Update: December 2018 There are probably few people who
really love dental treatment. The majority with
reluctance, anxiety or even fear go to the dentist outside
depending on age. Both adults and children want a doctor
rather, restored the tooth, and one would go home. However later
for some time it happens that the seal falls out. Why is that
what is happening and what needs to be done?
Common causes of loss of a seal
There are many reasons for the fact that the seal
falls out, and all of them can be divided into three large groups:
- medical errors;
- patient fault;
- features of the material used.
Let us consider in more detail each of them.
Unfortunately, one of the reasons why tooth fillings fall out is
is a medical error. Non-compliance may play a role here.
techniques of working with materials, lack of time for bona fide
work and lack of competence of the doctor, and sometimes
human factor (fatigue, inattention).
Due to the fault of the doctor, the seal may fall out in the following cases:
- violation of the rules of preparation of cavities – for reliable
retention of filling material in the tooth must be observed

- incomplete removal of tissues affected by caries – when during
preparation by the doctor due to inattention or because of fear of opening

- short time etching enamel and dentin – technique
total etching does not lose its relevance until today
of the day, although adhesive systems have been developed that do not require

the procedure allows you to remove the smear layer of dentin, removes
excessive inorganic from dentinal tubules, and also creates
roughness on the enamel, which increases the adhesion between the material
for filling and tooth. According to the rules, enamel is etched for 30 – 60 seconds, and
dentin – from 15 to 30 seconds. If you change the time down,
then it may adversely affect the quality of the restoration.
- violation of the adhesive protocol – the main purpose of making
adhesive into the cavity is to create a kind of “sticky” layer,
which allows the seal to firmly bond with solid tissues.
The main condition that must be met is
absolute dryness. Even a slight hit of saliva or water.

- fluid penetration into the cavity during work – sensitivity

- inadequate curing of the material – on the package to each

there comes its full hardening. And if the JRC (glass ionomer
cement) is less picky at work, then for curing
photocomposite required light exposure using an LED lamp
within 15-20 seconds. Therefore, the doctor must control the degree
the charge of the device, since the discharged lamp is not able to pass
the rays to the required depth, because of which the seal “seizes”
outside, but remains uncharted inside;
- the use of expired cements and photopolymers – not in vain
the manufacturer always indicates on the packaging the shelf life, since
This affects its physical properties. Some
unscrupulous dentists to save and not to throw out
expired material, make seals of it, hoping that they
will stand well. Sometimes this leads to the fact that after rendering
even a small chewing load, the patient returns with
complaints that he had a seal out of a tooth.
Sometimes there are situations when the tooth is destroyed so much.

however, warns him that treatment will be without guarantee, so
according to the testimony in this case requires a different type
treatment. Unfortunately, such fillings do not last for a long time, since there is no
conditions for their strong fixation in the cavity.
After reading the above points, you might get the impression
that dentists are always to blame for the fact that restoration happens
short-lived. Of course, unscrupulous doctors meet, however
most dentists value their reputation so they will not
make obviously bad fillings.
At the end of the treatment, the dentist always makes recommendations.

that these materials finally freeze only later

It is also necessary to brush your teeth regularly, because accumulations of plaque
lead to the fact that new carious cavities are formed. Also
bacteria that accumulate on the teeth can penetrate
micro spaces formed between the material and enamel and
cause relapses, i.e. re-infection of hard tissue,
leading to their demineralization and, as a consequence, caries.

the occurrence of microcracks on the enamel surface, which violates

Many materials used for fillings are universal, but there are
a large group that is used primarily for the front
or lateral group of teeth. Their main difference in particle size is: what
larger molecules, the higher the strength characteristics
however, low aesthetic qualities.
Macrofilled composites are suitable for the restoration of chewing
teeth, as the main requirement for fillings on molars is
resistance to high loads, and aesthetic qualities are moving away
into the background. If you perform the restoration on the side group

the likelihood that a seal will quickly fall out is increasing.
Loss of temporary fillings
For the manufacture of temporary fillings there is a separate group
