Is a toothpaste allergy possible?

It is possible to be allergic to anything.  A toothpaste allergy is something that may not occur to you until your gums are sore and you can't figure out why.  

Besides gum soreness, toothpaste allergies can make the gum tissue red, swollen and cause sloughing (peeling) of the gum or cheek tissues.  

Though less common, I have even heard of toothpaste making teeth feel achy and sensitive.

Are you allergic to your toothpaste?

It can be difficult to pinpoint any allergy but paying attention to a few details will help...

Are you using a new product?  

Did you just buy a new tube of your usual toothpaste?  The ingredients may have changed.

Is your toothbrush new?  Sometimes a brand new toothbrush especially if it does not have soft bristles,  can irritate your gums.

Did you just start flossing?   Flossing can make the gums swollen and tender the first time or two. 

Did you eat something that may have irritated your mouth?  Certain foods can cause trauma to the gum tissue, tongue or roof of the mouth.  Foods with a rough texture, high acidity, or very hot foods will injure gum and cheek tissue.  

Are you using any other product such as dental floss, mouthwash, or chewing gum?  Any product that you may have just started using or may have over-used could be the cause.

Is your mouth dry?  If you have a cold or sinus congestion your mouth may be dry.  Dry mouth irritates the gum tissues. Click here for more about dry mouth.


One example of a toothpaste allergy...

This thread of comments started out with one question about Sensodyne Toothpaste and continues to draw quite a flood of responses from those who have had similar reactions. 

Ironically, this product was made to improve tooth sensitivity yet had the opposite effect for some.

I mention it only to point out that it is possible for anyone to have an adverse reaction to anything.  A bad reaction does not mean it is a bad product. 


How to know for sure...

If you have injured your mouth in some way, it should improve each day. 

Gum tissue that is irritated or traumatized should be allowed to heal.  Brush and floss these areas very gently or just leave them alone for a day or two until they feel better. 

For symptoms that don't improve, try changing products or use them less frequently to see if the problem improves.

Any irritation that doesn't resolve or at least improve after a week  is probably not the result of a toothpaste allergy and should be checked by your dentist or physician.
