When the teeth are stimulated by cold, heat, acid, sweet and mechanical action, the symptoms of soreness will suddenly occur. At this time, the symptom shows that you have "tooth sensitivity". So, what to do about tooth sensitivity?

 Why Are Teeth Sensitive?

Most people want to know why teeth are sensitive. In this regard, dental experts say that there are two reasons for tooth sensitivity: one is that the enamel is lost due to various reasons and the essence is exposed. After the dentin is exposed, when various cold, hot, sour, sweet and mechanical stimuli from the outside world, the fluid flow in the dentinal tubules will accelerate, which will stimulate the nerve endings, resulting in soreness and other sensations; the second is gingival atrophy. The resulting exposure of the tooth root, because the tooth root does not protect the enamel leads to the exposure of the tooth root, which causes the dentin to be directly stimulated and causes allergies.

 What to do about tooth sensitivity?

What to do about tooth sensitivity? When you have tooth sensitivity, you will feel tooth pain and discomfort when you eat cold, hot, sour, or sweet food, or when you brush your teeth or bite hard objects. Here are four tips for tooth sensitivity, which can eliminate or relieve tooth sensitivity.

  •  Use tea to protect teeth

Green tea is rich in catetanic acid, fluorine, and tea elements, which help to coagulate proteins in the hard tissues of teeth to form a protective layer and relieve tooth allergies. Tannic acid has the effect of reducing calcium dissolution. Take 1g of green tea leaves each time, chew for 5 minutes, 3 times a day.

  •  Chew walnuts for desensitization

Raw walnut kernels are rich in linoleic acid glycerides, calcium, phosphorus, etc., which will penetrate into and block the dentinal tubules during chewing, reducing the stimulation of the dental nerves. First rinse your mouth with light salt water, put 20g of walnut kernels in your mouth, chew for about 3-5 minutes, and swallow slowly, once a day in the morning and evening.

  •  Apply vitamin E oil

Vitamin E helps to strengthen the repair ability of teeth and surrounding tissues. Rinse mouth with warm boiled water, apply the oil in pure vitamin E capsules to sensitive teeth, prohibit drinking water within 30 minutes, and try to prolong the time that the medicine remains on teeth. 3 times a day.

  •  Use garlic to rub teeth

Garlic contains fluoride and allicin, which can partially seal open dentinal tubules when rubbed against teeth, blocking external stimulation to the dental nerve. Leave the garlic slices for 5 minutes, then rub the sensitive teeth with the garlic slices for 3 minutes, 3 times a day.

Most people's tooth sensitivity is caused by improper daily diet and incorrect tooth brushing methods. Experts say that the outermost part of the tooth is enamel, which protects the softer dentin inside. When the enamel is damaged, the dentin will be exposed, and when it encounters cold, acidic and irritating food, it will be directly transmitted to the nerves. Therefore, understand the four major coups for tooth sensitivity, and you will no longer be afraid of tooth sensitivity!
