Sensitive teeth

Doctors usually call it hyperesthesia. We call it dental sensitivity. It can be felt when eating sweet, hot or cold foods or even when you get out in the cold winter air. The main reason why you feel pain when you actually shouldn’t is because the protective layer of the tooth, responsible for keeping it safe from the external factors is damaged.

The main reasons for tooth sensibility are:

  • Acid foods

Oranges, tomatoes, fruit juices, they are all tasty and healthy. Though, when using them in excess they can cause problems by affecting our teeth. The dental outer layer, the enamel erodes. In this way the second layer of the tooth, the dentin is exposed. In order to neutralize the acids contained in these kinds of foods you can eat cheese or drink a glass of milk every time you consume acid foods.

  • The mouthwash

Mouthwashes contain, as well, great deals of acid substances. Even if you like having a fresh breath and you care about you oral hygiene, you need to know that using the mouthwash in excess can cause you more damage than good.

  • Tooth whitening

The new tooth whitening procedures are based on the use of hydrogen peroxide, which is one of the main causes of dental hyperesthesia. There are also tooth pastes known for their capacity of tooth whitening that contain the same hydrogen peroxide. The tooth sensitivity, in these cases is usually temporary and it stops whenever the person stops the use of the specific substances.

  • Gum retraction

The gum has one main function. It protects the dental roots. The dental roots, in turn have in their structure thousands of little canals connected to the central nerve of the tooth. This is why, in case you suffer from a periodontal disease your gum retracts from your teeth so that the roots become exposed, as well as the little canals. This situation leads to the indirect exposure of the central nerve of the tooth, responsible for its sensitivity.

  • An aggressive brushing

The idea that a more aggressive brushing of the teeth leads to cleaner teeth is wrong. The more aggressive are the moves of the toothbrush on the enamel of your teeth and the more often you use hard bristled toothbrushes the more affected gets the outer layer of your teeth. It can also cause gum inflammation or even retraction.

  • Recent dental restorations

Even if it doesn’t sound true, the dentist’s operations on your teeth can lead to their temporary sensitivity.

  • Cracked teeth

Different bad habits, such as chewing on pens, biting on fingernails, bruxism (teeth grinding) can lead to the cracking of the outer or inner layers of your teeth. Once this has happened, the dental pulp inflammation can occur and therefore the dental sensitivity. The bacteria stuck in these cracks can also exacerbate the pain.

  • Bruxism

Even though the enamel is considered to be the most resistant tissue in the whole body, it can be deteriorated because of the vicious habit called bruxism (the grinding of the teeth). It can be treated depending on its cause: stress, dental issues, etc.

  • Dental decay

Caries, the main cause of teeth loss, begins with the enamel damage. It evolves and the sooner the damage gets to the soft tissue of the tooth, the sooner you feel pain.
