For young people, there may not be a certain concept or idea about longevity. However, for middle-aged and elderly people, the topic of longevity often attracts them. However, it should be noted that a person's lifespan is influenced by many factors such as genetics, diet, and environment, and cannot be controlled by us.

However, we can promote physical health through good lifestyle habits and a healthy diet, which is beneficial for extending lifespan. Life expectancy can be seen through daily small things, as well as through mental state. Can life expectancy be known through teeth?

How long is the lifespan, tooth prophet?

Poor teeth can indeed affect a person's health, but teeth are not directly related to lifespan, but there is an indirect connection. Tooth loss is directly related to the pressure a person experiences throughout their lifetime, and stress and poor health are first manifested in the oral cavity.

For an average healthy adult, the number of teeth is generally between 28 and 32. A study has shown that if you lose some or less than 10 teeth, your likelihood of developing a disability within 5 years is equivalent to having 20 elderly people.

And normal teeth are closely arranged with each other, and when adjacent teeth move, there will be gaps between them. Food can easily seep into the gaps, causing bad breath, dental caries, periodontal disease, and so on.

If teeth fall off and are not repaired for a long time, adjacent teeth may tilt due to loss of dependency and restraint, which can easily lead to poor occlusion. Due to the corresponding reduction in effective functional areas between other teeth, chewing efficiency decreases.

Therefore, teeth may have a certain impact on a person's physical condition, but they cannot be said to affect the length of their lifespan.

How many normal teeth are left for a 60 year old person?

Generally speaking, under normal circumstances, a person has 28 to 32 teeth. The reason why they are not fixed is because some people have wisdom teeth, some people do not, and some people have different numbers of teeth, so there are always differences.

If there are 20 left at the age of 80, it is not up to standard. For those born in the 1960s, at least this standard should be met and more should be kept. Generally speaking, a 60 year old person should have 20 to 25 teeth left.

According to the Fourth National Oral Health Epidemiological Survey, among the elderly population aged 65 to 74, there are 22.5 retained teeth.

But as teeth fall off, problems such as tooth deviation and impaired chewing function may occur. At this point, people can restore tooth function and improve their quality of life through dental implants and orthodontics.

Extension: Counting 4 major toothbrushing misconceptions, 90% of people mistakenly brush their teeth

1. Brushing time

Many people are in a hurry and finish brushing their teeth in the morning, but this process takes less than 30 seconds. This perfunctory brushing method does not completely remove bacteria from the teeth, and may also lead to inflammation of various tartar such as tartar and tartar.

It is recommended that everyone brush their teeth for no less than two minutes, which can fully remove the dental calculus and tartar between teeth and avoid the occurrence of dental caries.

2. Brushing teeth vigorously

There are some misconceptions in the process of brushing teeth, and one is that it is not advisable to brush teeth too hard. Many people believe that the stronger the brushing force, the better, which can remove the dirt on the surface of teeth as much as possible.

However, brushing teeth too hard can damage gum tissue, and excessive cleaning of teeth can damage the health of teeth. Therefore, in the process of brushing teeth, it is necessary to master the correct methods, avoid some misunderstandings, and not always use force to brush teeth.

3. Brush your teeth immediately after meals

Some people brush their teeth immediately after eating to prevent food residue from staying in their mouths for a long time. But this can damage the health of teeth, especially after eating a lot of acidic food, it will adhere to the teeth and soften the enamel on the surface of the teeth.

At the same time, acidic substances are prone to react with calcium and phosphorus on teeth, making them fragile. If you brush your teeth immediately, it can also cause damage to the enamel. After meals, you can rinse your mouth with salt water or water to promote the recovery of dental calcium.

4. Regarding water temperature

Relatively speaking, brushing teeth with warm water close to our normal body temperature will have a better effect. Long term brushing with cold water is not conducive to dental health and can easily make teeth sensitive.

In addition, many people are accustomed to wetting toothpaste with water before brushing their teeth, which can easily prevent certain components in the toothpaste from functioning properly and reduce its cleaning ability. So when brushing teeth, it is important to avoid this situation and apply toothpaste directly to dry brush.
