Causes of tooth pain after exposure to hot or cold

When you take a dental appointment the first thing your doctor will do is to determine the causes or the reasons for that dental sensitivity.

Well, every case is different, and habits or experience that leads to dental sensitivity varies from person to person, but the underlying causes, or if you look into deeper details, the causes are typically the same.

Before you get into the exact details or causes of tooth sensitivity, you must learn the tooth structure in detail.

Every tooth is consist of a three-layer, the outer hard layer is called the enamel a defense system of the tooth. The enamel protects the softer inner layers of the teeth. This layer is hard to break and requires constant unhygienic routines or regimens to get it punctured.

Right below the enamel, there is a layer of microscopic tubes that leads into the innermost layer of the tooth called the pulp. The nerve system of the teeth is housed inside the pulp.

Dental sensitivity occurs when the dentin or the nerve system of the tooth is exposed to hot or cold, which means the outer layer called enamel is completely broken and letting liquid or other food have direct contact with the nerve system.

But the reasons why your teeth are sensitive to cold can be different than sensitive to hot. Let’s unearth.

Your tooth is sensitive to Cold because

1. Gum disease

Your tooth is cold sensitive, one of the reasons can be gum disease or infection. The top reason for gum infection can be plaque buildup. When a large amount of plaque is built up on the gum, it leads to cold sensitivity.

Brushing too hard: You use abrasive toothpaste, and try to clean your teeth as fast as possible in the shortest time, and to get that, you go too hard on your teeth. Brushing too hard with a hard bristled brush can too lead to cold sensitivity.

2. Gum receding

A very thin part of the hard surface aka enamel covers the sensitive nerves housed inside the pulp. When the gum recedes it leads to the roots exposing, and when you drink something cold it triggers the nerves and makes you suffer with a sudden severe burst of pain.

3. Crackles in the teeth

Teeth expand and contract with temperature. If there are cracks in the teeth, and when the tooth expands due to temperature, the crevices or cracks in the tooth can too expand leading to another access point to the nerve, leading to cold sensitivity.

Your tooth is sensitive to hot because

1. Longer teeth whitening treatment

If you are obsessed with teeth whitening treatment that goes for over weeks, that too can lead your teeth sensitive to heat. It’s completely Okay to take whitening treatment twice a Year, but don’t opt for the treatments that take weeks.

2. Acidic Diet

If you consume too much of a diet rich in acids, that too leads to your tooth being sensitive to hotness. Coffee, tomato sauce, wine, and many other such foods.

Symptoms of temperature sensitivity

The top symptom is a pain when your tooth is exposed to hot or cold. But, how long the pain lasts, or the type of pain you experience can make you learn how you can fix it.

But the treatment plan is determined by how long the pain lasts.

  • Less than 15-seconds

If pain lasts for 15 seconds or less than 15 seconds that means things are not that serious. It does not mean that you should overlook it, that means, you should start noticing things and refrain from eating those foods bad for your teeth’ health.

Yes, that means you don’t require instant medical help, but you should take a dental appointment and get a thorough checkup to learn why this happening is.

In most cases, it can be due to mild tooth decay, a loose or lost filling, or minor gum recession.

  • 30-Seconds

If pain lasts for 30-seconds or more, that means there is something serious and you are likely to suffer permanent damage to the internal structure of the tooth.
