enamel absorption and tooth sensitivitySensitive teeth

Decayed tooth and exposed root canal causes sensitivity Sensitivity may be defined as a short,sharp pain that is usually initiated by eating hot or cold food or exposure to cold air. Tooth sensitivity is caused by the movement of fluid within tiny tubes located in the dentin (the layer of tissue found beneath the hard enamel that contains the inner pulp) which results in nerve irritation. When the hard enamel is worn down or gums have receded, causing the tiny tube surfaces to be exposed, pain can be caused by eating food or drinking hot or cold beverages, touching your teeth, or exposing them to cold air.

Remedies of sensitive tooth

  • Desensitizing toothpaste:- Widespread tooth sensitivity due to enamel abrasion or gum line recession can’t be treated by dental fillings instead try, brushing with desensitizing tooth paste. These special toothpastes contain ingredients that diminish sensitivity by filling channels (known as tubules) in the dentin. Try putting some of the toothpaste on your finger or on a cotton swab and spreading it over the sensitive spots before you go to bed.Spit but don’t rinse. Within a few weeks, your teeth should begin to feel less sensitive.
  • Fluoride sense:- Fluoride senses available without a prescription at your local pharmacy in the dental section of grocery stores can help decrease sensitivity especially for people plagued with decay problems. Use once a day, swish it around in your mouth, then spit it out . Sometimes, people with sensitive teeth need a stronger fluoride sense or get the ones available over the counter.
  • Keep your teeth clean:- Plaque , the white gummy substance that forms on teeth,produce on acid that irritates teeth, especially if your choppers are naturally sensitive .Wage a daily attack against plaque by brushing at least twice, preferably right after eating and especially before bed and flossing at least once
  • Use a soft toothbrush:- people actually cause tooth sensitivity by brushing with too much force and/or brushing with a hard-bristle brush, which can damage the protective tooth enamel. When the gum line recedes , exposed dentin becomes even more vulnerable to toothbrush abrasion. Use a brush with the softest bristles you can find and apply only a small amount of pressure when bushing.
  • Say Enough to snuff:- Chewing tobacco also known as “dip” or “snuff” is a popular habit in some groups, especially among many male teenagers. They smoke cigarettes. These habits causes the gums to reduce, a major cause of gum sensitivity and decay. Habits like sucking on hard candy while certainly healthier than chewing snuff, it can also cause enamel absorption and tooth sensitivity. Tobacco also causes many other ill effects
  • Visit Dentist at regular intervals:- Get professional tooth cleaning and check cavities.

Causes of sensitive teeth

  1. Brushing too hard:- Over time brushing too hard or using a hard-bristle toothbrush can tear down enamel and cause the dentin to be exposed . It can also cause recession of the gums.
  2. Recession of the gum:- As the gums move away from a tooth due to conditions such as periodontal disease, the tooth surface becomes exposed. This can cause sensitivity.
  3. Gum disease or Gingivitis:- Inflammation and sore gum tissue may cause sensitivity due to the loss of supporting ligament, which exposes the root surface that leads directly to the nerve of the tooth.
  4. Cracked Tooth:- Chipped or broken tooth may fill with bacteria from plaque and enter the pulp causing inflammation. It leads to sensitive teeth.
  5. Teeth Grinding:- Grinding and clenching your teeth may wear down the enamel and expose underlying dentin.
  6. Tooth whitening products:- These products may be major contributors to sensitive teeth.
  7. Your age:- Tooth sensitivity is highest between age of 25 and 30.
  8. Plaque build up:- The presence of plaque on the root surface can cause tooth sensitivity.
  9. Mouthwash use:- Long term use of same mouthwashes, some over the counter mouth- washes contains acid that can worsen tooth sensitivity if you have already exposed dentin. The acids found in these mouthwashes further damages the dentin layers of the tooth.
  10. Acidic foods:- Regular consumption of foods with high content of acids, such as citric fruits, tomatoes, pickles and tea can cause enamel erosion, leading to sensitivity.
  11. Recent dental procedures:- sensitivity can occur following teeth cleaning, root planing, crown placement and tooth restoration. Sensitivity caused by dental procedure is temporary and usually disappearing in three to six weeks.
