Tooth Sensitivity
Tooth sensitivity has a number of causes, but the most common culprit is the exposure of “dentin.” This is the softer part of the tooth that lies under the enamel.
The dentin is made up of tubules leading to the nerve in the center of the root. These tubules are filled with fluid and move around when cold or hot drinks and food are consumed. This causes the nerve endings to react, which often triggers an acute, sharp pain in the tooth.
There are a lot of factors that may cause tooth sensitivity, such as:
- Brushing vigorously: Brushing too hard or using a hard-bristled toothbrush can wear down the enamel of the teeth, causing the dentin to be exposed. This can lead to the recession of the gums, as well as tooth sensitivity.
- Receding gums: As gums move away from the teeth, the root surface becomes exposed, making it more vulnerable and sensitive to temperature.
- Gum disease: Sore and inflamed gum tissue could actually cause tooth sensitivity, because the supporting ligaments are lost, and the root surface of the teeth becomes exposed.
- Teeth grinding: Clenching and teeth grinding can wear down the enamel of the teeth and expose the dentin.
- Age: 25-30 years old are more vulnerable to tooth sensitivity.
- Recent dental procedures: Sensitivity can happen after some dental procedures, such as root planning, cleaning, tooth restoration, and crown placement. This is usually temporary, and disappears after four weeks.
Now that we have discussed some of the most common causes of tooth sensitivity, let’s now move on to the tooth sensitivity treatments.
The Use of Desensitizing Toothpaste
There are certain desensitizing toothpaste that can alleviate the pain brought by tooth sensitivity. These toothpastes are often packed with ingredients that can desensitize the dentinal tubules of the teeth for a certain period. One of the most common ingredients used in desensitizing toothpaste is potassium nitrate.
At Home Treatments
- Stay away from acidic foods and drinks. They can strip off the enamel of the teeth.
- When consuming acidic beverages, it’s advisable to use a straw.
- Soft-bristled toothbrushes are preferable.
- Avoid consumption of very hot or cold beverages.
- Visit your dentist for regular checkups.
There are several treatments available, and your dentist can help you find those remedies that will work best for you. As a rule of thumb, always consult a professionals, like Drs. Joseph P. Sextonand Carner, and don’t try to diagnose the problem yourself.
