Hello, can teething in an 8 month old baby be the cause of the return of reflux?

Hello, my 8 1/2 month old daughter had reflux when she was born (always seemed to chew, cried when she was drinking, would regurgitate a little). We switched to nutramigen milk following the pediatrician's recommendations and the reflux gradually stopped. She now eats 3 meals a day and drinks the same milk. We have introduced all the allergens, but I give her very little dairy products because I find that she does not seem to tolerate them well. It's been a week since she has taken dairy products, but I have noticed for a few days that she is regurgitating again when she hasn't done that for months. She also cries when she has a burp during her feedings. I very rarely give her tomatoes and citrus fruits so as not to irritate her.
