When brushing your teeth how can kind of toothpaste to waste a bit less?

Answer:
a little less crowded , brush over the time to change brush position. I am referring to the location inside the toothbrush in the mouth ah.
Answer:
main purpose of brushing the teeth is to remove the plaque surface in order to avoid tooth decay or other dental diseases. Many people think that only the toothpaste produced by bubbles, in order to help clean teeth, brush your teeth be sure to use toothpaste to brush the teeth clean. In fact, the best cleaning is a thorough clean using a toothbrush to remove plaque, toothpaste is only an auxiliary supplies, even without toothpaste can also make personal oral hygiene.
healthy teeth are coated with enamel,
for grinding food and the protection of the internal teeth. The main ingredients of the compounds of calcium. Toothpaste in the main role of a clean, and not become a bubble interface active agent, but the so-called abrasives (abrasive). Common are calcium carbonate, magnesium carbonate, aluminum hydroxide, titanium dioxide and so on. The main function of the abrasive, that is attached to the enamel on the removal of dental plaque, as long as regular removal of plaque, the enamel was acid out of the role of calcium and phosphorus, can be mineralized by the saliva through (remineralization) the process of re-added, while the to enamel regain its original strength. However, if the abrasive particles too thick, and may also cause the enamel to wear, choosing toothpaste should pay attention to the thickness of abrasive particles, to avoid using too coarse abrasive containing toothpaste.
is currently the most commonly used fluoride-containing toothpaste, fluoride contribute to the maintenance of robust enamel. Typically, in toothpaste with stannous fluoride (fluoride or Fluoristan, SnF2), sodium monofluorophosphate (Sodinm-monofluorophosphate, Na2PO3F) or sodium fluoride (sodium fluoride, NaF) form, its role is: to replace the enamel hydroxyapatite Some of the hydrogen in the base (hydroxy group), to form a stronger fluoroapatite acidic compounds; In addition, inhibiting the ability of bacteria produce acid.
some toothpaste claimed to be able to prevent periodontal disease, and the present study found that lead to periodontal disease pathogens, and can not be completely eliminated by drugs, for a strong resistance to antibiotics and difficult to eradicate. Therefore, anti-bacterial toothpaste on the market can usually only reduce the amount of bacteria, but not complete elimination of periodontal pathogens. The other common aromatic additives, eliminate bad breath, but a limited effect.
anti-sensitive toothpastes tooth dentine can be closed within the micro-channels to reduce tooth sensitivity. Different brands with different chemical composition, for example, Potassium Nitrate, Strontium Chloride, or Hydroxyapaptite.
are many kinds of toothpaste on the market, we can choose their favorite flavor of fluoride toothpaste, but the most important thing is every day must be a thorough brushing before going to bed in order to achieve the purpose of preventing tooth decay. But as long as the small amount of toothpaste the size of a pea or a thin layer is enough.
