Painless blisters in mouth

Question:

I seem to be getting blood blisters in the inside of my mouth and on/under my  tongue.  I get about one or two a week.  They are painless. What are these? I visited my dentist who claims there is nothing to worry about.

Answer:

This can be a number of things.  However, to get closer to an accurate diagnosis, we would need a lot more information from you, including such factors as your age, habits (i.e. smoker), size of the lesions, whether they leave a scar, if your lymph nodes are inflamed, etc.  There are soo many ailments that appear as red lesions in the mouth but here are a couple of suggestions that can possibly lead you down the right path.

Some of the most common red lesions that appear in the mouth are either recurrent herpes, also known as a cold sore.  Please see our article here for more information on cold sores.  Or, these lesions could result from trauma or rupture of a blood vessel (hemangioma), an allergic reaction, lichen planus, or could even be leukoplakia or erthyroplakia which both introduce serious threats.

In summary, it’s hard to reach a diagnosis with such limited information.  It would be best to visit your dentist and stress your concern about these lesions.  If he/she brushes it off, don’t be afraid to seek the opinion of another dentist or medical professional in the area.  In the end, it’s your health and you have every right to take it seriously.

Hope these tips help out and good luck,
