On these sides you can get answers to questions frequently placed from the range of the tooth health.


Why do my gums bleed during brushing?

Gums or gingiva is the fleshy tissue that covers the jawbone around the base of ones teeth. This tissue is exposed to external factors and various changes resulting from certain physiological and pathological conditions. Disturbingly, a majority of people have experienced gingival bleeding during brushing without attaching adequate importance to it. Bleeding is always a sign that there is something wrong, i.e. that the vascular system or blood vessels somewhere in our body have been compromised. Our body warns us of these deficiencies, which we simply ignore.


The most frequent causes of gingival bleeding are chronic gingivitis and periodontitis due to inadequate oral hygiene. For more information about these chronic diseases and proper oral hygiene, see AIR FLOW on our website. Less frequent causes include the increased tendency to gingival bleeding during puberty and pregnancy caused by hormonal changes. Conditions that lead to vitamin deficiency (especially vitamin C deficiency - scurvy, and others as well) can result in gingival bleeding. Gums can be sensitive and bleed in febrile conditions such as acute inflammation of upper airways (inflammation of the pharynx, nose, larynx, tonsils).


We should improve oral hygiene and remove all possible causes of bleeding, both local (tartar, plaque, old fillings) and systemic (vitamin and nutrient deficiency, control of chronic diseases).


I have bad teeth although I brush them several times a day. Why?

Caries is a disease with several risk factors whose interactions lead to the decay of hard dental tissue. These factors are oral bacteria, nutritive substances these bacteria use for their metabolism and reproduction, and time. Therefore, all these factors should be minimized in order to prevent caries. Generally, a set of measures for fighting all three of these causative factors at home is called oral hygiene. First, we must explain that adequate oral hygiene does not include brushing alone, but a number of other measures and procedures. We should also emphasise that oral hygiene today implies a different approach to brushing ones teeth than that used even a couple of decades ago. The reason lies in significantly changed dietary habits, primarily in the system and the consistency of the food we eat that make it more difficult to keep our teeth clean between two brushings. This food is very sticky and easily adheres to dental surface, where it remains long enough to start the processes that finally lead to demineralisation of hard dental tissue and development of caries.


Therefore, a toothbrush and toothpaste are no longer sufficient to keep our teeth healthy


Visually, it may seem that we have removed all the plaque by brushing. However, this does not mean that we have removed all bacteria from dental surface. In addition to brushing, we should also floss. It helps us clean the areas between the teeth with food particles that we cannot remove with a toothbrush. Currently, special interdental toothbrushes are also available. We should also mention the mechanical cleaning of the tongue. After brushing ones teeth, we should also brush the tongue to remove all food residue and bacteria that could lead to the above mentioned conditions and diseases. There are also various antiseptic solutions (mouth washes) that reduce oral bacteria and contribute to the improvement of oral hygiene.


How can I whiten my teeth and is this harmful?

Currently, you can buy many whitening agents – from ordinary toothpastes to whitening agents for professional use. First, one should mention that toothpaste can neither whiten teeth nor remove tartar. It can only remove spots from the dental surface. Whitening of teeth is usually done in the dentist's office with oxidant-containing preparations (e.g. carbamide peroxide), and the procedure is painless. The preparation is applied with an individual spoon to each tooth and left to stand for some time (from several minutes to half an hour) depending on the concentration of the active substance in the preparation. After that, the preparation is rinsed off, and the teeth are protected with a fluoride preparation. This can be done at home in a similar way. Your dentist will apply the preparation, however, its concentration is much lower and the treatment lasts longer.


So far, we have talked only about whitening of all teeth, but individual teeth can be also whitened, especially those that have lost their natural colour (i.e. became dark) due to a specific treatment (devitalisation, removal of the dental nerve). Similar preparations are used, however, they are applied to the interior of the tooth. This procedure is called inner whitening.


If whitening agents are applied carefully and professionally, whitening is not harmful for the health of your teeth!


I got a toothache 4 weeks ago while eating. It is a back tooth with a new white filling. I have ignored it so far, because I was told that it takes some time for the tooth to adjust to the filling. The pain does not last long, but it is unpleasant. Please tell me if I should be patient or is this something serious?

Your problems are most probably completely benign and they are related to postoperative hypersensitivity. It results from microphysical changes in dental substance after the application of composite (white) filling. These discomforts will subside within a month to two. If they persist, we shall replace the filling after tooth desensitisation.
