In our previous blog, latex allergies were discussed. This post will continue that conversation and go over a couple of other dental allergies. 

Contact Dermatitis? What is that?

When our skin comes into exposure with chemicals in soaps, perfumes, or cosmetics and has an allergic reaction, it is referred to as contact dermatitis. Side effects of this reaction consist of rough, itchy, and burning skin. 

There are two categories of contact dermatitis:

• Allergic contact dermatitis is a skin allergy to nickel, poison ivy, latex gloves, cosmetics, or fashion jewelry.
• Irritant contact dermatitis occurs when our skin has been irritated by a material over some time. 

Some patients may experience allergic reactions to materials such as amalgam fillings, toothpaste, and fluoride techniques, along with chemicals that are utilized in dental bonding and porcelain. The areas where the reaction occurs are the gums, lips, tongue, and skin.

Local Anesthetic Allergies?

Many patients wouldn’t be able to sit through a tooth extraction or a tooth filling without the use of local anesthetic. Did you know that some patients are allergic to local anesthetics?

Sometimes, when we use anesthetic, some of it gets into the bloodstream and can cause the heart to race, a lot like having too much caffeine. It’s normal and usually stops in 5-10 minutes.

Some warnings which may indicate that a local anesthetic allergic reaction is happening, however, are these: After the local anesthetic is administered, patients may experience swelling of the mouth. In more extreme cases, patients may experience trouble breathing. Other side effects of this reaction include feelings of panic, heightened heart rate, hyperventilation, and contact dermatitis.

Why might some patients react negatively to local anesthetic? This may be caused by sensitivity to epinephrine and preservatives, including methylparaben. Those who believe that they may be allergic to novocaine or other local anesthetics can take a skin allergy test to find out if this is the case.

It’s vital to remember to share your medical history with your dentist. This may determine if local anesthetics are the appropriate solution for you.
