Tooth sensitivity is an extremely unpleasant condition that manifests itself through severe pain. This pain usually occurs as a natural response of the affected tooth of an irritant (sweet, hot, or cold foods and drinks). 

Increased sensitivity usually occurs when the tooth enamel becomes damaged and the irritant can affect the nerve endings on the tooth. In this article, we have gathered five common causes of tooth sensitivity you need to know.

1. Tooth decay

Tooth decay (cavities) is an extremely common oral issue that can cause increased tooth sensitivity and many unpleasant consequences. Even though tooth decay can occur without any symptoms, it can lead to toothache and tooth sensitivity when the damage becomes significant.

The main problem is that it can be difficult to notice the cavity with the naked eye. That’s why many people think that their tooth sensitivity has occurred without any reason. If you experience tooth sensitivity, schedule an appointment with your dentist to fill the cavity. 

2. Teeth grinding

Teeth grinding, also called bruxism, is a condition in which a person clenches their teeth. Many people think that this condition is not dangerous but the reality is that teeth grinding can cause a lot of severe complications. The most common of them are:

• Tooth sensitivity
• Jaw pain
• Loose teeth
• Damage to dental restorations
• Headache

When you constantly clench your teeth, this contributes to enamel wear which results in increased tooth sensitivity. It is important to wear a special night guard to protect your teeth and jaw throughout the night.  

3. Gum recession

Gum recession is a condition that occurs when your gums become loose and expose the root of the tooth. In most cases, it develops along with the progression of gum disease that makes gums weak and vulnerable. People with gum recession can experience severe tooth pain in response to hot or cold foods and drinks. 

If you suffer from gum recession, it is essential to clean your teeth thoroughly to prevent the bacteria overgrowth and aggravation of your condition. Antibiotics can be also used to reduce inflammation. If gum recession is severe, you may need to get surgical treatment. 

4. Dental abscess

A dental abscess is a pocket of pus that occurs under the tooth because of its infection. Untreated tooth decay tends to be the most common cause of the dental abscess. It is important to understand that it is a life-threatening condition that can cause a lot of severe symptoms. The most common of them are: 

• Unbeatable toothache
• Tooth sensitivity
• Unpleasant taste in the mouth
• Bad breath
• Fewer
• Swollen and tender gums
• Swollen lymph nodes

It is essential to treat a dental abscess right after the diagnosis. Otherwise, the pocket can burst and pus may spread to your neck, jaw, and brain. The dentist will remove the pus from the pockets and fill the cavity.

5. Tooth fracture

Tooth fracture occurs when a person breaks a tooth. It can be a crack that occurs on the cap of the tooth or you can lose a part of the tooth. The most common symptoms of tooth fracture include increased tooth sensitivity, pain while chewing food, and gum swelling. If you have noticed at least some of these symptoms, you need to schedule an appointment with the dentist. 

Tooth fracture is an extremely painful condition that should be treated as soon as possible. If you have a crack in the tooth, the dentist can bond it and restore the tooth function. But if you have a chipped piece of the tooth, you may need to get a dental crown.

The bottom line

You should understand that increased tooth sensitivity can’t occur on its own especially if it is constant or reoccurs regularly. Visit your dentist to define the cause of your condition and undergo thorough treatment.
