How does plaque form in teeth,how to remove them with electric toothbrush
Plaque is a microbiome that sticks to the surface of teeth or other soft tissues in the mouth. It usually consists of a large number of bacteria, intercellular material, a small number of white blood cells, exfoliated epithelial cells, and food scraps.

The question is, how does plaque form?
Stage 1: acquired membrane formation
The salivary glycoproteins in the mouth are a substance found in the saliva of everyone. When it comes in contact with a tooth, it can attach to the enamel surface and form a membrane-like substance, called an acquired membrane. It provides the substrate for the initial adhesion of oral bacteria and creates the conditions for the formation of dental plaque. It has been proved that gingival sulcus is the first place to form the acquired membrane of teeth.
Stage 2: bacterial attachment
A large number of research data confirmed that the first bacteria attached to the dental surface are streptococcus group and streptococcus salivary. The bacteria grow on the surface of the acquired membrane and can produce acids and deposit glycoproteins. Blood group streptococcus and streptococcus mutans can synthesize glucan and form plaque matrix together with the deposited glycoproteins, creating the basis for the formation of plaque. When the acquired membrane is formed on the tooth surface, bacteria attach to it very quickly, indicating that the attachment rate is fast.
Stage 3: plaque formation
A large number of plaque bacteria attached to the tooth and gingival junction grow, develop, reproduce and die on the acquired membrane, and carry out complex metabolic activities in it.
So how do you know if you have plaque? Dent dental hygienist USES professional plaque display solution and applies it to the teeth with professional tools. After a certain period of time, we can test whether there is plaque on the teeth.
For dental plaque testing, the following cleaning work has certain removal effect:
1 brush your teeth
Brushing teeth is the basic measure to remove plaque, but also the most basic method. If you brush your teeth properly, the amount of plaque on the tooth surface can be greatly reduced, so we must develop a good habit of brushing every morning and evening, and master the correct brushing method.
Tips: as the number of times of use increases, the tooth brushing will gradually wear out, thus reducing its effect, so it is recommended to change a new toothbrush every 3 months or so.
An electric toothbrush can remove seven times as much plaque in two weeks as a manual one.
Gargling is a method of cleaning the mouth. It mainly USES the impact of liquid flowing in the mouth to remove food residue, but it cannot remove plaque. Mouthwash is made by adding a few ingredients to the mouthwash. Mouthwash can reduce the formation of dental plaque, reduce the incidence of caries and periodontal disease plays a role, but also can not be abused.
3 Dental floss
Brushing alone is not an effective way to remove plaque from the adjacent tooth surface (the gap between two teeth), so other accessories are needed. Dental floss is one of them. Dental floss can effectively remove dental plaque from adjacent teeth, prevent periodontal diseases and adjacent caries.
4 brush clearance
The interdental brush is composed of bristles and handles. It has various designs and specifications. It can be selected according to the size of the tooth space to effectively remove dental plaque on the adjacent tooth surface. Choose the right size gap brush according to your teeth
Because of simple brushing, it is hard to avoid thorough cleaning. Regular cleaning of teeth once or twice a year can effectively remove dental calculus and plaque attached to the teeth and protect oral health. If there is already tooth pain, sensitivity and other problems, suggest to see a dentist as soon as possible, listen to the doctor's advice and treatment, so as not to delay the disease.
