Causes of Tooth Sensitivity
Gum sensitivity can occur due to a combination of many different factors and typically manifests as gum discomfort, pain, or hypersensitivity to hot and cold foods. The main causes include incorrect tooth-brushing techniques, the use of hard toothbrushes, gum diseases, and plaque accumulation. Brushing your teeth too hard or with the wrong technique can cause the gums to wear down and recede. This in turn causes tooth sensitivity as the tooth roots are exposed. Gum recession exposes the dentin layer in the tooth roots, and external factors reaching the nerves through the microchannels in this layer cause pain.
Another common cause is gum disease. Conditions such as gingivitis (inflammation of the gums) and periodontitis (an advanced stage of gum disease) can lead to gum bleeding and sensitivity. These diseases arise from plaque and tartar accumulation that is not regularly cleaned. Plaque is a sticky, colorless layer that harbors bacteria causing infection and inflammation in the gums. The resulting inflammation can make the gums more sensitive and even damaged. Preventing and treating gum disease is crucial for reducing gum sensitivity. Therefore, regular dental visits and good oral hygiene are key to maintaining gum health.
Impact of Improper Tooth Brushing Techniques on Tooth Sensitivity
Improper brushing is one of the most common causes of tooth sensitivity. This usually occurs as a result of brushing the teeth using excessive force or with a hard-bristled toothbrush. Excessive force can lead to persistent gum recession and erosion of tooth enamel. Receding gums expose the dentin layer underneath the enamel, the protective layer of the tooth. The dentin layer contains microchannels that trigger sensitivity to hot, cold, or sweet foods. This condition causes uncomfortable pain and tooth sensitivity in daily life. Therefore, incorrect brushing techniques can have significant long-term negative effects on dental health.
Learning correct brushing techniques is crucial in preventing tooth sensitivity. Using a soft-bristled toothbrush and brushing the teeth with circular movements helps prevent gum recession and tooth enamel wear. Additionally, the toothbrush should be held at the correct angle to avoid damaging the gums while brushing. These simple changes are an effective method to protect the gums and prevent tooth damage.
