How long does an electric  toothbrushes last?

How long can an electric toothbrush last? In fact, what affects its service life is composed of many details. I will help you analyze them one by one:

  1. A humid environment will greatly affect the service life!

It is recommended that you do not put the electric toothbrush in the bathroom. After all, water vapor will still penetrate into it. Long-term exposure to a humid environment, long-term bubbling of water in the mouthwash cup, frequent charging, etc., will cause the internal parts of the electric toothbrush to be easily damaged. It will definitely affect the service life. In addition, after using the electric toothbrush, we need to keep it dry and place the electric toothbrush in a cool and ventilated place, which can avoid mold and rust on the internal parts of the electric toothbrush, and can also effectively prolong the life of the electric toothbrush.

  1. The waterproof function needs to be excellent!




















In terms of waterproofing, mainstream brands can basically achieve IPX7 waterproofing. However, it is not completely sealed. There are circuit boards, batteries, motors and other components inside. If it is exposed to moisture for a long time or the waterproofness is not good, water vapor will enter the interior of the electric toothbrush, which will easily corrode the circuit board and battery, greatly reducing the life of the electric toothbrush. Therefore, on the one hand, everyone should pay attention to wiping and saving after use, and on the other hand, give priority to the purchase of products with better workmanship in the middle and high-end.


  1. The problem of battery attenuation is widespread

The battery is an important part of the electric toothbrush. At present, the main lithium battery is on the market. After a long time of aging, the resistance of the battery will increase significantly, so the battery can discharge less electricity, and the capacity will become smaller. In addition, the memory effect is still Yes, so the capacity of the battery will be further reduced. Generally, in 2 years, the battery of the electric toothbrush is only 80% of the original capacity. It is recommended that you use it regularly and do not leave it vacant for a long time, which can better extend the life of the battery.

  1. The life of the brush head is generally about 3 months

The brush head of an electric toothbrush is a consumable item, and it needs to be replaced every three months or so, because after a long time, the brush head will be worn out, the bristles will be split and other problems, which not only hides dirt and hides bacteria and other dirty things , can also cause irritation to the gums and damage to the mouth, so be sure to replace them regularly.

Tests have confirmed that if the toothbrush is eaten for more than 3 months, the bristles of the toothbrush will be filled with a large number of bacteria, including non-pathogenic and pathogenic bacteria. Regardless of whether the user’s mouth is damaged or healthy, germs will enter the human body through the wound or esophagus, causing disease.

The 3 months mentioned here is the generality of an experiment, and 3 months is a recommended cycle of use, but the specific time varies from person to person. For example, some people brush their teeth hard, so the bristles will deform quickly, and another example is a cold. The toothbrush you used at the time, if you continue to use it after it is healed, may also have the possibility of catching a cold again.

In these three situations, the toothbrush is recommended to be replaced.

  1. The bristle spacing becomes wider and messier

Under normal circumstances, the bristles are densely arranged. If the distance between the bristles is significantly wider, the dirt is more likely to remain on the root of the toothbrush. It is best to replace it with a new one.

  1. Most of the bristle tips are soft and collapsed

We brush our teeth twice a day, so the bristles are prone to collapse, especially for soft toothbrushes.

  1. The color of the roots of the bristles becomes darker













The dirt at the root of the bristles of the toothbrush will slowly accumulate, which is the most important reason for the growth of bacteria. When the color of the roots of the bristles is darker, it is a signal that there are more bacteria accumulated in the dirt, and it must be replaced in time, otherwise the bacteria will enter the body with the oral cavity and cause more serious consequences.

Advice on the use of toothbrushes:

  1. After brushing your teeth, rinse the toothbrush repeatedly to dry the moisture on the bristles as much as possible. Place the brush head up and handle down in a cup or ventilated place and let it dry. Do not put in glass tubes or plastic toothbrush holders. It is best to have two toothbrushes for each person to use in turn, so that the toothbrush can be thoroughly cleaned and is conducive to sterilization.
  2. Everyone should have their own toothbrush. Mixing them is unsanitary and will cause diseases and bacteria in the mouth to infect each other.
  3. It is best to disinfect the toothbrush regularly, and you can put a few drops of soapy water on the bristles for mutual infection of diseases and bacteria.
  4. Do not soak the commonly used bristles and nylon toothbrushes in hot water, so as to avoid the bristles becoming soft and losing elasticity. Ordinary plastic toothbrushes are also resistant to high heat and will deform. The newly bought toothbrush can be soaked in warm water to clean it, and it can also make the hard bristles softer to avoid damage to the gums.
  5. If the toothbrush is used for a long time, the bristles gradually lose their elasticity, and the hair bundles are bent and scattered on both sides, which not only loses the cleaning effect, but also easily scratches the gums, and should be replaced in time. It is best to replace your toothbrush with a new one every month.
  6. When a cold, flu, or epidemic disease first recovers, you should put on another new toothbrush as soon as possible.
  7. If conditions permit, after each brushing, put the toothbrush in the disinfectant mouthwash for a while, and then take it out and dry it in the bedroom.

