My sister had tooth pulled Saturday, at emergency dental clinic.

Her extracted space is hurting and white around the gums. She said it had been hurting/sore before she had it pulled.

She was eating hard candy and her crown broke and they had to pull it. It's been giving her problems for years.

Started taking antibiotics Monday night Doxy-cycle HYCL.

Would appreciate any advice...

We don't know why her gums are white.
