No, you may just need to flush earlier (before adding any toilet paper, courtesy

However, it could also be a poorly designed toilet that simply doesn't have a
large or proper drain design, "bad toilets" are quite common. A final cause
could be that the pipe which the toilet attaches to has rusted itself mostly
shut and needs to be literally chiseled back to its full diameter.
