allergies to dental materials

How do allergies to dental materials (cementing materials, crowns, etc) manifest?

Re: allergies to dental materials

The vast majority of dental materials do not produce an allergic reaction. A few will. The most common allergic reaction to dental materials used in the mouth will be an allergic reaction to nickel in non-precious crowns. Approximately 10% of women and less in men have a nickel allergy. You can tell for sure if you have a nickel allergy by taping a pisce of nickel to your arm for a day. If you have red tissue underneath, then you have a nickel allergy. During the 1970s when gold prices soared, non-precious metals were developed and used as the base metal for porcelain fused to metal crowns. There are still a large number of dentists who use non-precious metals in their crowns. When used in an allergic patient, the gum tissue around the crown becomes red and irritated. Crowns that are all porcelain or used with semi- or precious metal do not have nickel.

Latex allergies are probably the second most common allergy. A true allergy can cause difficulty breathing and rashes. If you have a true latex allergy, then have your dentist use vynil gloves and request use of septocaine as an anesthetic (it is currently the only one that does not use latex in the plunger).

Acrylic allergies are also seen. Acrylics are used in dentures. Usually it is not a cured acrylic that is the problem as much as it is the liquid (monomer) used. It also maifests itself as a contact dermatitis (reddness and itching tissues).

Many people say they have an allergy to epinepherine (contained in the local anesthetic). Since humans produce their own epinephrine, an allergy to it is not really possible. Usually what happens is that some of the anesthetic is injected directly into the blood stream instead of the tissues. This does happen sometimes and is sometomes unavoidable. As the epinephrine enters the blood stream, the patient's heart rate increases dramatically and the patient feels like they are having a heart attack. They may even faint. Unless the patient has some underlying heart condition, this occurance is self limiting and rareloy poses any real danger. These effects will last 3-5 minutes.

Any other allergies or manifestations to dental materials are extremely rare.

Re: allergies to dental materials

Thank you for your response. I have had some problems for a year now after dental work, and Im just exploring all possibilities. What happened is that after a crown prep the area around and behind my tooth has just felt odd. First it felt' heavy' for several months...then it was better..then it came back....and now it is more of a 'burning sensation' but there is no visible reaction on the gums or anything. Its just weird, and my best guess is some nerve damage. (Im pretty sure there is no nickel in the crowns.)

When I was having a white composite filling put it my mouth got all itchy during the poceedure. It was during the part when they put that "glue" liquid in the drilled hole right before they put the composit in.
After the composit was in I didn't have any itching.

Re: allergies to dental materials

Depending upon thge generation of bonding material used, the tooth is etched with a phosphoric acis gel prior to placing the bonding material and composite. If the etch made it to your soft tissue, you will get this itchy/tingling sensation. After it is washed off or diluted by slive, it will be all gone. THis is not an allergic reaction, just a reaction to an irritant.

Re: allergies to dental materials

So would your best guess to my symptoms be some damage to the nerve rather than an allergic reaction of some sort? The crowns are what they call 'high noble' (I think that is correct) anyway they are gold and whatever they put with that.

Re: allergies to dental materials

Gold, platinum and palladium are the major components. It would be good for your dentist to examine the tooth to see if there is an abscess developing.
