A piece of food or something may have gotten under the gum. Does she have her wisdom teeth in yet? If I remember correctly, mine came in in my late teens or a bit earlier. As they were pushing through, I always had swollen gums and infections. I used a water pik and antibiotics. Btw..the reason they weren't pulled is because they came in slowly but perfectly, tho the upper 2 broke decades later and were removed.

Just my opinion, Carole, but I would have used a different dental firm. I don't know if the docs talk to each other or compare notes, or want to contridict each other. All my 2nd opinions were with different firms.

I've only had 1 root canal and it was necessary. My dentist does it as a totally last resort. I wuv him.
