If you’ve ever felt a sudden, sharp pain in your mouth while sipping a hot coffee or enjoying a cold scoop of ice cream, you’re not alone. Tooth sensitivity is a remarkably common issue, affecting at least 40 million people in the United States, according to the Academy of General Dentistry. But what exactly causes sensitive teeth and, more importantly, what can you do about it? Let’s explore the reasons behind the discomfort and discover effective ways to find relief.
Causes of Tooth Sensitivity
According to the American Dental Association (ADA), tooth sensitivity occurs when the underlying layer of your tooth, called dentin, becomes exposed. Dentin contains microscopic tubules that lead to the tooth’s nerve center. When these tubules are exposed, external stimuli like hot, cold, sweet or acidic foods can reach the nerves, causing pain. Several factors can contribute to the development of tooth sensitivity, including:
- Worn tooth enamel from brushing too hard, consuming acidic foods and drinks, or grinding teeth.
- Gum disease, which can cause gums to recede and expose the sensitive root.
- Cracked or chipped teeth, which can expose the inner layers of the tooth.
- Recent dental work, which may cause temporary sensitivity.
- Old, worn fillings.
- Some teeth whitening products.
Common Triggers
Certain foods and beverages are more likely to exacerbate tooth sensitivity due to their temperature, acidity or sugar content. These include:
- Very hot foods like hot soup and coffee.
- Very cold foods like popsicles and ice cream.
- Acidic foods and drinks like citrus fruits (oranges, lemons, grapefruit), tomatoes, pickles, sodas and sports drinks.
- Chewy sweets like gummy bears, which can get stuck inside open cavities and under gums.
- Hard, crunchy foods like ice and hard candy, which can damage tooth enamel.
Treatments
Tooth sensitivity is often treatable right at home by avoiding offending foods or using a toothpaste specifically designed for sensitive teeth. However, if at-home treatments are not enough, your dentist may recommend an in-office treatment based on the underlying cause of the sensitivity. These may include:
- Fluoride varnish or gel.
- Dental bonding.
- A filling, inlay or crown.
- Gum graft.
- Root canal in more severe cases.
