Dental discomfort often arises from two common issues: cavities and tooth sensitivity. While both can cause pain, they are distinct conditions with different causes, symptoms and treatments. Understanding what’s the difference between cavities and tooth sensitivity? will help you manage your oral health more effectively. Let’s take a closer look at each condition.
What Are Cavities?
Cavities, also called dental caries, occur when acid-producing bacteria damage the tooth. These bacteria feed on sugars and starches from food, producing acids that erode the tooth’s enamel. If untreated, cavities can reach the dentin and pulp, causing severe pain.
Symptoms of Cavities:
- Visible holes or dark spots on the teeth
- Pain or discomfort while chewing or biting
- Sensitivity to hot or cold foods
- Toothache that worsens over time
Treatment for Cavities: A dentist treats cavities by removing the decayed part of the tooth and filling it with materials such as amalgam, resin, or porcelain. In severe cases, a root canal may be necessary if the decay affects the tooth pulp.
What Is Tooth Sensitivity?
Tooth sensitivity, or dentin hypersensitivity, occurs when the protective enamel wears away, exposing the dentin. The dentin contains nerve endings that become irritated when exposed to certain stimuli, like temperature changes or acidic foods.
Symptoms of Tooth Sensitivity:
- Sharp pain when consuming hot, cold, sweet or acidic foods and drinks
- Pain while brushing or flossing, especially near the gumline
- Temporary discomfort that fades when the stimulus is removed
Causes of Tooth Sensitivity:
- Worn enamel from aging or aggressive brushing
- Gum recession, which exposes the dentin
- Cracked teeth or fillings
- Teeth grinding (bruxism)
- Acidic foods and drinks that erode enamel
Treatment for Tooth Sensitivity: To manage tooth sensitivity, use desensitising toothpaste, fluoride treatments, or dental sealants to protect the exposed dentin. If gum recession is a cause, your dentist may recommend a gum graft.
What’s the Difference Between Cavities and Tooth Sensitivity?
Cause:
Cavities result from bacterial acids causing tooth decay, while tooth sensitivity stems from enamel wear, gum recession, or exposure of the dentin.
Symptoms:
Cavities cause visible damage, like holes and dark spots, along with persistent pain. Tooth sensitivity, on the other hand, results in sharp, fleeting pain triggered by hot, cold or acidic foods.
Treatment:
Cavities require restorative dental work, such as fillings, while tooth sensitivity is typically managed with desensitising products or fluoride treatments unless more severe issues like gum recession are present.
Conclusion
What’s the difference between cavities and tooth sensitivity? It boils down to their causes, symptoms, and treatments. Cavities arise from tooth decay, leading to visible damage, while tooth sensitivity results from exposed dentin and causes temporary discomfort. Both conditions can cause pain, but they require different treatments.
If you experience any of these issues, visit your dentist for an accurate diagnosis and appropriate treatment plan. Regular dental check-ups will help prevent cavities and detect early signs of tooth sensitivity, ensuring your smile stays healthy and pain-free.
