Dental work...?

I am getting 2 crowns and after my first appointment (about 7 hours later) I got a horrible sore throat and ear infection on the same side as the teeth that are being worked on. I went to my dr and he put me on Ceftin. I did not tell him about the crowns because I did not think the two occurances were related. Are they?? I am still not feeling well after starting the antibiotic. Thanks for any help.

Dental work...?
YOU MIGHT BE ALLERGIC TO THE METAL OF THE CROWNS OF THIS MAY JUST BE PURELY COINCIDENTAL.
Reply:I don't think it is an allergy to the the crown (read excerpt below), even if it is, you would have different symptoms.... maybe you could go to a different doctor and tell them about the crown this time. Whatever you have is likely just resistant to the Ceftin or it has not had time to work.





I know of no situation in which a person has exhibited an allergic sensitivity to all-porcelain restorations. Porcelain consists of metal oxides which are fused into glass. Since dental glass is formulated to be insoluble in water (or any fluid that can safely enter the mouth), the metallic molecules are not biologically available to interact with the patient's immune system.





On the other hand, it is possible to be allergic to nearly any metallic dental alloy. Even gold can prove to be an allergen occasionally, but since it does not dissolve in oral fluids under most circumstances allergy to gold is very rare (on the order of 1 in a million). Porcelain cannot be adhered to pure gold, and gold, by itself is too soft to be of practical use as a framework under porcelain. Thus, other alloys must be used under porcelain-fused-to-metal restorations. Gold is frequently used as a major component of these alloys in order to reduce the amount of base metal. High gold content metals used in the fabrication of Porcelain-fused-to-metal crowns are often called "porcelain-fused-to-gold" restorations.





The metal most likely to cause allergic sensitivity is nickel. This is especially true of women, since most women wear jewelry, and inexpensive jewelry is often made with nickel. This sensitizes the wearer to this metal. Labs generally offer four choices of alloy to the dentist: gold, high noble, noble and non precious. Noble metals contain a high percentage of palladium, which tends to be hypoallergenic (generally does not cause allergic reaction). Some non precious alloys contain nickel while all the other classifications do not. Very few dentists prescribe nickel containing alloys for use under metal to porcelain crowns. Very few labs even stock alloys that contain nickel for this purpose. As a consequence, we find that very few patients suffer from allergies to dental alloys.





Nickel is used in the formulation of stainless steel which is used to make prefabricated stainless steel crowns. Stainless steel crowns are used on decayed baby teeth. However, the stainless steel in these temporary crowns is quite hard and insoluble, and the nickel used in its formulation appears to be unavailable for allergic reactions.





An allergic reaction to dental alloys tends to develop over the course of several years and appears as a red (or magenta), inflamed line in the gums around the margins of the restoration. The allergic reaction stays localized in the gums. Upon rare occasion, the patient may experience a localized lichenoid reaction. Systemic effects are unknown (ie. a reaction to dental alloy does not make people sick or cause cancer, or any generalized illness).
