Oral-B was formed by the merger of the original American oral care brand Oral-B and the German small household appliance brand Braun, and was merged into Procter & Gamble with Gillette in 2005. Oral-B and Philips are separated, and together they occupy half of the domestic electric toothbrush market.
 
Oral-B's expertise in the field of mechanical electric toothbrushes has been recognized by the industry, from "the first electric toothbrush to land on the moon" to "the brand most chosen by dentists in the world", from "American Dental Association (ADA) Professional Model" to "No. 1 Edison Innovation Award for Innovative Products".
 
In contrast to mainstream brands such as Takeoff Lipper, which use elongated brush heads similar to manual toothbrushes, Oral-B has always used a rotating round brush head design. The shape and mode of operation of this type of brush head means that it is aimed at cleaning a single tooth, which is more detailed than the normal long brush head that oscillates up and down, but at the same time requires higher user habits – precise operation and low fault tolerance.
 
At present, Oral-B's electric toothbrushes are divided into three series: 2D introductory cleaning, 3D professional care, and sonic care. Among them, the 2D series is the only pure mechanical electric toothbrush in the mainstream brands on the market, with a vibration frequency of only 7600 times/min, although it can strongly remove stains on the surface of the teeth in a short time, but long-term use has a large wear and tear on the teeth, and most of the 2D series do not have a 2-minute timer function, which greatly reduces the intelligent experience brought by the electric toothbrush, and is not worth recommending too much.
 
The 3D series adds front and rear vibrations on the basis of 2D rotation, and can achieve a maximum frequency of 8,800 vibrations per minute left and right, and 40,000 vibrations per minute forward and backward, which is the highest frequency electric toothbrush on the market.
 
The P600 (D16) in the 3D series can be used as the first choice for entry, with a comprehensive speed of 28800 times/min, which is lower than the usual vibration frequency of Oral-B, easier to adapt, and the price of 279 yuan is cost-effective. If you pursue higher cleaning ability, P600's advanced P2000 is the most recommended, with Oral-B main 48800 vibration frequency / min, the price of 379 yuan is really conscientious, compared with the popular models that often cost thousands.
 
As the world's first brand to launch Bluetooth smart electric toothbrushes, Oral-B has always been a leader in innovative technology in the industry. The iBrush 3D can connect the toothbrush to the Oral-B app on the user's mobile phone via Bluetooth to generate a personal oral care database and provide real-time visual guidance while brushing, with location detection function. This intelligent technology is the primary indicator to help electric toothbrushes reach the price of thousands of yuan, and it is also one of the standards to measure the grade of electric toothbrushes.
 
At present, the iBrush 3D series has several models from P4500 to P9000 Plus, the larger the number, the more functional accessories, the price is between 499 yuan and 2199 yuan, users can choose according to their own needs. Although the main intelligent technology can provide visual and all-round cleaning guidance, due to the actual operation, users need to actively click on the APP to connect and use, and the user is highly dependent, and friends who only pay attention to routine cleaning functions may feel that it is chicken, which is more suitable for people who are determined to correct improper brushing actions and want to develop professional dental care habits.
 
At present, the body and base of mainstream electric toothbrushes on the market have a waterproof rating of not less than IPX5, and there is no big difference in safety. Oral-B and Philips brush heads are the industry benchmarks, with a wide range of whitening, depth, sensitivity, tongue coating, etc., and a mature bristle cutting process that no Chinese brand can match. What is more convenient than Philips brush head is that Oral-B brush head is common to all products, and consumers do not need to compare complicated models when buying replacement brush heads, but the average price of 40 yuan is not low.
 
Due to the use of 3D vibration and large amplitude, the battery life is not strong, which has always been a common problem of Oral-B. With the normal frequency of use twice a day, two minutes each time, most of Oral-B's products can only be used for about a week, compared with the two-week start-up time of mainstream brands such as Liverpool, Oral-B is much inferior, and it is not very convenient for long-term business trips.
 
In addition, products below the Oral-B P4000 model are greatly reduced in terms of aesthetics and lightness. The fluorescent color color does not reflect the high texture, the bulky body is not easy to hold, and the portability is not satisfactory, even the beautiful appearance of the iBrush 3D series, its body size is not as slim. Of course, this is also the most common defect of mainstream brands, but fortunately it does not affect the cleaning efficiency of the product.
