Sensitive Teeth Causes and Solutions
Sensitive teeth can make everyday activities such as eating, drinking, or brushing a stressful experience. For some, sensitivity is mild, triggered by cold or sweet foods. For others, it can cause sharp, sudden pain that affects overall quality of life.
At London Dental Centre, we have over 15 years’ experience treating patients with sensitive teeth. Our team provides comprehensive dental care, including general dentistry, cosmetic treatments, veneers, porcelain veneers, Invisalign, composite bonding, implants and periodontal surgery.
Understanding the causes of sensitivity and the treatment options available can help you manage discomfort and maintain healthy, comfortable teeth.
What Causes Sensitive Teeth?
Tooth sensitivity arises when the inner layers of the tooth—dentin and nerve endings—become exposed. Common causes include:
Enamel erosion – Acidic foods, drinks or gastric reflux can wear down enamel, exposing the sensitive dentin.
Gum recession – Receding gums reveal the tooth roots, which lack protective enamel.
Tooth decay – Cavities can lead to sensitivity, especially when decay reaches deeper layers.
Cracked or fractured teeth – Damage to teeth can expose the inner dentin, causing sharp pain when eating or drinking.
Worn fillings or restorations – Old dental work may allow exposure to sensitive areas.
Bruxism (teeth grinding) – Grinding or clenching wears down enamel and causes sensitivity.
Whitening products – Some whitening treatments may temporarily increase sensitivity.
Identifying the underlying cause is crucial. While over-the-counter remedies can provide temporary relief, professional assessment ensures long-term solutions and prevents further damage.
Symptoms of Sensitive Teeth
Common signs of tooth sensitivity include:
Sharp pain when consuming hot, cold, sweet, or acidic foods
Discomfort during brushing or flossing
Occasional dull ache around affected teeth
Pain that comes and goes or intensifies over time
If sensitivity persists for more than a few weeks or worsens, it is important to see a dentist to rule out cavities, gum disease or other oral health issues.
Solutions for Sensitive Teeth
Treatment for sensitive teeth varies depending on the cause. At London Dental Centre, our approach combines immediate relief with long-term preventive care.
1. Professional Assessment and Diagnosis
Our dentists conduct thorough examinations, including dental X-rays if necessary, to identify the root cause of sensitivity. This ensures the right treatment plan is chosen.
2. Desensitising Toothpaste and Topical Treatments
For mild sensitivity, desensitising toothpastes containing potassium nitrate or fluoride help block pain signals and strengthen enamel. Professional fluoride varnishes applied in the clinic provide additional protection.
3. Gum Treatment
For sensitivity caused by gum recession, periodontal therapy can restore gum health and cover exposed tooth roots. In severe cases, gum grafts may be recommended.
4. Restorative Dental Treatments
Cavities, cracked teeth or worn fillings can be repaired with restorative dentistry. Options include:
Composite bonding – Conserves natural tooth structure while covering exposed dentin.
Veneers and porcelain veneers – Ideal for protecting front teeth with enamel loss, improving both function and aesthetics.
Crowns – Used for more extensively damaged teeth to provide full coverage and protection.
5. Lifestyle and Dietary Adjustments
Reducing acidic foods and drinks, using a soft-bristled toothbrush, and avoiding aggressive brushing techniques can significantly reduce sensitivity.
6. Nightguards for Bruxism
Patients who grind their teeth benefit from custom-made nightguards, which protect enamel and prevent sensitivity caused by pressure and wear.
7. Whitening Considerations
Patients interested in cosmetic treatments such as tooth whitening should consult a dentist first. Pre-existing sensitivity can be managed with tailored whitening protocols.
Prevention of Sensitive Teeth
Maintaining oral health is key to preventing sensitivity:
Brush gently with fluoride toothpaste twice daily
Floss daily to remove plaque and prevent gum recession
Avoid excessive acidic or sugary foods
Attend regular dental check-ups for early detection
Consider protective treatments like fluoride varnish or dental sealants
By combining preventive care with timely treatment, sensitive teeth can be managed effectively, improving both comfort and oral health.
Cosmetic Dentistry Options for Sensitive Teeth
For patients seeking aesthetic improvement alongside sensitivity relief, cosmetic solutions can be highly effective:
Veneers and porcelain veneers – Protect enamel while improving appearance, ideal for chipped or worn teeth
Composite bonding – Repairs cracks, erosion, and minor cosmetic issues, while protecting sensitive areas
Invisalign – Corrects misalignment that may contribute to uneven pressure and sensitivity
Integrating cosmetic and functional care ensures teeth remain both healthy and attractive.
