How to choose an electric toothbrush?

1. Choose the right type of toothbrush.

There are two types of electric toothbrushes: rotary type and sonic type. There is no absolute advantage or disadvantage between the two. I personally recommend starting with the sonic vibration type because the price is generally cheaper.

The rotary electric toothbrush uses a motor to drive the circular brush head to rotate. The advantage is that it is highly efficient in cleaning the tooth surface. The disadvantage is that it is less efficient in cleaning between the teeth, is noisy when used, and causes a lot of wear on the teeth.

Representative brand: Oral-B (actually all high-end Oral-B now are of the rotary sonic type, which uses physical vibration for double cleaning and has outstanding cleaning ability, but the price is also high)

There is an electrically driven vibration motor inside the sonic electric toothbrush, which allows the brush head to produce high-frequency swings perpendicular to the direction of the brush handle. When brushing your teeth, the high-frequency swing brush head not only cleans the tooth surface efficiently, but the mixture of toothpaste and water also A large number of tiny bubbles are produced, and the pressure generated when the bubbles burst can penetrate deep into the gaps between teeth to clean dirt.

Representative brand: Philips

2. Pay attention to the brush head.

First of all, you need to choose the right brush head size. I bought a large brush head before, but my mouth is relatively small, which made it very uncomfortable when brushing. I later changed to a smaller brush head before I could use it normally.

Secondly, we should pay attention to the quality of the bristles. The quality of the bristles is reflected in the amount of implanted bristles, whether they fit the tooth surface, the glossiness of the bristles, and the rounding rate of the bristles. However, it is difficult to see these parameters on e-commerce websites. You can Judge the quality based on the type of bristles. Low-priced ones mostly have cylindrical bristles, mid-range ones have triangular diamond bristles, and high-end ones have diamond-shaped bristles. The three bristles have different cross-sections and different efficiency in cleaning plaque. Choose according to your budget. Just fine.

Finally, please note: If the performance of the two products is not much different, choose the model with more brush heads, because the brush heads are too expensive! ! !

3. Pay attention to the speed.

For the rotary type, pay attention to the rotation speed exceeding 7,000 rpm. For the sonic type, pay attention to the vibration frequency preferably above 25,000 times. The higher the rotation speed and vibration frequency, the higher the price.

4. Pay attention to the cleaning mode

Try to choose a model with a variety of cleaning modes and adjustable intensity, which can be adjusted according to the user's sensitivity, but the price of this type of product will be very high .

5. Rich functions

Now entry-level products basically have a 2-minute timer function and a 30-second brushing zone change reminder function. Mid- to high-end models also have a brushing intensity feedback function. It will prompt you when it senses that you are brushing too hard to avoid damaging your teeth.

If there is not much difference in performance at the same price when purchasing, choose a model with these two functions.

6. Bluetooth and APP function

This function is mostly found on mid-to-high-end models. Many people think it is useless, but it is actually very useful. It will monitor your brushing behavior every time. By making records, it will evaluate and guide you on how hard you brush your teeth and whether it is standard, so that you can complete brushing more efficiently and standardly. Generally, models with this function are not cheap, and it is recommended to buy if you have a sufficient budget.

Enough about shopping, let me share a few tips for use.

1. First-time users should use warm water to adjust the softness of the bristles. It is recommended to soak them in warm water (below 40℃) before use.

2. Pay attention to the cleanliness of the fuselage and dry it in time. Because the humidity in the bathroom is high, it is easy to get moldy if you don't pay attention to cleaning.

3. Clean the bristles after each brushing. Put the brush head into water and turn it on. Shake it slightly to clean the foreign matter and toothpaste remaining on the bristles.

4. Separate the brush head and body after brushing, because there will be a gap between the two, and stains and long hair will remain in the gap if they are not separated for a long time.

5. The brush head should be replaced once every three months. On the one hand, it ensures the brushing effect and on the other hand, it ensures hygiene, because the bristles will have a lot of bacteria if they are in a humid environment for a long time.

6. Pay attention to battery maintenance. It is recommended to charge and discharge once in about half a year to extend the battery life.
