Replacing Old Dental Crowns: Is it Necessary?

According to Dr. Terry Donovan, who is the chairman of biomaterials at the University of North Carolina School of Dentistry in Chapel Hill, the golden dental crowns do not need to be preventively replaced. As long as the dental crown is fitted perfectly, there should be no problems, and it is not necessary to replace them after 2 or 3 decades.

Dental crowns should be fitted in such a way that there are no open margins available, and there should be no dental decay present around the margins. Even though you do not need to replace periodically or prophylactically the dental crowns, it is of high importance that you go to the dentist regularly. The is going to perform a dental examination, and he will also check if the dental crowns are not deteriorated in any way and if they don’t pose any danger to your oral or overall health.

You need to understand that gold is not a corrosive material, so there is no problem from this point of view. However, the dental cement that is used to fuse the crown is dissolved by saliva after about 20 or 30 years. The big problem here is that as the dental cement dissolves, it allows the fluids that you consume to start seeping within those tiny gaps. This is how dental decay may easily occur.

Dr. Donovan also states that in case your dental crown is manufactured from porcelain which is fused to metal, and the porcelain has been chipped it is still not obligatory to replace the dental crown. Just go to the dentist and tell him to smooth out the edges of the chipped porcelain tooth. If this change is not that visible, and it does not cause you any inconvenience while eating or speaking, there is truly no need to replace your dentures.

Seniors in general become extremely anxious when their dentures crack or chip, because they believe they must replace entirely the tooth to function properly. If you cannot afford it just now, and there is also no need to replace it, just ask your dentist to perform reconstructive dental work.

As a patient, it is important to understand that dentists are generally keen on replacing restorations more often, because of obvious financial gains. They need the work, and since your dentures do not look as they used to, the dentist will suggest replacement. If the problem is not that complex, and your old dental crown can be saved through some polishing, filing and other dental reconstructive practices…you don’t have to worry about the exaggerated costs of crowns replacement.

For very bad gum contours and dental decay around the crowns, it is always good to get at least two opinions from dentists. While one dentist will want to replace entirely the crown, another one might advise some kind of restorative dental treatment which will preserve your old crowns and get you rid of pain and discomfort.
