When to change toothbrush after being sick?

should you change toothbrush after a cold? You may have heard from your dentist or other sources that it is important to change your toothbrush after a cold. It is said that people who are constantly sick don’t need a toothbrush. We recommend that you change your toothbrush after being sick, as a safety precaution, regardless of the severity of the illness. Even if the odds are low, bacteria attached to brushes can stay, multiply, and migrate, increasing your chances of re-infecting something. Brushes (and brush heads) are usually cheap, and it’s better to be safe than sorry.

What’s wrong with not replacing your toothbrush?











  •  Reinfection

Whether it is a cold or a fever, the viruses and bacteria in the oral cavity will come into contact with the toothbrush, so it is necessary to replace the toothbrush after getting sick to prevent the residual virus from “returning” to infect you.

  • The gums bleed easily

When the toothbrush head is damaged, continued use not only cannot remove the dirt and bacteria on the teeth, but if you brush your teeth with force, it will further stimulate and compress the gum tissue, resulting in inflammation and bleeding of the gums, and the health of the gums will also be greatly affected.

  • Plaque and calculus appear

If the bacteria on the teeth are not properly removed, in addition to causing calculus and bad breath, there will also be periodontal disease. At this time, the alveolar bone will also be damaged, and the teeth will become loose after losing their support. , resulting in tooth loss. And if periodontal disease is too serious, it will also induce cardiovascular and diabetic diseases, so brushing your teeth carefully is also one of the ways to maintain your health.

  • Reinfection

Whether it is a cold or a fever, the viruses and bacteria in the oral cavity will come into contact with the toothbrush, so it is necessary to replace the toothbrush after getting sick to prevent the residual virus from “returning” to infect you.

4 Situations When It’s Time to Replace Your Toothbrush

  1. Found discoloration at the root of the bristles

The bristles at the root of the toothbrush are dense. If the toothbrush is not cleaned carefully after brushing, dirt and toothpaste will easily remain on the root, which will lead to the growth of bacteria and affect oral health.

  1. Change when you are sick

Whether it is a cold or a fever, the viruses and bacteria in the oral cavity will come into contact with the toothbrush, so it is necessary to replace the toothbrush after getting sick to prevent the residual virus from “returning” to infect you.Although there is a saying that your immune system produces specific antibodies to fight the virus that caused your infection. These antibodies are still there and protect you from getting the same virus again.

but your family or friends’ toothbrushes are very close to your toothbrush, you need to replace the toothbrush in time, because they do not have antibodies in their bodies. In addition, we strongly do not recommend placing toothbrushes close together or sharing toothpaste, as this may spread many other diseases, not only oral related.

  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.

But just changing your toothbrush isn’t enough, cleaning your toothbrush is important, and it’s easy to do.
  1. Clean the toothbrush Please rinse thoroughly with tap water before and after using the toothbrush. Soak your toothbrush in an antibiotic mouthwash if you have a systemic condition or an immune dysfunction.
  2. Deep cleaning There are a variety of toothbrush sanitizers on the market, and UV toothbrush sanitizers can also be used to kill the microbiome.
  3. After properly storing the toothbrush, do not put the toothbrush back in the cabinet or drawer. The toothbrush should be placed upright in a dry place (such as a rack or cup) to dry.

2.Electric toothbrush buzzing when charging

People who use an electric toothbrush for the first time are frightened by the sound of the electric toothbrush, because it will make a “humming” sound during its work, which makes their head hurt. manage? When the sound of the electric toothbrush you use is relatively loud, everyone will guess whether the electric toothbrush you bought is irregular, so how loud is the electric toothbrush normal?

When the sound of the electric toothbrush is too loud, you can lower the gear. Generally, the electric toothbrush is divided into two or three gears. You can choose the electric toothbrush with the lowest gear to brush. If the noise of the electric toothbrush in the lowest gear is too loud, you can replace it with an electric toothbrush. Generally, a big brand electric toothbrush is selected. It has noise reduction treatment. Technology, the process of using an electric toothbrush will not clean to too much noise.

Some electric toothbrushes are not very loud at first. After a period of time, the sound suddenly becomes louder. It is necessary to consider that there may be damaged parts inside. You can find after-sales inspection and maintenance of electric toothbrush brands.

