Tooth Sensitivity: Causes, Treatment, and Prevention

Are you experiencing sharp pain or discomfort when eating ice cream, drinking hot beverages, or brushing your teeth? You could be dealing with tooth sensitivity, a common condition that affects millions of people worldwide.

In this blog, we’ll explain what causes tooth sensitivity, how it’s treated, and what you can do to prevent it in the future.

What Is Tooth Sensitivity?

Tooth sensitivity (also known as dentin hypersensitivity) occurs when the underlying layer of your teeth, known as the dentin, becomes exposed. This happens when the protective layer of enamel or the gum tissue around your teeth wears down. When dentin is exposed, the nerves inside the tooth become more sensitive to stimuli like hot, cold, sweet, or acidic foods and drinks, causing discomfort or pain.

Common Causes of Tooth Sensitivity

There are several factors that can contribute to tooth sensitivity:

1. Worn Enamel

Enamel is the hard, protective outer layer of your teeth. Over time, it can wear down due to:

• Brushing too hard with a hard-bristled toothbrush

• Acidic foods and drinks (like citrus fruits, soda, and wine)

• Teeth grinding (bruxism), which can wear down enamel

2. Gum Recession

When the gums pull back from the teeth, the sensitive roots are exposed. This can happen due to:

• Gum disease (gingivitis and periodontitis)

• Brushing too aggressively or using a hard-bristled toothbrush

• Aging, as gums naturally recede with time

3. Tooth Decay or Cavities

Cavities can cause tooth sensitivity because they break through the enamel and expose the softer parts of the tooth. If you’re feeling pain when biting or chewing, you may have a cavity that needs treatment.

4. Recent Dental Procedures

If you've recently had dental work, such as a filling or teeth cleaning, you may experience some temporary sensitivity. This is common but should subside after a few days.

5. Cracked Teeth or Fillings

A cracked tooth or filling exposes the dentin and nerves, leading to pain when the tooth is stimulated.

6. Acidic Foods and Drinks

Frequent consumption of acidic foods and beverages like citrus fruits, coffee, wine, or soda can erode tooth enamel, leading to sensitivity.

How to Treat Tooth Sensitivity

1. Use Desensitizing Toothpaste

Specialized desensitizing toothpaste contains compounds that help block the transmission of pain signals from the surface of the tooth to the nerve. Regular use can help alleviate sensitivity over time.

2. Switch to a Softer Toothbrush

Use a soft-bristled toothbrush to prevent further damage to your gums and enamel. Brush gently to avoid wearing down the enamel and receding your gums.

3. Fluoride Treatments

Fluoride can help strengthen enamel and reduce pain. Your dentist may apply a fluoride gel or varnish to the affected areas of your teeth to improve protection and reduce sensitivity.

4. Dental Sealants

If you have sensitive teeth due to enamel erosion, your dentist may apply a dental sealant to the affected areas to protect the tooth surface from stimuli.

5. Dental Bonding or Crowns

If the sensitivity is caused by a crack or large cavity, your dentist might suggest dental bonding or placing a crown to cover the affected tooth and protect it from pain.

6. Root Canal Treatment

In severe cases, a root canal may be necessary if the sensitivity is caused by infection or inflammation of the pulp (nerve) inside the tooth.

How to Prevent Tooth Sensitivity

1. Brush Properly

Use a soft-bristled toothbrush and brush gently in small circles. Avoid aggressive scrubbing, which can wear down enamel and irritate your gums.

2. Limit Acidic Foods and Drinks

While it’s okay to indulge in acidic foods and beverages occasionally, try to limit their consumption. Rinse your mouth with water after consuming them to reduce their effects on your teeth.

3. Use a Mouthguard

If you grind your teeth at night, a custom night guard can protect your teeth from further damage and sensitivity.

4. Maintain Good Oral Hygiene

Brush twice a day, floss daily, and visit your dentist regularly for check-ups and cleanings. Keeping your teeth and gums healthy helps prevent conditions that contribute to sensitivity, like gum disease or cavities.

5. Stay Hydrated

Dry mouth can contribute to tooth sensitivity. Drink plenty of water to keep your mouth hydrated and promote saliva production, which helps protect enamel.

When to See a Dentist for Tooth Sensitivity

While tooth sensitivity is common, it can also be a sign of underlying dental problems. If you experience:

• Severe or constant pain

• Pain when chewing or touching a specific tooth

• Bleeding or swollen gums

• Tooth decay or cavities

It’s important to schedule an appointment with your dentist to get an accurate diagnosis and appropriate treatment.

Final Thoughts

Tooth sensitivity can be annoying and uncomfortable, but it’s treatable. By identifying the causes and implementing proper care, you can manage and even eliminate the discomfort. With the right treatment plan and habits, you can protect your teeth from further damage and enjoy a pain-free smile again.

Root Canal Treatment: What to Expect, Cost, and Recovery

Root Canal Treatment: What to Expect, Cost, and Recovery

If you've been told you need a root canal, you might be feeling nervous — but don’t worry. Modern root canal treatment is safe, effective, and relatively pain-free. It’s one of the best ways to save a badly damaged or infected tooth and avoid extraction.

In this guide, we’ll explain what a root canal is, signs you might need one, what the procedure involves, recovery tips, and costs in Australia.

What Is a Root Canal Treatment?

