Try to maintain your hygiene as best as you can. Did you have a hard time brushing and flossing during your strep throat episode? I'm thinking maybe you didn't brush and floss well during that time and maybe you're experiencing some symptoms from gingivitis.
The Strep is gone now just some ulcers left on the back of my throat. Still taking the Amoxicillin as per my doctors orders. My gums are still tender. I used to be able to brush em then floss with no pain but now when I brush It hurts and flossing is out of the question.
How are you feeling now? Have the gums improved? Usually the mouth in particular isn't associated with strep throat.
