. Reaction to Sweet Foods: Sugary and acidic foods like lollies, chocolate, or honey cause pain. Sugar changes the fluid dynamics in the dentine tubules, stimulating the nerve endings.
4. Discomfort During Brushing: Brushing with cold tap water causes a sharp, radiating pain. The cold water hits the exposed dentine directly during the brushing motion.
5. Brief Resolving Pain: Sensitivity pain remains short. The pain resolves quickly once the patient removes the trigger. Pain lasting longer than 30 seconds indicates a more severe issue.
6. Localised Pain: Sensitivity usually affects specific teeth rather than the entire mouth. Patients often point to a single premolar or molar where the gum has receded. Generalised sensitivity across all teeth indicates widespread enamel erosion.

How Does a Dentist Diagnose Tooth Sensitivity?

A dentist diagnoses tooth sensitivity by reviewing patient history, performing a visual examination, and conducting specific clinical tests. Our team provides accurate diagnoses to design effective treatment plans. You can meet our dentists before your visit.

The diagnostic process includes 6 steps.

1. Patient History: The dentist asks when the sensitivity started. They ask about specific triggers, the duration of the pain, and whether the pain lingers.
2. Visual Examination: The dentist uses a dental mirror and probe to check for enamel wear. They look for receding gums, exposed roots, and signs of tooth decay.
3. Cold Air Test: The dentist uses a dental air syringe to blast cold air onto individual teeth. This test isolates the specific tooth causing the discomfort.
4. Percussion Testing: The dentist gently taps on the teeth. This process rules out a cracked tooth or an infection at the root tip.
5. Digital X-Rays: X-rays reveal hidden issues between teeth. The images show decay beneath old fillings, dental abscesses, and bone loss resulting from gum disease.
6. Bite Test: The dentist asks the patient to bite down on a plastic instrument. Pain upon release indicates a cracked tooth that requires a crown.

Our clinical team brings decades of experience to this diagnostic process. Dr Paul Taylor graduated from the University of Queensland in 1986 and brings 39 years of clinical experience. Dr Ximena Krollner holds a BDS degree and previously served as a Griffith University tutor. The team at Miami Village Dental brings over 30 years of combined clinical experience, and this page was medically reviewed in July 2026. Dr Jijesh Nhalila-Valappil holds a Master’s in Public Health, maintains AACD membership, and is an ADA member. Miami Village Dental holds QIP Accreditation, reflecting strict adherence to Australian safety and infection control standards.

What Treatment Options Are Available for Sensitive Teeth?

Tooth sensitivity treatment targets the exposed dentine or the underlying cause. Dentists select from 7 specific treatments based on the severity of the sensitivity.

1. Desensitising Toothpaste: These over-the-counter products contain potassium nitrate or stannous fluoride. Potassium nitrate blocks nerve signals from travelling to the brain. Stannous fluoride creates a protective barrier over the dentine.
2. Fluoride Varnish: A dentist applies a highly concentrated fluoride gel to the sensitive areas. The varnish hardens the enamel and plugs the open dentine tubules.
3. Composite Bonding: The dentist applies a tooth-coloured resin to cover exposed root surfaces. This material seals the dentine and blocks temperature stimuli.
4. Dental Crowns or Fillings: Structural damage requires restorative dentistry. A dental crown holds a cracked tooth together. A filling repairs a cavity that has reached the dentine.
5. Gum Graft Surgery: Severe gum recession leaves large root surfaces exposed. A periodontist takes tissue from the palate and grafts it over the receded area. This surgery covers the roots and stops the sensitivity.
6. Root Canal Treatment: When sensitivity becomes irreversible, the nerve suffers severe inflammation. Dentists perform root canal treatment to remove the nerve entirely. This procedure eliminates all sensation in the affected tooth.
7. Night Splints: Patients with bruxism require a nightguard. A custom-fitted acrylic splint prevents the upper and lower teeth from touching. This barrier stops mechanical enamel wear.