A root canal is a dental procedure that removes infected or inflamed pulp (the soft tissue inside your tooth) and replaces it with a filling to seal and protect the tooth.
It allows you to keep your natural tooth, avoid infection spreading, and eliminate pain caused by deep decay or trauma.

Signs You Might Need a Root Canal

You may need root canal therapy if you experience:

• Persistent toothache or throbbing pain

• Sensitivity to hot or cold that lingers

• Swollen gums near the affected tooth

• Discolouration or darkening of the tooth

• A pimple or abscess on the gum

• Pain when chewing or touching the tooth

Your dentist will confirm the diagnosis using X-rays and clinical tests.

Step-by-Step: How a Root Canal Is Done

1. Numbing the Area

Your dentist will administer local anaesthetic to ensure you're completely comfortable.

2. Removing the Infected Pulp

A small hole is made in the tooth to remove the infected pulp and clean out the root canals.

3. Disinfection and Shaping

The canals are cleaned, shaped, and disinfected to eliminate bacteria.

4. Filling the Root Canals

The empty canals are filled with a special material called gutta-percha, then sealed.

5. Final Restoration

A crown or filling is placed to restore the tooth’s strength and function.

Does a Root Canal Hurt?

Contrary to popular belief, a root canal doesn’t cause pain — it actually relieves it.
With modern technology and local anaesthetic, the procedure feels similar to getting a deep filling. You may feel mild soreness afterwards, which can be managed with over-the-counter pain relief.

Root Canal Recovery Tips

• Avoid chewing on the treated tooth until your final crown is placed

• Brush and floss gently around the area

• Take any prescribed medication as directed

• Mild discomfort is normal for a few days, but contact your dentist if pain worsens

How Long Does a Root Canal Last?

With proper care, a tooth treated with a root canal can last 10–15 years or longer, especially if it's restored with a crown.

How Much Does a Root Canal Cost in Australia?

The cost of a root canal depends on how many canals are treated and whether a crown is needed.
In Australia, the average price is from $1,500 to $5,000. Dental health insurance may cover part of the cost, depending on your policy.

Root Canal vs Extraction: Which Is Better?

Whenever possible, it’s better to save your natural tooth. A root canal allows you to keep your original tooth structure, maintain your bite, and avoid shifting of nearby teeth.
Tooth extraction may seem cheaper short term, but replacing a lost tooth with an implant or bridge can cost much more long term.

Final Thoughts

Root canal treatment is a proven, safe, and highly effective way to save an infected or damaged tooth.
It stops pain, prevents infection, and helps you keep your natural smile for years to come.

Dental Implant Bridge: The Perfect Solution for Multiple Missing Teeth

If you’re missing several teeth in a row, a dental implant bridge could be the ideal solution to restore your smile, function, and confidence — without needing an implant for every single missing tooth.

In this guide, we’ll walk you through what a dental implant bridge is, the procedure, healing time, costs, and why it's often the best long-term option for multiple missing teeth.

What Is a Dental Implant Bridge?

A dental implant bridge is a type of restoration that replaces several missing teeth at once by anchoring an artificial bridge onto two or more dental implants.
Instead of placing an implant for each missing tooth, implants are strategically positioned to support a series of prosthetic teeth, making the process less invasive and more cost-effective.

Who Needs a Dental Implant Bridge?

You may be a good candidate if you:

• Have 3 or more missing teeth in a row

• Have sufficient bone density in the jaw

• Want a permanent solution without removable dentures

• Want to preserve surrounding natural teeth without crowns

If you’re not sure, a consultation with an experienced implant dentist will determine if a dental implant bridge is right for your specific case.

How Does a Dental Implant Bridge Work?

1. Consultation and Planning

Your dentist will perform digital scans, X-rays, and create a detailed plan for implant placement.

2. Implant Placement

Two or more implants are surgically inserted into the jawbone at key points to act as anchors for the bridge.

3. Healing and Osseointegration (3–6 Months)

Your implants will naturally fuse with the bone, creating a strong, stable foundation.

4. Temporary Restoration (Optional)

Some patients receive a temporary bridge during the healing phase for function and aesthetics.

5. Final Bridge Placement

After healing, a custom-made bridge of artificial teeth is securely attached to the implants.

Benefits of a Dental Implant Bridge

• Stronger and more stable than removable dentures

• Preserves jawbone health by stimulating bone growth

• No need to grind down healthy teeth (unlike traditional dental bridges)

• Natural look and feel

• Easier to clean and maintain compared to full dentures

Healing Time for a Dental Implant Bridge

Healing usually takes 3 to 6 months, depending on factors like bone health and your overall healing ability.
During this time, the implants bond with the jawbone, ensuring a long-lasting, secure fit for your new bridge.

How Much Does a Dental Implant Bridge Cost?

Costs vary based on the number of implants, the materials used, and the location of the dental clinic.
In Australia, a dental implant bridge can range from $7,000 to $15,000 or more, depending on how many teeth are being replaced and the complexity of the case.

While it’s an investment, it's important to consider that a dental implant bridge offers decades of function, aesthetics, and comfort compared to cheaper, temporary alternatives.

Final Thoughts

If you're missing multiple teeth and want a permanent, natural-looking solution, a dental implant bridge offers outstanding stability, appearance, and function.
It’s an investment in your health, confidence, and quality of life.
