how to strengthen tooth enamel

Tooth sensitivity is a problem that affects a large part of the population. Detecting the symptoms is not complicated, but what many people do not know is that there are different ways to strengthen tooth enamel to avoid the discomfort caused by tooth sensitivity.

What is tooth sensitivity?

Tooth sensitivity is an acute pain that occurs in the teeth due to exposure to certain thermal, chemical or tactile stimuli. It is a very common pathology in young adults between 20 and 45 years of age, although it can also occur in children and older adults.

This form of sensitivity can have different levels depending on each person. The type of sensitivity in the teeth can also be different, varying in response to external stimuli such as cold, heat, sweet or acidic foods, or through touch by direct contact.

Why does tooth sensitivity occur?

Teeth are made up of several layers of tissue. The outermost, the enamel, is the hardest and protects the teeth. Inside is the dentine, which contains thousands of nerve endings that are responsible for sensitivity.

When dentine is exposed, external stimuli can reach the dentine and travel through small channels, causing a sharp, short-lasting sting, known as tooth sensitivity.

The causes of tooth sensitivity can vary greatly depending on the degree and conditions of each person. Among them, there are two main reasons why it usually appears:

  • Wear and tear of the enamel, either due to the passage of time, the effect of rough brushing or the action of acidic food and drink.
  • Recession of the gums, leaving the base of the tooth exposed where the dentine is not covered by enamel.

How do I know if I have tooth sensitivity?

Not many people can easily detect the symptoms of tooth sensitivity. Especially when they are weaker or just beginning, it can be difficult to recognise tooth sensitivity.

In general, the symptoms of sensitivity described by most sufferers are as follows:

  • Throbbing pain on mild stimulation.
  • Very short duration of pain to the stimulus in question.
  • Immediate localisation of the area where the pain is felt.

If you usually notice a very intense pain in the same area of your mouth whenever you eat a cold, hot or very acidic food in certain circumstances, it is time to take action and strengthen your teeth against tooth sensitivity.

Strengthening and caring for enamel to combat tooth sensitivity

Without a doubt, the best way to prevent and avoid tooth sensitivity is to follow proper oral hygiene. To do this, there are specific oral hygiene instruments and products that help to strengthen the tooth enamel, protecting it every day.

Toothbrushes for tooth sensitivity

To avoid tooth sensitivity, the first step is to use a specific toothbrush with soft or very soft filaments. The KIN Extrasoft toothbrush is the ideal choice for oral hygiene in cases of severe or moderate hypersensitivity. The extra hard soft filaments clean the teeth gently without damaging the enamel.

Desensitising toothpastes and mouthwashes

Laboratorios KIN has a specific line for the daily care of sensitive teeth. The Cariax Desensitising toothpaste and Cariax Desensitising mouthwash, both formulated with potassium nitrate and fluoride, take care of your tooth enamel on a daily basis, helping to alleviate the dental discomfort caused by sensitivity.

To ensure a more complete daily oral hygiene, it is recommended to rinse twice a day, morning and night, with 15 ml of the undiluted product for 1 minute after brushing.
