Tooth cleaning, dental floss, tooth brushes and Co.
So, what does this technique using different instruments look like?
Contrasting with this, interdental brushes are gentler on the gums. They also have the advantage of opening up when being pulled back between teeth, a bit like an umbrella, fitting nicely into the anatomy of the spaces between the teeth, removing additional plaque in these areas. This is the main advantage of interdental brushes for cleaning between the teeth, as when these spaces are not cleaned there is greater chance of tooth decay or periodontal disease setting in. Dental floss is only recommended for maintaining dental hygiene in cases where interdental brushes cannot fit between teeth.
A further recommendation from our dental hygienists to improve dental hygiene: don’t use mouthwash. These have the disadvantage of mainly removing “good” bacteria, giving the “bad” bacteria more space to multiply. A tongue cleaner can help to remove deposits on the tongue. This should be done carefully and gently as there are a variety of useful glands present on the surface of the tongue e.g. glands that send taste signals to the brain.

All of these different products can only help when used properly. Correct use of a standard manual toothbrush (not electric) is with the so-called ‘modified Bass technique’. This involves using soft, circular-motions, also working backwards and forwards over the tooth and gum. Once one area has been covered using this circular brushing, the bristles of the toothbrush are flicked down the surface of the tooth away from the gums.
This removes any loosened plaque from the interdental spaces, which can finally be flushed away from the mouth using water.
The best tooth-cleaning time
As dentists and dental hygienists, we are often asked about this. A recent study has scientifically proven that bacteria amass over a 24-hour period, and only then build up a matrix structure (biofilm) to carry out their work eroding away the enamel with the acid bi-products from their metabolism. This process causes minerals to be extracted and the first steps of tooth decay (caries) start. If patients are successful in repeatedly destroying this bacterial biofilm using the right dental care, then the bacteria are never able to further develop this demineralising effect. It is for this reason that, strictly speaking, it doesn’t matter when the teeth are cleaned. As people are creatures of habit, it may be beneficial to get into a routine of cleaning teeth at a specific time. The ideal for this is “before bed”.
By brushing with the proper technique just once, then that’s a big step in the right direction for preventing tooth decay and periodontal disease. The emphasis here, though, is on “proper”. If the proper technique is not achieved, using toothbrush, floss and/or interdental brushes, then even brushing multiple times per day will not protect against tooth decay. Generally, it is recommended to wait thirty minutes after eating before brushing your teeth. Another important tip for proper cleaning and to ensure long-term dental health: use a toothbrush with a smaller head, and regularly change your toothbrush for a new one.
Frequently asked questions
When should I brush my teeth, and how often?
Very simple: done properly, once every 24 hours. But what does “properly” mean? It is worthwhile to ask about this during your next dental hygienist appointment.
It is certainly not true that cleaning more times in the day is better. It is enough to destroy the bacterial biofilm just once every 24 hours. People normally find it easier to carry out this type of task as part of a routine. Many people tend to find that this is easiest every evening, before bed.
What type of toothbrush is better for me: electric, or a standard manual toothbrush?
An electric toothbrush can help to better remove plaque in hard-to-reach places where plaque can hide, and to ensure that the movements of the small toothbrush head are circular. Electric toothbrushes, and even ultrasonic toothbrushes are not, however, any guarantee that you will not suffer from tooth decay. Where patients are able to clean their teeth daily, applying gentle pressure with the toothbrush, mainly concentrating on the area of the gum line and tooth surface, combined with using dental floss or interdental sticks, then generally nothing should happen to the teeth.
Am I cleaning properly when the toothpaste foams up lots?
No, foaming of the toothpaste does not indicate the you are cleaning your teeth properly.
Am I cleaning my teeth wrong if I have exposed tooth necks?
It can happen that you are not able to clean both sides to the same extent due to the hand you use to clean your teeth with. People have a tendency to clean one side more than the other. This can cause gums to recede and tooth necks to become exposed. The reason pain occurs is that the enamel, which protects against exterior stimuli, does not completely cover down to the dental root. For this reason, if the gums recede, then dentine becomes exposed. Dentine cannot itself provide adequate protection against stimuli such as the cold or heat. This leads to pain induced by the nerves which form a network inside the tooth.
Should I use dental floss or interdental brushes?
In the majority of situations, using interdental brushes is recommended. They have the advantage of preventing damage to the gums, as is often the case when pulling floss down between the teeth. Additionally, the bristles on the interdental brushes are able to fold back out in the spaces between the teeth, fitting nicely into the anatomy of the spaces between the teeth, removing additional bacteria. Dental floss mostly has advantages in particularly tight spaces between the front teeth of the lower jaw.
