Temporary refers to a seal that the dentist puts at an intermediate stage of treatment. Usually such a seal is made of inexpensive materials, it is easily removed and is not intended for long-term replacement of a tooth defect. Many are interested in why it is impossible to immediately put a normal permanent seal, maybe the doctor wants to earn extra money? But believe me, this is absolutely justified stage of treatment, which, on the contrary, guarantees a careful approach and high quality of treatment.
Types of temporary seals
Temporary fillings are made from different materials, depending on the desired time and type of action:
- zinc sulphate based cements;
- cements based on zinc-eugenol;
- polycarboxylate cements;
- glass ionomer cements.
Why put a temporary seal?
In acute deep caries, do not put a permanent seal immediately, because the border between the tooth tissues and the pulp chamber, in which the neurovascular bundle is located, is so thin that the process can gradually turn into pulpitis . Then you have to treat and the channels of the tooth. For effective treatment of deep caries, the dentist at the first visit puts a medical pad that must be removed after a time, so a permanent seal is not immediately put on, but a temporary one is put. If the tooth under the temporary filling hurts a long time after the first stage of treatment, then it becomes a sign for the dentist to change tactics and speaks about the need for further treatment of the canals.
How do they put a temporary seal?
When pulpitis in the first visit, the doctor only opens the tooth chamber, and then puts there a temporary seal with arsenic, which is designed to kill an inflamed vascular bundle and further cleaning the canals. Modern pastes with arsenic contain anesthetics, so there will be no pain after such treatment. The service life of such a temporary seal is small - a few days, then the second visit to the dentist. Do not panic if a temporary filling has fallen out - you just need to rinse your mouth with water, because the concentration of arsenic in the pastes to remove the nerve is very low and can not lead to poisoning.
The first visit to the doctor with pulpitis or periodontitis can do without arsenic paste. Then the doctor under anesthesia removes the neuromuscular bundle from the tooth chamber and from its canals and conducts the medicamental treatment of the canals. In the canals are left turuns with antiseptics or medicinal substances, and the tooth is closed by a temporary filling after removal of the nerve. Many are interested in when you can eat after installing a temporary seal, so here's the time limit on which to refrain from food - just a couple of hours for the material to fully solidify.
With acute periodontitis, dental treatment can be delayed and more than 2-3 visits to the doctor. The doctor visits the first visit
At the second visit, the channels are once again processed and filled with therapeutic material. A temporary seal is placed from above. Why put a temporary seal on the second visit? To make sure that there is no more pus in the canals, which will be indicated by the absence of pain in the tooth. If the pain remains, the doctor again and again conducts medical treatment of the channels in several visits. And only when the channels are completely cleared, and there are no complaints, the dentist will be able to establish a permanent seal, both into the channels and into the cavity of the tooth.
