What is tooth sensitivity?

Why are teeth sensitive?

What should I do about sensitive teeth?

Don’t worry, today we will answer them all:

What is tooth sensitivity?

After excluding any other form of tooth defects or diseases, the short and sharp pain caused by the exposed dentin to external stimuli is tooth sensitivity, that is, dentin sensitivity.

The external stimuli mentioned here include cold water and cold wind, but if it is caused by tooth decay, it does not belong to the sensitive range of teeth.

Why are teeth sensitive?

Some people may want to ask: since the ache of tooth decay is not called sensitive teeth, then why are good teeth sensitive?

From the perspective of tooth structure, the surface of our teeth is a layer of hard enamel, the middle of which is the pulp tissue containing nerves, and the dentin connecting them.

The dentin contains many dentine tubules containing fluid.

When external stimulation acts on the exposed dentin tubules, causing the fluid in the dentin tubules to flow abnormally, the stimulation is transmitted to the pulp tissue at the other end of the dentin tubules, resulting in sensitive symptoms.

What can cause tooth sensitivity?

1. Tooth wear caused by various reasons

· Brushing too hard.

· Toothbrush bristles are too hard.

· Brush your teeth immediately after eating and drinking acidic drinks.

· Teeth grinding.

2, the role of acidic substances

· Acidic food and drink.

Acid drugs: such as vitamin C, aspirin.

· Working environment with “acid” : such as battery industry workshop, chlorine preparation disinfection of swimming pool, etc.

· Gastric acid in cases of gastroesophageal reflux, pregnancy reaction, etc.

3.Receding gums

When the gums receded, the roots of the teeth were exposed, and they were vulnerable to external irritation, resulting in sensitive teeth.

4. “Bleach”

Some popular cosmetic products may also cause tooth sensitivity, so before using such products, it is recommended to consult a professional dentist and use carefully under the supervision of a dentist.

What about sensitive teeth?

To solve dentin sensitivity, the first thing to know is how it is caused.

Previously, we talked about the mechanism of tooth sensitivity: the exposed dentin tubule transmits the external stimulation through the fluid in the tube to the pulp tissue at the other end, which will produce sensitive symptoms.

Therefore, the treatment of dental sensitivity first needs to go to the hospital in time to find the cause of dental sensitivity and remove this “external stimulation”.

There are two other important aspects:

The first is to block the exposed dentin tubules by various means.

The second is desensitization treatment, so that the dental nerve is not so sensitive.

Daily intervention can be carried out in the following two aspects:

1. Use home care products that contain desensitizing ingredients

· Anti-sensitivity toothpaste.

· Patients use it twice a day for 4 to 8 weeks, which can greatly relieve dentin sensitivity.

· Anti-sensitivity mouthwash.

· Mouthwashes containing anti-sensitivity ingredients can also relieve dentin sensitivity.

2. Professional intervention

· If symptoms do not improve after 2-4 weeks of home care, professional intervention can be performed.

· A desensitizing agent similar to the active ingredient of home care products.

· Occluded dentin tubules by adhesive.

· Occlusive dentin tubules by bioglass and silicate cement.

· Use laser to block dentin tubules.

Finally, a tooth sensitivity prevention tips for friends who do not have any tooth sensitivity symptoms, wish everyone can have a healthy tooth:

· Adopt proper brushing methods;

· Reduce intake of acidic foods and beverages;

· Timely diagnosis and treatment of periodontal diseases, night bruxism, excessive tooth wear and other related diseases;

· Gargle immediately after eating acidic foods and drinks, and brush your teeth at least 1 hour later;

· Careful use of home tooth bleaching products;

· Regular oral check-ups.
