Why does my tooth hurt when I drink hot or cold water?

Many people have very sensitive teeth. When they often come into contact with cold or hot objects, they will feel discomfort or even pain in their teeth. In fact, this is what we often call tooth sensitivity when we go to the doctor. The doctor will recommend patients to use some toothpaste to prevent tooth sensitivity, and will also prescribe some medicines to treat tooth sensitivity. So, why does drinking cold or hot water cause tooth pain? Let me give you a detailed introduction below

There are many reasons for toothache, the most common ones are:

1. Acute pulpitis. It is more common in patients with deeper caries. The bacteria enter the pulp cavity from the caries hole, causing congestion and inflammation of the dental nerve. Toothache is often spontaneous, the pain worsens at night, and is more severe after hot or cold stimulation. The pain may also radiate to the face, temples, and ears. When suffering from suppurative pulpitis, the patient's pain is aggravated by heat stimulation, while the pain is reduced or disappears by cold stimulation.

2. Acute periapical inflammation. Caused by factors such as the development of acute pulpitis or trauma. The diseased tooth presents persistent pain, a floating sensation, and a fear of chewing. The patient can point out the diseased tooth correctly, but tapping the tooth will cause pain. At this time, there is no stimulating pain because the nerve of the diseased tooth has been necrotic.

3. Acute periodontitis

4. Periodontal abscess.

6. Food impaction pain.

7. Dry socket.

Guidance:

1. Reduce or eliminate pathogenic irritants: Reducing or eliminating plaque, changing the oral environment, and creating clean conditions are important links in preventing caries. The most practical and effective way is to brush your teeth and rinse your mouth. We should strengthen publicity and education to cultivate oral hygiene habits and learn the proper way to brush teeth from an early age. Brushing your teeth can remove most of the bacteria in your mouth and reduce plaque formation. Try to brush your mouth once in the morning and evening, and rinse your mouth after meals. It is more important to brush your teeth before spitting because the interval at night is long and bacteria can easily multiply. To brush in the correct direction, that is, "brush the upper teeth from top to bottom, brush the lower teeth from bottom to top", "brush inside and outside", and also pay attention to brushing the biting surface of the back teeth. This way, food residues between teeth and on tooth surfaces can be cleaned out. Rinse your mouth after brushing. Don't brush horizontally, as this can easily damage the gums and fail to remove all debris between the teeth.
