Toothbrushing

Plaque is a biofilm, not just leftover food

Bacteria from the mouth can adhere to the teeth and organize themselves in a matrix: this is the dental biofilm. It reforms regularly, even when you don't see stuck food. Passing the strands disorganizes it and removes part of it. The minty sensation of toothpaste is no measure of this work, nor does a large amount of foam prove that all sides have been cleaned.

At the edge of the gums, the accumulation of plaque promotes an inflammatory reaction. The tissues may turn red and bleed more easily. Appropriate cleaning helps to improve plaque-related gingivitis, but established periodontal disease requires treatment. Brushing harder does not replace either a diagnosis or the professional removal of deposits which are no longer accessible to daily care.

Teeth lose and recover minerals

When certain bacteria use the sugars available in the mouth, they produce acids. These can lead to a loss of minerals from the surface of the teeth. Between these episodes, saliva contributes to the return to a less acidic environment and provides elements useful for remineralization. The problem arises when repeated losses outweigh the possibilities of repair.

Fluoride helps slow down demineralization and promote remineralization of beginning lesions. This does not mean that toothpaste can fill an already formed cavity: a tooth with a hole requires care. The frequency of sweet intakes also matters. Careful brushing is an important protection, but it doesn't make sipping a sugary drink all day harmless.

Why toothpaste and gesture are complementary

A brush can remove plaque without toothpaste, but it does not provide the fluoride expected in this routine. Conversely, putting toothpaste on your teeth without passing the bristles properly does not clean all surfaces. The two actions complement each other: the gesture controls the deposit, while the product leaves active ingredients in contact with dental tissues.

Sodium fluoride, stannous fluoride and other forms of fluoride are used in toothpastes. Some stannous fluoride formulas are also of interest against gingivitis or sensitivity, but the result depends on the complete product. First choose a suitable fluoridated toothpaste, then discuss a particular need with your dentist rather than systematically searching for the formula with the most promise.

Between the teeth, access changes the choice of tool

The surfaces between two neighboring teeth are difficult to reach with a conventional brush head. A brush can clean them when there is enough space; the wire is best suited for tight contacts. The available data supports benefits on gingivitis for several accessories, but the studies differ and their level of certainty is often low. It would be excessive to promise the same effectiveness in all mouths.

Dental jets can improve certain gingival parameters and facilitate maintenance when fine manipulation is difficult. They don't behave exactly like strands rubbing the tooth. A routine can therefore combine several tools depending on the space, without imposing wire, brushes and water flosser everywhere. The right choice is one that reaches the area without trauma and that you can use regularly.

Clean teeth are not necessarily whiter

Whitening toothpastes act mainly on surface discolorations thanks to their cleaning and abrasive agents. They do not have the same effect as a whitening treatment which modifies the pigments of the tooth. A naturally slightly yellow color does not mean that brushing is insufficient. Trying to erase it by rubbing harder risks increasing wear and sensitivity.

Charcoal or abrasive powders are not necessary to achieve good hygiene. If discoloration, bad breath or bleeding persists despite a regular routine, it is more useful to find the cause than to add brushing strokes. Brushing is a daily prevention tool; dental visits and necessary care remain its complements.
