Tooth sensitivity is tooth discomfort in one or more teeth that is triggered by hot, cold, sweet, or sour foods and drinks, or even by breathing cold air. The most common form of interpreting tooth sensitivity is pain. The pain can be sharp, sudden, and shoot deep into the nerve endings of your teeth.
There are several reasons that could cause tooth sensitivity and the best person to diagnose the correct root cause is a specialized dentist.
We have listed some common reasons below:
- Wear down or Abrasion (removed enamel layer) of tooth: Over time, brushing too hard or using a hard-bristled toothbrush with incorrect brushing technique can wear down enamel and cause the dentin to be exposed. It can also cause recession of the gums (the gum tissue pulls away from the teeth). At Dent Ally, we teach each one of our patients the right tooth brushing technique so this can be prevented.
- Recession of the gums: As gums move away from a tooth because of conditions such as periodontal disease, the root surface becomes exposed that causes sensitivity.
- Gum disease: Inflamed and sore gum tissue may cause sensitivity because of the loss of supporting ligaments, which exposes the root surface that leads directly to the nerve of the tooth.
- Cracked teeth: Chipped or broken teeth may fill with bacteria from plaque and enter the pulp, causing inflammation and sensitivity.
- Teeth grinding/clenching (Bruxism): Grinding or clenching your teeth may wear down the enamel and expose underlying dentin. Also the excessive forces of grinding can lead to pulpal inflammation resulting in sensitivity and pain.
- Tooth whitening products or toothpaste with baking soda and peroxide (using incorrect material & techniques): These products are major contributors to tooth sensitivity. Without getting a recommendation from a dentist, do not use such over the counter products as teeth whitening is a specialized process and should be done only by a specialist dentist.
- Plaque buildup: The presence of plaque on the root surfaces can cause sensitivity due to bacterial build up over the tooth.
- Cavities (Caries): Cavities result in degradation of tooth layers thus causing sensitivity in tooth.
