Sensitive teeth often manifest as a short, sharp flash of pain when consuming hot, cold, sweet, or acidic foods and drinks. This discomfort occurs when the protective enamel wears down or gums recede, exposing the underlying dentine. Dentine contains tiny tubules that lead directly to the tooth's nerve, causing a reaction when triggered by external temperatures or certain textures.
In the Indian context, the frequent consumption of acidic drinks or very hot tea can contribute to the thinning of tooth enamel over time. Additionally, using a hard-bristled toothbrush or applying too much pressure while brushing can cause the gums to pull away from the teeth. This exposure makes the teeth vulnerable to sensitivity and requires a professional assessment to determine the extent of the wear.
A dentist diagnoses sensitivity by reviewing your clinical history and performing a physical examination. They may use a blast of air or a cold probe to identify specific sensitive areas. The goal is to rule out other conditions such as tooth decay, a cracked tooth, or a leaking filling, which can mimic the symptoms of simple dentine hypersensitivity.
Treatment depends on the underlying cause identified during the diagnosis. If the sensitivity is due to enamel loss, a dentist might recommend specific toothpastes or apply fluoride gels to strengthen the area. If gum recession is the cause, they will address the gum health. Persistent sensitivity should always be evaluated by a dental professional to ensure there is no hidden damage.