When Is Tooth Sensitivity a Dental Emergency?

Tooth sensitivity becomes a dental emergency when the pain turns into a constant, throbbing ache or accompanies facial swelling. Routine sensitivity lasts only seconds. Emergency conditions worsen over time and disrupt sleep or daily activities.

Patients must call (07) 5576 7411 immediately if they experience these 4 emergency signs:

1. Constant Throbbing Pain: Pain that lingers for hours after removing a hot or cold trigger indicates nerve damage or a dental abscess.
2. Facial Swelling: Swelling in the jaw, cheek, or gums alongside tooth pain signals a spreading infection. This infection requires immediate antibiotics and drainage.
3. Sensitivity Following Trauma: A fall, sporting injury, or car accident that causes sudden pain indicates structural tooth damage or a dislodged tooth.
4. Spontaneous Extreme Pain: A single tooth causing sudden, severe pain without any trigger requires urgent assessment.

These symptoms indicate serious issues requiring immediate emergency dentistry. An untreated abscess can spread to the jawbone or bloodstream. Contact our clinic for same-day emergency appointments.

How Can You Prevent Tooth Sensitivity?

Preventing tooth sensitivity involves protecting the enamel and maintaining healthy gum tissue. Patients implement 7 preventative strategies at home.

1. Use a Soft-Bristled Toothbrush: Hard bristles scratch the enamel and destroy the gum tissue. Dentists recommend soft or extra-soft bristles.
2. Brush Gently: Aggressive scrubbing causes mechanical wear. Hold the brush at a 45-degree angle to the gums. Use small circular motions rather than sawing back and forth.
3. Limit Acidic Foods: Reduce your intake of lemons, oranges, soft drinks, and sports drinks. These acids demineralise the enamel surface.
4. Rinse with Water: Swish plain water around your mouth immediately after consuming acidic food or drinks. Water dilutes the acid and normalises the oral pH level.
5. Wait Before Brushing: Acidic foods temporarily soften the enamel. Waiting 30 minutes allows saliva to remineralise and harden the enamel surface. Brushing immediately scratches the softened layer.
6. Use Desensitising Toothpaste: Use a sensitive toothpaste formula daily if you have a history of sensitivity. These toothpastes provide ongoing protection for the dentine tubules.
7. Attend Regular Check-Ups: Professional scale and clean removes plaque and tartar. Regular 6-monthly visits allow dentists to detect early decay before it reaches the dentine.

Frequently Asked Questions About Tooth Sensitivity

Can tooth sensitivity go away on its own?
Mild tooth sensitivity goes away on its own when caused by temporary enamel dehydration or recent dental procedures. Sensitivity lasting longer than two weeks or resulting from structural issues like decay requires professional treatment.

Is tooth sensitivity a sign of a cavity?
Tooth sensitivity is a common sign of a cavity when the pain localises to a single tooth and reacts to sweet foods. A dentist uses an X-ray to confirm if decay has breached the enamel and reached the dentine.

How long does sensitivity last after a filling?
Sensitivity after a filling typically lasts 2 to 4 weeks. The drilling process irritates the nerve. The nerve heals and calms down over this period. Contact your dentist if the pain worsens after two weeks.

Can teeth whitening cause sensitivity?
Teeth whitening causes temporary sensitivity because the bleaching gel penetrates the enamel and reaches the dentine layer. This chemical sensitivity resolves within 48 hours after stopping the treatment.

What is the best toothpaste for sensitive teeth?
The best toothpaste for sensitive teeth contains potassium nitrate or stannous fluoride. Potassium nitrate numbs the nerve endings inside the tooth. Stannous fluoride creates a physical block over the microscopic tubules.

When should I see a dentist about tooth sensitivity?
You should see a dentist about tooth sensitivity if the pain lasts longer than a week, prevents normal eating, or triggers spontaneously without temperature changes. Book an appointment to rule out cracks, decay, or nerve damage.
