As you sit in your dentists office waiting for a cleaning or exam, you probably have a list of things youd like to discuss – X-rays, whitening, cavities, bad habits. But heres one that probably doesnt make your short list: allergies. Though common allergies like hayfever wont affect your visit, certain contact allergies may cause problems. Allergic reactions to latex, anesthesia1 and, in rare cases, certain metals – which may be used in fillings, crowns or partial dentures are all important to mention.2, 3 If you do have an allergy to anesthesia, latex gloves or something else thats commonly used in dental practices, dont worry. There are safe alternatives for everything, and your dentist will be able to discuss options with you for instance, neoprene or nitrile gloves instead of traditional latex.4 Even if you dont think your particular allergy is something that is cause for concern, its worth a quick discussion with your dentist. You should always mention any general health issues during your dental visit.
