What to Do If You Have Sensitive Teeth
Last updated: 3 August 2025
Step 1: Identify the Triggers
Pay attention to what causes the sensitivity. Common triggers include hot or cold food and drink, sweet or acidic items, brushing your teeth, or even cold air. Knowing your triggers helps you and your dentist pinpoint the root cause.
Step 2: Switch to a Toothpaste for Sensitive Teeth
Use a specially formulated toothpaste for sensitive teeth, such as Sensodyne or Colgate Sensitive. These products help block pain signals and protect exposed dentin over time. Be consistent — it may take a few weeks to feel the full effect.
Step 3: Adjust Your Brushing Technique
Brushing too hard or using a hard-bristled toothbrush can wear down enamel and expose nerve endings. Use a soft-bristled brush and brush gently using circular motions. Avoid brushing immediately after acidic food or drink, as your enamel will be weakened temporarily.
Step 4: Avoid Acidic and Sugary Foods
Cut down on acidic foods (like citrus fruit, vinegar, and fizzy drinks) and sugary snacks that can wear down enamel or aggravate cavities. Drinking water after meals can help rinse away acid and reduce damage.
Step 5: Book a Dental Check-Up
If sensitivity persists or worsens, see your dentist. Common causes of tooth sensitivity include:
- Worn enamel or exposed dentin
- Gum recession or gingivitis
- Tooth decay or cavities
- Cracked or chipped teeth
- Teeth grinding (bruxism)
Your dentist can carry out tests to identify the cause and recommend treatment options such as fluoride varnish, bonding agents, sealants, or a mouthguard.
Step 6: Consider Dental Treatments
In more severe cases, your dentist might recommend professional treatments to reduce sensitivity, such as:
- Desensitising varnishes or gels
- Filling worn enamel or exposed roots
- Gum graft surgery (for receding gums)
- Root canal treatment (if the nerve is exposed)
Preventing Future Sensitivity
To prevent sensitive teeth in the future, maintain good oral hygiene, visit your dentist regularly, and use products suited for sensitive teeth. Don’t ignore ongoing discomfort — it could be a sign of a deeper issue.
