Problems after Amalgam Dental Filling

Dental fillings are done in order to restore a carious tooth to its normal form and function. Various materials have been used as filling materials. The most commonly used materials are composites and silver amalgam. Though the fillings are done for normal functioning of the tooth they may cause several problems.

Problems Associated With Amalgam Restorations

After dong the amalgam filling the patient may face the various problems. It is not always that the problems are there but some times either because of wrong diagnosis or because of poor handling of the material the problems can be there. These are
Secondary Caries -This is the most common problem with the amalgam fillings. The secondary caries are the caries or decay which forms after the filling is done and all the initial decay is removed. It happens because of the micro gaps which develops between the filing and the teeth which can cause micro leakage. This can be there if the filling is not doe properly or there is shrinkage after the setting of the filling due to poor mixing of the amalgam. If secondary caries are there then food lodgment is there and the patient may have hot ad cold sensation. Some times if it is deep then pain can be there. treatment is to replace the filling with the new one after removing the decay.

 

Marginal Fracture – Some times the silver filling fractures at the margin because it is weakest as there is no bulk and secondly the masticatory forces are quite high in that area. If the fracture goes unnoticed even then the symptoms are there like patients complaints of hot and cold sensation and some times pain. Treatment is to replace the filling
Tooth Fracture - Some times the filing is so big that the remaining tooth structure is less or the cavity preparation is not correct. This causes the fracture of the tooth. If the fracture occurs and the tooth is restorable the fractured tooth is restored but if the tooth is not restorable the crown is given on the tooth after doing the root canal treatme
nt. 

Pain after Dental Filling - After restoration if pain is there immediately or after a day or two then  there  is a possibility that the filling is high. In that case the selective grinding will serve the purpose but f the pain persists then it may be because of the deep cavity which is causing pain in the tooth. The treatment for this is to remove the filing and treat the tooth . If required then root canal treatment is done and crown is given

  • thanks for your reply , but i'm interested in this issue & i had another question :- is the secondary caries can be happened underneath the filling ( between the the pulp & the filling ) ? & if it can happened, will it appear in the x-ray & if not how it can be diagnosed & it will have the same symptoms in this case ? ..... sorry for a lot of questions & thanks a lot for you :)

  • Nora, Secondary caries are the caries which are there because of leakage between the filling and the tooth surface. It is due to faulty filling or it happens in old fillings. the gap develops between the filling and tooth surface causing the micro leakage and decay is there. it can be diagnosed clinically by probe as there is discontinuity between the filling and tooth surface and patient also gives the symptoms of pain and sensitivity. the diagnosis can be confirmed with xrays also.

  • Suraj, Some pain after dental filling is normal. It takes 2-3 days for filling to settle. If filling is close to nerve or in case of high point on dental filling, severe pain or pain occurs for long duration of time. If pain is severe, then you can visit your dentist for evaluation. If there is some high point on dental filling, then it can be smoothed and if dental filling is close to nerve, then root canal treatment may also be required. By the time, you visit your dentist, you can take pain meds for some relief and can avoid eating from side of filled tooth.
