Can Tonsils Grow Back?
My daughter had her tonsils taken out last year. But she's started getting the same kinds of sore throats that she got before. Is it possible that her tonsils are growing back?
It is possible for tonsils to partially grow back. During a tonsillectomy, most of the tonsils are removed. However, some tissue often remains, so tonsils occasionally can regenerate (regrow) — although they probably won't grow back completely or to their original size.
If you're worried that your daughter's tonsils are growing back, talk to your doctor. But just because she still gets sore throats doesn't necessarily mean that her tonsils are growing back. Tonsillectomies may result in fewer throat infections, but kids can still get some. Sore throats also can be caused by other things, like colds, allergies, and dry air.
