- Acidic foods and drinks (e.g., citrus, soft drinks, pickles) that erode enamel.
- Brushing too hard or using a hard-bristled toothbrush.
- Gum recession from periodontal disease, ageing, or over-brushing.
- Cracked or chipped teeth, letting bacteria in.
- Teeth grinding (bruxism), which wears away enamel.
- Plaque build-up near the gum line.
- Teeth whitening products that can temporarily increase sensitivity.
- Recent dental treatments, such as fillings or cleanings (usually short-term).
- Developmental enamel defects, such as enamel hypoplasia (thin enamel).
Questions to ask your dentist include:
- What’s causing my sensitivity?
- Do I need treatment?
- How can I stop it from getting worse?
- What products or habits do you recommend?
- Desensitising toothpaste — contains ingredients that either block nerve signals or form a protective barrier over dentin.
- Fluoride varnishes or gels — strengthen enamel and reduce pain.
- Dental bonding or sealants — cover exposed root surfaces.
- Mouthguards — protect against grinding damage.
- Restorative treatment — fillings, crowns, or repairs for decay or cracks.
- Root canal therapy — in severe cases where the nerve is affected.
Good oral hygiene and lifestyle choices can reduce or prevent sensitivity:
- Brush twice daily with fluoride toothpaste and floss once a day.
- Use a soft-bristled toothbrush and gentle technique to avoid gum recession.
- Avoid brushing immediately after acidic meals/drinks — wait at least 60 minutes.
- Limit acidic and sugary foods/drinks that wear enamel.
- Drink plain water, avoiding citrus-infused water sipped over long periods.
- Address grinding or clenching with a professionally fitted mouthguard.
- See your dentist regularly for check-ups and cleaning.
