Do gums heal after scaling?

As the gums heal they might change their shape around the teeth. This is normal as they tighten up and shrink during healing. If extensive root planning was performed, chewing hard foods such as meet or raw vegetables may be uncomfortable; this should last no longer than a few days.

What are the side effects of scaling?

If scaling is not done properly, then it can loosen the teeth. There is a chance that a person may lose multiple teeth if scaling is not done the right way. The risk is even higher among patients who have heart problems and diabetes. Gum disease can also result if scaling is not done properly.
