Tooth Sensitivity

What Causes Tooth Sensitivity?

Tooth sensitivity happens when the protective enamel wears away, or the gums recede, exposing the dentin (the softer layer beneath enamel) and microscopic nerve pathways. Common causes include:

• Enamel erosion from acidic foods and drinks (soft drinks, citrus, wine)
• Aggressive brushing that wears down enamel and gums
• Teeth grinding (bruxism), leading to micro-fractures and enamel loss
• Gum recession exposing the root surfaces
• Tooth decay or cavities exposing sensitive dentin
• Cracked or chipped teeth, allowing external stimuli to reach the nerves
• Post-dental treatment sensitivity, such as after a filling, whitening, or deep cleaning

If you are experiencing ongoing discomfort, a dental consultation is essential to identify the cause and provide the best treatment option for relief.

How We Treat Tooth Sensitivity

At Avonhead Dental, we offer a simple and effective treatment process to strengthen and protect your teeth:

Step 1: Consultation & Cleaning

We begin with a comprehensive assessment, examining your teeth for signs of enamel wear, gum recession, or underlying conditions. We will:
✔ Identify triggers and recommend lifestyle changes to minimise sensitivity
✔ Gently clean the tooth surface to remove plaque and debris
✔ Discuss suitable at-home care options, such as desensitising toothpaste

Step 2: Application of a Protective Coating

For more persistent sensitivity, we apply a fluoride or desensitising protective coating to strengthen the enamel and block exposed nerve pathways.

✔ A thin layer of protective material is brushed onto the sensitive areas
✔ It acts as a shield, replacing lost enamel and sealing nerve openings
✔ Helps prevent further sensitivity while reinforcing the tooth structure

Step 3: Blue Light Activation & Hardening

To ensure long-lasting protection, we harden the coating using blue light technology. This step ensures:
✔ Immediate sealing and protection against temperature changes
✔ Long-term durability and resistance to acid wear
✔ A stronger, healthier, and pain-free smile

Depending on the severity of your sensitivity, multiple applications may be recommended for optimal results.

Additional Treatment Options for Severe Sensitivity

If sensitivity persists despite basic treatments, we may recommend:

• Dental Bonding – Applying a tooth-coloured resin to cover and protect exposed dentin.
• Gum Grafting – If gum recession is the cause, a minor procedure can restore lost gum tissue and cover exposed roots.
• Night Guards for Teeth Grinding – Prevents enamel wear for those who grind their teeth.
• Root Canal Therapy – For severe cases where deep nerve exposure is causing ongoing pain, a root canal may be needed to remove the affected nerve.

How to Prevent Tooth Sensitivity

✔ Use a soft-bristled toothbrush and gentle brushing techniques
✔ Avoid acidic foods and drinks that erode enamel
✔ Use fluoride toothpaste to strengthen enamel and prevent decay
✔ Wear a mouthguard if you grind your teeth at night
✔ Schedule regular dental check-ups to catch early signs of enamel wear or gum recession