The normal sound of an electric toothbrush should be below 50 decibels. Among them, about 40 decibels of electric toothbrushes are generally acceptable. Some electric toothbrush brands have done a good job in noise reduction. to what sound. If the sound of the electric toothbrush exceeds 50 decibels, it is recommended to replace it in time.



ELECTRIC toothbrush keeps buzzing on charger

If the ELECTRIC toothbrush is charging, it will beep on the charger. You don’t need to do anything unless the noise is loud or your device has stopped working.

But many users have different opinions on what the beeps actually mean. Some users have noticed that the beeps often indicate some problem with the product itself – some of which are listed below:

  1. There may be a problem with the charging base

Your problem might be with the toothbrush’s charger, not the toothbrush itself. Your charger might not be able to supply enough power to your device, or there might be a problem with its internal wires.

If your charging base is not working, you have the following options:

  • You can contact the toothbrush manufacturer or supplier for repairs.
  • You can buy a new charger to replace.
  • Your toothbrush may need to be reset

If the toothbrush beeping is unbearable for you, try a hard reset by:

  1. Put the toothbrush base on the charger
  2. Press and hold the strength button and the power button for about five seconds
  3. Wait until you hear three beeps and the light turns green

Now, go away. If your toothbrush stops beeping (or at least diminishes), you may have solved your problem.

  1. The toothbrush head is not in the correct position

If you don’t place the head of the toothbrush in the correct position, the sensor can get confused and therefore beep. Remove the toothbrush head and put it back in place. If you’re sure your head is correct, try performing a hard reset.

  1. toothbrush head does not match

As mentioned earlier, ELECTRIC’s toothbrush heads are replaceable. With new products on the market today, while the new brush head may also fit your toothbrush, it may not fit the product’s sensor.

Use non-original brush heads on your toothbrush, as this may affect the overall performance and functionality of the device.

  1. Toothbrush screw loose

If your electric toothbrush suddenly starts humming while charging, it’s likely that the actuator screw on the motor needs to be tightened.you’ll need to take on the job of completely disassembling your electric toothbrush, or learn to accept the sound.

If you are still under warranty, you can return the toothbrush to a repair agent for replacement. There are some electric toothbrushes that make it easy to find the actuator screw, but this is rare. Check with your manufacturer using their website or service manual to see if this is possible. If it is, it usually fixes the humming right away.

  • electronic failure

While not as common as a loose actuator screw, faulty electronics can set off a chain of failures. Also, although unlikely, water damage to the bottom of an electric toothbrush could damage it so much that it starts to behave strangely. From turning it on in the middle of the night to triggering a charging “beep” for no real reason or need, a lot of things can go wrong. Repairs are usually not economical and in most cases require a complete replacement.

  • Find multiple units

Most electric toothbrushes and their charging stations are fine within range of each other, but in some cases, conflicts can arise. Check if your cordless electric toothbrush is near other brands. Separate the two to isolate them as possible causes.

Sometimes interference can cause a “hum”-like tone. This test is quick and easy and only affects some users. Keep in mind that other wireless electronic devices and electronic devices plugged into the same outlet can also cause interference.

  • Test different sockets

Try charging the electric toothbrush from a different outlet. Anything that has electricity, such as an electric shaver, electric toothbrush, etc., can hum if there is a leak.

Try plugging in a different charger and see if its sound is amplified by the faulty circuit to confirm the problem, if a different outlet gives you no issues and no loud sounds.

  • Fully discharge your electric toothbrush

Before giving up your electric toothbrush, try to drain it completely. Use it until the battery is completely dead, then let it rest overnight.

Charge it up again in the morning and see if it buzzes like before. One thing we should be aware of is that if your charger is humming from the start, it’s most likely due to vibrations inside the device. There’s nothing to worry about – all you need to worry about is if the sound is intermittent or starts suddenly.

  • Sudden buzzing is bad

If your electric toothbrush suddenly starts humming very loudly, don’t keep using it. It could short out internally and then create a fire risk. Even if the internal oscillations have gotten loud enough, it’s just a sign that you’re about to replace it. See if there is a replacement charger, if not, replace the entire unit.

  • When to stop using an electric toothbrush

When an electric toothbrush exceeds a safe operating point, it stops charging or starts making excessive noise.

If the fault causing the noise cannot be repaired or the repair cost is too high, replacement is not worth it. This is when you need a new toothbrush.

