TL;DR
- Tooth sensitivity occurs when dentin is exposed, allowing hot, cold or sweet stimuli to reach the nerve.
- Occasional twinges are normal, but frequent or sharp pain may indicate enamel, gum or dental issues.
- Common causes include enamel wear, gum recession, cavities, cracked teeth, worn fillings, grinding and aggressive brushing.
- Treatments range from desensitizing toothpaste and fluoride treatments to dental bonding, gum grafts or root canals.
- Preventive steps include gentle brushing, using sensitive-tooth toothpaste, limiting acidic foods, rinsing after meals, regular dental checkups, wearing a nightguard and maintaining a healthy diet.
What is Tooth Sensitivity and Is It Normal?
It is well known that our teeth are made of layers. The outer layer, enamel, is hard and protects the softer parts inside. Beneath it lies dentin, which contains tiny channels that reach the nerve at the center of the tooth. When enamel wears down or gums recede, these channels can become exposed. That exposure allows cold air, hot drinks or something sweet to reach the nerve directly, producing a sudden, sharp twinge. This reaction is what we refer to as tooth sensitivity.
A mild, occasional twinge is common and usually not a cause for concern. It can happen after a dental cleaning, brushing too firmly or eating something very cold or acidic. Frequent or severe pain, however, may indicate enamel erosion, gum recession, cavities or other dental problems. In this article, we will first explore the most common causes of tooth sensitivity and then look at the treatment options recommended in general dentistry.
Common Causes of Tooth Sensitivity
Several factors can make your teeth more prone to sudden twinges or discomfort. Some of the most common causes include:
- Enamel Wear: Over time, enamel can thin due to acidic foods, frequent snacking or natural aging. As enamel wears down, the underlying dentin becomes more exposed, increasing sensitivity.
- Gum Recession: When gums pull back, the roots of your teeth, which lack enamel, become exposed. These areas are highly sensitive to temperature changes and sugary or acidic foods.
- Tooth Decay and Cavities: Even minor decay can allow hot, cold or sweet stimuli to reach the nerve, causing noticeable discomfort.
- Cracked or Chipped Teeth: Any cracks or chips in a tooth can expose the dentin or irritate the nerve, triggering sudden twinges.
- Worn Fillings or Dental Work: Older restorations can wear down, loosen or shift, leaving parts of the tooth sensitive to cold, heat or pressure.
- Teeth Grinding (Bruxism): Repeated grinding or clenching can wear down enamel and expose dentin, leading to sensitivity over time.
- Aggressive Brushing: Brushing too hard or using abrasive toothpaste can wear down enamel and irritate gums, exposing dentin and increasing sensitivity.
What are the Effective Treatment Options for Tooth Sensitivity?
For 15 years, we at RiverRock Dental have helped patients enjoy their favorite foods without wincing from tooth sensitivity. Here are some approaches we take:
- Desensitizing Toothpaste: Specially formulated toothpaste can help block the pathways in the dentin that lead to the nerve. Regular use often reduces sensitivity over a few weeks.
- Fluoride Treatments: Professional fluoride applications strengthen enamel and protect exposed dentin, making teeth less reactive to hot, cold or sweet stimuli.
- Dental Bonding or Sealants: For teeth with exposed roots or small worn areas, our dentists can apply a protective coating to cover sensitive spots and shield the dentin.
- Gum Grafting: In cases of significant gum recession, a gum graft can cover exposed roots, reduce sensitivity and improve overall gum health.
- Replacing or Repairing Fillings: If you experience tooth sensitivity after filling, it may indicate that a filling has worn down, loosened or shifted. Replacing or repairing the restoration can reduce discomfort.
- Root Canal Treatment: In severe cases, when sensitivity is caused by deep decay or nerve irritation, a root canal removes the source of pain while preserving the tooth.
How to Prevent Tooth Sensitivity?
With the right daily habits and professional care, it’s possible to protect your teeth and keep discomfort at bay. Our dentists recommend the following measures:
- Brush gently using a soft-bristle toothbrush and avoid applying too much pressure.
- Use toothpaste made for sensitive teeth to help strengthen dentin and protect enamel.
- Limit highly acidic foods and beverages, such as citrus fruits, soda and certain juices, which can erode enamel over time.
- Rinse with water after having acidic or sugary foods to reduce their effect on your teeth.
- Maintain routine dental checkups and cleanings with our team to catch early signs of enamel wear, gum recession or cavities.
- Wear a nightguard if you grind or clench your teeth to control enamel damage.
- Stay hydrated and eat a balanced diet rich in calcium and vitamins to support dental health.
The Bottom Line
Tooth sensitivity is uncomfortable, and it can make everyday activities like drinking coffee or enjoying a cold dessert unpleasant. While occasional twinges can be normal, frequent or sharp pain usually points to an underlying issue.
At RiverRock Dental, Dr. Todd Christianson, Dr. Nathan Hanson and Dr. Austin Ostrander focus on understanding the exact cause of your sensitivity and treating the root cause.

FAQs
1. Can sensitivity get worse over time?
Yes, it can. If the underlying cause isn’t addressed, enamel and gums can continue to wear down, and what started as a small twinge can turn into constant discomfort. Early care can prevent it from becoming more serious.
2. Can sensitive teeth be treated at home?
Some mild cases respond well to special toothpaste for sensitive teeth, gentle brushing with a soft-bristled brush and avoiding highly acidic foods. But home care alone may not solve the problem if there’s decay, gum issues or worn fillings.
3. Does tooth whitening make sensitivity worse?
It can, in some cases. Whitening products can temporarily increase sensitivity, especially if your enamel is already thin. Your dentist can guide you on safe options and ways to protect your teeth.
4. Does gum disease cause tooth sensitivity?
It can. When gums are inflamed or recede due to periodontal issues, the roots of your teeth become exposed. These areas are more sensitive and prone to discomfort.
5. Can children have sensitive teeth?
Yes, children can experience sensitivity too, often due to brushing too hard, dietary habits or early enamel issues. Regular dental checkups are important to catch it early.
