Problems with fillings do not depend on how long ago you put them on and what material the specialist used. After a certain time, as well as due to a number of other circumstances, the appearance of the seal may not change for the better.
There are several reasons for the darkening of the filling. Maybe the dentist “felt sorry” for you and did not clean the entire surface of the tooth, and caries continued its “dirty deed” in the untreated place. The reason for this may be insufficient oral hygiene or an untimely whitening procedure.
Someone can shrug their shoulders and say: “Nonsense, I have had a filling for 10 years and nothing. All these are inventions of dentists, so as not to be left without clients!” This is not true. Think about it, everything that surrounds us has an expiration date. The materials from which the fillings are made also have it. Add to this the extremely aggressive environment of the oral cavity. Constant humidity, temperature fluctuations, the presence of acids and salts, mechanical stress, active microflora. What will happen? The service life of the seal is from 4 to 5 years. And this is provided that it was put by a highly qualified specialist who gives a guarantee for his work. Yes Yes! This also applies to high-quality fillings.
You should visit a doctor if:
filling darkened
do you feel pain
roughness and discomfort in the mouth appeared
like to drink too hot or icy water
By the way, old fillings (due to the imperfection of the material) may well be toxic. Modern materials are devoid of this “shortcoming”. And one more piece of advice. Do not go to different doctors, rushing from one extreme to another. It is better to choose a permanent modern clinic, only in this way you will receive exactly the help you need, there will be no unnecessary pain, only modern methods and materials will be used, with a guarantee of high-quality treatment.