10 tips for protecting your teeth

  1. The measure of good toothpaste














First, the consistency should be appropriate, extruded from the hose into strips, which can cover the teeth without splashing. Second, the friction is moderate, and the tooth cleaning effect should be good, but the tooth enamel should not be damaged. The third is that the paste is stable, and the paste is not watery or hard during the storage period, and the pH is stable. Fourth, the drug toothpaste should maintain its efficacy within the validity period. Fifth, the paste should be smooth and beautiful, without air bubbles. Sixth, there is proper foam in the process of brushing, so that the suspension of food debris can be easily eliminated. Seventh, the aroma type and taste should be suitable. Eight is a big brand, trustworthy.​​

  1. Appearance standard of high-quality toothbrush

The general appearance of a high-quality toothbrush: the brush head is short and narrow, the handle is flat and straight, and the brush surface is flat and flush. No matter how cheap the plate-shaped large-head toothbrush is, some plate-shaped toothbrushes on the market, that is, those with large and wide brush heads, full and dense bristles, and small tuft spacing, are generally cheaper. Using such a brushing method is bound to cause certain damage to the teeth and gums, such as wedge-shaped defects of the teeth, gingival recession, exposure of the roots, and widening of the interdental spaces. In addition, the plate-shaped toothbrush cannot brush the back teeth due to its large head. After a long time, the food residues remaining in the back of the mouth will be fermented and corrupted under the action of bacteria, and then the teeth will be damaged. Because the damage to the teeth is a slow process, and the damage cannot be seen immediately, some people also think that the large head toothbrush is easy to use and save time, but they do not know the damage caused by a long time.​​

  1. Requirements for toothbrush bristles

The surface finish is good; the thickness is moderate, it is easy to deform if it is thin, and it is easy to damage the teeth and gums if it is thick, and the elasticity is not good; the grinding surface of the head is smooth.​​


4.Must grasp the correct brushing method

We must not only develop good brushing habits, but also pay attention to the method of brushing. If the brushing method is not correct, it can also cause disadvantages, the most common damage is tooth surface wear and gingival recession. Whether people can master the brushing method well depends to a large extent on the dexterity of the hands. Although everyone’s brushing gestures are clumsy, as long as they are sufficiently induced, most people can effectively use a toothbrush to clean their mouths. Children’s movements are slow and impatient, and they cannot cope with complex brushing techniques. They should be taught to use simpler brushing methods. For people with disabilities, a toothbrush with a modified handle design for easier grip may be required, or an electric toothbrush.​​

  1. How to test the effect of brushing your teeth?

From a preventive standpoint, plaque removal is the focus of oral hygiene. Because dental plaque is one of the common factors of caries and periodontal disease, if the dental plaque is removed, the prevention of caries and periodontal disease will be solved; at the same time, the foundation on which dental calculus is formed will be lost. . The standard for checking the effect of brushing is to see whether the plaque has been completely removed.​​

  1. When brushing teeth, scrape the tongue coating to remove breath and prevent gastritis

Did you know? Most oral bacteria are not on our teeth, but on our tongue and the lining of our mouth. According to domestic and foreign statistical data, the infection rate of Helicobacter pylori in the population is roughly 50%. This microorganism is the pathogenic factor of chronic gastritis and peptic ulcer, and has a tendency of mutual infection in a family. People with chronic gastritis should pay more attention to oral hygiene. Scraping off the tongue coating when brushing your teeth every morning is good for others and yourself.​​

  1. It is best to change your toothbrush after a cold

Some people suffer from colds or upper respiratory tract infections, which persist after treatment. In addition to the poor resistance of the individual, it may also be related to the toothbrush they use. If you don’t change your toothbrush, colds are less likely to heal, or more likely to recur. Therefore, the toothbrush should be placed in a ventilated and dry place. If you have had a cold, it is best to soak the toothbrush with disinfectant or replace it with a new toothbrush. In addition, it is best not to place multiple toothbrushes of family members together, but to place multiple toothbrushes, which is more conducive to the prevention and control of infectious diseases.​​

  1. Ten minutes after a meal is the golden time to brush your teeth

Generally speaking, 10 minutes after eating food is a critical period for dental care, because the pH value in the mouth drops from 6.8 to 4.5 at this time, and the acidity reaches a peak. If the teeth are not cleaned immediately at this time, these acidic substances will erode the teeth. The enamel on the surface forms decalcification, causing tooth decay. Brushing your teeth at least twice a day with a healthy toothpaste can continue to reduce the growth of harmful bacteria, which can help prevent tooth decay and the formation of tooth decay.​​

  1. Improper brushing is easy to get dental fluorosis

Although fluoride toothpaste can effectively prevent dental caries, it also has side effects. If used improperly, it can easily lead to dental fluorosis. The line between the caries-preventive effect of fluoride and its toxicity is very small. Excessive intake of fluoride can cause some spots on the teeth, which is dental fluorosis. In severe cases, the teeth can become yellow, the surface is rough, and it is easy to be damaged. Many Chinese and foreign scholars have found through scientific research that while dental caries are decreasing, the number of children suffering from dental fluorosis is increasing. The reason is that for children with insufficient swallowing control, accidentally swallowing fluoride toothpaste will increase the intake of fluoride, and excessive fluoride can easily lead to dental fluorosis. Therefore, for the use of fluoride toothpaste, there should be a correct familiarity, and master the correct method.​​

  1. Strengthen the health care of teeth

Traditional medicine advocates that knocking teeth and massaging the gums in the morning and evening are the most effective methods. Gently knocking the upper and lower teeth dozens of times every morning or after going to bed can promote the blood circulation of the teeth and periodontal tissues. Rotate and massage the gums to remove secretions from the gingival sulcus and periodontal pockets, which can improve blood circulation in the gums and improve the resistance of periodontal tissues, thereby preventing periodontal disease. At the same time to get rid of bad habits. Quit smoking, alcohol, eat hot and spicy food, remove residual crowns, residual roots, grind sharp cusps, and remove bad restorations to avoid chronic adverse irritation. The key to oral health care is in each person’s own hands, take care of your health, and wish healthy teeth will accompany you for life.
