Article 7 SENSITIVE TEETH PROBLEM
Tooth sensitivity is discomfort felt in one or more teeth that is triggered by hot, cold, sweet, or sour foods and drinks, or even by breathing cold air. The pain can be sharp, sudden, and shoot deep into the nerve endings of your teeth.
What Causes Sensitive Teeth?
Sensitive teeth occur when the underlying layer of your teeth — the dentin — becomes exposed as a result of;
- damage of overlying enamel tissue,(by physical or chemical factors) or
- receding of gum tissue so the roots, which are not covered by hard enamel.
The dentin contains thousands of tiny tubules leading to the tooth’s nerve center (the pulp). These dentinal tubules (or channels) allow the stimuli — for example, the hot, cold, or sweet food — to reach the nerve in your tooth, which results in the pain you feel.
There are many factors that may lead to sensitive teeth, including.
- Brushing too hard. Over time, brushing too hard and especially in a ’to and fro’ fashion, or using a hard-bristled toothbrush 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).
- Tooth decaydestroys the enamel cover and cause cavity formation.
- Recession of the gums. As gums move away from a tooth due to conditions such as periodontal disease, the root surface becomes exposed.
- Gum disease (gingivitis). Inflamed and sore gum tissue may cause sensitivity due to 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.
- Teeth grinding. Grinding or clenching your teeth may wear down the enamel and expose underlying dentin.
- Tooth whiteningproducts. These products may be major contributors to sensitive teeth.
- Plaque build-up. The presence of plaque on the root surfaces can cause sensitivity.
- Mouthwash use. Some over-the-counter mouthwashes contain acids that can worsen tooth sensitivity if you have exposed dentin. The acids further damage the dentin layer of the tooth. If you have dentin sensitivity, ask your dentist about the use of a neutral fluoride solution.
- Acidic foods. Regular consumption of foods with a high acid content, such as citrus fruits, tomatoes, pickles, and tea, can cause enamel erosion.
- Recent routine dental procedures. Sensitivity can occur following teeth cleaning, root planing, crown placement, and tooth restoration. Sensitivity caused by dental procedures is temporary, usually disappearing in four to six weeks.
What Can I Do to Reduce Tooth Sensitivity?
Some steps you can take to prevent tooth sensitivity include:
- Maintain good oral hygiene. Continue to follow proper brushing techniques to thoroughly clean all parts of your teeth and mouth.
- Use a soft bristled toothbrush. This will result in less toothbrush abrasion to the tooth surface andless irritation to your gums. Brush gently and carefully in an up and down fashion so you do not remove more gum tissue.
- Use desensitizing toothpaste. There are several brands of toothpaste available for sensitive teeth. With regular use you should notice a decrease in sensitivity. You may need to try several different brands to find the product that works best for you. Another tip. Spread a thin layer of the desensitizing toothpaste on the exposed tooth roots with your finger before you go to bed. Do not use a tartar control toothpaste; rather, use a fluoridated toothpaste.
- Watch what you eat. Frequent consumption of highly acid foods can gradually dissolve tooth enamel and lead to dentin exposure. They may also aggravate the sensitivity and start the pain reaction.
- Use fluoridated dental products. Daily use of a fluoridated toothpaste or mouth rinse can decrease sensitivity. Ask your dentist about available products for home use.
- Avoid teeth grinding. If you grind or clench your teeth, use a mouth guardat night.
- SEE YOUR DENTIST at regular intervals. Get professional tooth cleaning, oral hygiene instructions, and fluoride treatments every six months (or sooner depending on your condition).
