My daughter just got her braces off and received an acrylic retainer.  Since she started wearing the retainer, she has had mouth pain, severe itching and red bumps all over her tongue.  She has severe eczema and has extremely sensitive skin.  Could this be some kind of allergic reaction to the retainer?
Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have small daughter having retainer yes problem of mouth pain, red bumps can be due to retainer if it has sharp edges or air bubbles causing irritation.  Don't worry on tongue and painful gums you can apply anesthesia ointment McCoppin or Colonel twice daily for 5 days Consult dentist and go for trimming of retainer if any problem is there Do warm saline gargle two - three times a day. Hope this will help you. Wishing her good health.
