10 biggest causes of tooth sensitivity

Some of the biggest causes of tooth sensitivity include:

  1. Brushing too hard or too vigorously. You may think that the harder you brush, the more plaque you will tackle. Doing so may actually be doing more harm than good to your tooth enamel as well as your gums. As hard as your teeth are (they are, in fact, the hardest part of your body) they are still sensitive, especially considering their overall health. Teeth can become weak due to poor health or poor nutrition, but brushing too vigorously can also do some damage. Doing so can actually wear down your tooth enamel and may eventually expose the microscopic hollow canals and tubes that house your dental nerves. When sticky or acidic foods and beverages come into contact with these nerves, you will experience discomfort. To counter this, it is best to maybe switch to a soft bristled tooth brush and to be more mindful and gentle with your brushing technique while still remaining thorough.
  1.  Eating acidic foods. As mentioned in the previous bullet-point, acidic foods can have an adverse effect on your teeth. Not only can they cause that sensation related to tooth sensitivity, but eating too much of it can begin to eat away at your tooth enamel that makes the sensation all the more comfortable as well. This is why fluoride treatments and general good oral hygiene is important since it can help strengthen your tooth enamel.
  2. You use too much mouthwash. Some mouthwashes may contain ingredients like alcohol or other chemicals that are known to make your teeth more sensitive. Paying attention to the ingredients in the mouthwash you choose as well as abstaining from rinsing more than once per day or the suggested amount will help your tooth sensitivity.
  3. You use a whitening toothpaste. Some individuals simply happen to be more sensitive to some of the ingredients used to whiten teeth, so using a toothpaste heavy on tooth whitening may cause increased sensitivity.
  4. You have just had a dental procedure completed. Most dental procedures will leave your mouth feeling generally sensitive. The level of this sensation may vary depending on the dental work that you had completed, but this is a very normal side effect that should only be temporary. If your sensitivity lasts more than a few days, then you should revisit your dentist for a follow up to make sure that you do not have an infection or other issue.
  5. You have gum disease. Gum disease can be dangerous, and as the name would suggest, it affects the gums. Gum disease affects your teeth and overall dental health as well, but one of the first signs of gingivitis (early stage gum disease) is tender, irritated and sometimes bleeding gums.
  6. You have significant plaque buildup. Plaque is why you brush and floss on a regular basis. Plaque builds up on tooth enamel and along the gumline throughout the day, and if it is not brushed or cleaned away properly, it will begin to react with the foods that you eat and begin to eat away at your tooth enamel.
  7. There is decay spreading at the edges around old fillings. Dental fillings are used to close up cavities and limit surface area once the tooth has been cleaned and cleared of plaque and decay. But older dental fillings can begin to weaken or crack. This can cause the area to open up, even if it is just little fissures and cracks, where plaque can get trapped, causing more tooth decay. Older fillings can be replaced and should be fixed if this begins to occur.
  8. You have a cracked or chipped tooth. It is not at all uncommon to chip or crack a tooth and not be entirely aware of it, especially if it was sustained as part of another injury or if the injury itself was relatively small. Whether you were somehow injured in the face or simply bit into something too hard, your tooth may experience increased sensitivity afterward. This can alert you to a crack or chip that you otherwise may not have been aware of.
  9. You grind your teeth. Teeth grinding is a serious dental health concern. Most people do it without thinking, whether when they do it when they are stressed or even when they are sleeping, but teeth grinding wears down tooth enamel and over time may eventually expose the inner layers of the tooth, including the nerves.
