Everytime I brush my teeth I start having sneezing fits and a runny nose for about 20 minutes. I’ve had allergy tests in the past and it only says I’m allergic to Australian grasses/pollens. This has only developed in the last 2 months or so. I have no idea what’s causing it and how to stop it.

What Causes Sneezing When I Brush My Teeth?
Hi.. Thanks for the query.. The symptoms of sneezing and running nose during and after brushing seems to be due to Allergic reaction to the toothpaste that you are using.. The common ingredient in toothpaste that can cause allergic reaction is sodium lauryl sulphate.. It can cause allergic rhinitis due to reaction to the ingredients of the toothpaste.. So my suggestion is to get a hypoallergenic toothpaste from a pharmacy and see if the symptoms improve.. For now if the symptoms are serious or persistent you can take antihistamines like Levocetrizine or Benadryl and do steam inhalations.. Hope this helps.. Regards..