If the noise is small, you can consider buying a sonic electric toothbrush. The sound of a sonic electric toothbrush will be smaller than that of a rotating vibration type.

Today’s electric toothbrushes can be roughly divided into oscillating electric toothbrushes and mechanical rotating electric toothbrushes.

Both electric toothbrushes are not identical in function and noise.

In terms of function, I saw a dentist on Zhihu who gave a reference to the literature, saying that the rotary electric toothbrush is cleaner than the sonic vibration type, because the rotary type can completely wrap the whole tooth and can remove the gingival sulcus. and tooth surfaces are cleaned. However, the cleaning between teeth may be weak, and at this time, it shows the ability of sonic vibration.

For the sonic oscillating electric toothbrush, we only talk about the type with obvious bristles oscillating. The bristles are electric toothbrushes that swing up and down, similar to Panasonic’s electric toothbrushes, mainly simulating the Pasteur brushing method, which is very powerful for cleaning the gingival sulcus. The bristles are swinging from side to side, such as Philips, today, which simulates the Roche brushing method, which has a great effect on cleaning the gap between the teeth.

In terms of noise, the noise of the mechanical rotary type is correspondingly larger, mainly because most of the mechanical rotary type uses hollow cup motors. The interior of the hollow cup motor is operated by the motor equipped with an eccentric wheel, and the vibration frequency of many electric toothbrushes will be set relatively high. If the vibration frequency of the hollow cup electric toothbrush is higher, if the internal vibration reduction treatment is not performed, the noise will be high. bigger. Moreover, the cost of vibration reduction treatment is much more expensive than replacing a better magnetic levitation motor, so electric toothbrushes with hollow cup motors on the market are generally noisy.

And electric toothbrushes have four key advantages over ordinary manual toothbrushes:

  1. Stronger cleaning power and higher cleaning efficiency. The electric toothbrush has a vibration frequency of tens of thousands of times per minute, which is far stronger and more efficient than manual toothbrushes. Best of all, an electric toothbrush removes stubborn tartar and plaque, which is basically impossible with a manual toothbrush.
  2. The tooth gap is cleaner, and there is no blind spot for cleaning. The electric toothbrush not only has strong cleaning power, but also the vibration frequency can drive the impact of the water flow, so that the bacterial residues in the tooth gap can be effectively cleaned.
  3. The cleaning force is even and controllable, and there will be no manual toothbrushes. The teeth that are easy to be strained will have a lot of strength, and the molars inside the oral cavity will not be able to exert force, resulting in unclean brushing.
  4. The brushing time can be managed. The electric toothbrush provides a 2-minute stop and a 30-second zone change reminder, which can more reasonably allow users to develop the habit and awareness of scientific cleaning.

Who is suitable for an electric toothbrush?

Although the comparison between the advantages and disadvantages of electric toothbrushes and ordinary manual toothbrushes is very dominant, but from my own experience of using electric toothbrushes over the years, people with the following characteristics are not recommended to use electric toothbrushes, it is best to use manual toothbrush honestly or listen to a dentist suggestion.

The first category: elderly people aged 60-65 years old and children under 10 years old have a relatively high risk factor for using electric toothbrushes.

The second category: users with severe periodontitis, loose teeth, and frequent gingival bleeding will inevitably increase the risk of tooth injury when using electric toothbrushes. How to distinguish such users? In fact, serious dental problems must be accompanied by severe pain, weak bite, loose teeth, frequent bleeding, purulent gums, swelling and other characteristics. In this case, you need to seek medical attention in time. If the degree is not so serious, you can use a high-quality electric toothbrush with confidence. !

The third category: users who have recently received dental treatment need to pay attention to the use of electric toothbrushes under the advice and guidance of doctors, such as root canal treatment, medical whitening, etc. Generally, electric toothbrushes can be used, but they need to be cautious and try their best to use electric toothbrushes. Use after recovery period.

Electric toothbrushes generally take 24 hours to be fully charged. As long as you make sure that you have enough time to use them, you can use them. If you have enough time to use them and the use time is very short, there may be a problem with the machine. Just use it.

Because the frequency of use of electric toothbrushes is generally twice a day, one time is two minutes, and a full charge can be used for about 28 days. This is the charging time of most electric toothbrushes on the market, but according to the number of personal use, the actual use time of a full charge It’s about three weeks.
