What's the use of a tooth flush? Is it an IQ tax?

Just brushing our teeth every day can only clean up about 60% of the food residues in our mouth, leaving a lot of residue and tartar accumulation in the gap between the teeth and the gingival groove. This leads to the fact that although we brush our teeth, we still face a large risk of disease.

The existence of dental flushing device can improve the internal environment of the oral cavity and play the role of cleaning teeth at any time. It is suggested that food residues remain. So, the existence of a toothbrush is not an "IQ tax," but a second cleaning on top of a good brushing.

    Can you use dental floss instead of a dental flush?

According to scientific evidence, people who wear dental flushes and floss have a 50 percent greater reduction in gingivitis than those who floss alone.

In my opinion, in fact, the relationship between the two is complementary to each other, rather than replacing the relationship, dental floss can not fully clean the food residue in the teeth, combined with the teeth flushing device can clean the teeth more clean!!

Who's going to use a tooth flush? Do I have to use a tooth flush?

Blunt teeth at first mainly for some crowd of oral diseases such as tooth decay, gingivitis, periodontitis and other oral diseases patients and dental implants, dentures, orthodontic orthotics, behind gradually became a daily auxiliary toothbrush oral cavity cleaning tools, family has been very popular in foreign countries, and only in the domestic began to understand by the public is the last two years, So think of the toothbrush as a daily cleaning tool like a toothbrush. The sooner you use it, the sooner you can prevent oral disease.

For pulsed water flow, pulse and water pressure are the key mechanisms to exert the cleaning effect of the pulsed tooth flusher. The combination of the two on the tooth surface and periodontium can produce the alternating effect of pressure and decompression. Water rushes into the teeth and inside the gingival crevices during the pressure phase, while the pressure phase facilitates the smooth outflow of food debris and bacteria.

As a result, pulsed flushes are more effective at removing plaque and food debris and massaging gums than constant water pressure (water guns). Early studies have shown that a pulsed high-pressure water stream at a pulse rate of 1200 beats /min is three times as effective as a non-pulsed water stream. When the water pressure is medium or high, the effect is similar if the water pressure is perpendicular to the tooth surface or along the tooth surface (towards the gingival crevices). However, considering that the water pressure is more painful, it is suggested that the water pressure is perpendicular to the tooth surface.

At present, almost all the articles have not mentioned the appropriate amount of water pressure, and there are few domestic researches in this field. Therefore, I searched extensively in foreign language, and finally found some evidence. In fact, as early as 1969, Bhaskar et al of the US Army Dental Research Institute did related research:

1. Gingiva can withstand up to 160PSI water pressure for 30S (limit condition), once exceeded, irreversible damage will occur

2. The maximum recommended pressure is 90PSI for undamaged oral tissue (which is consistent with a document published by the American Association of Epidemological Periodontiums [4]), and 50 to 70PSI for existing oral tissue with inflammation and ulcers.
