Could my oral b electric toothbrush be causing gum recession?

It is possible: An electric toothbrush can traumatize your gums if you use too much force.. Use a feather touch with an electric toothbrush and change the head every 3 to 4 months.

Unlikely: yes, if you use excessive force in brushing, it can, but used properly it will make your gums healthier

3 causes: 3 most common causes of gum recession are 1) gum disease, 2) malocclusion, & 3) overly aggressive brushing technique. Don't blame the toothbrush, blame the operator. Talk to your Dentist/Hygienist about your oral health and your oral hygiene program.

It is possible: If the wrong tooth brushing technique is used or being overly aggressive can wear down the gums.
