Does your jaw shrink overtime after wisdom tooth removal?

Not likely but teeth may get more space between. The dentist knows you jaw teeth better than we can ever know them in this venue

There is always bone resorption over time as one gets older and loses more teeth. At your age there is minimal shrinkage.

The overall shape of your jaw bone will no charge. The small area that supported the wisdom teeth will recontour. See your Oral Surgeon or your General Dentist for a full explanation. The small toot-bearing area that recontours will not affect the overall shape, size, or position of your jaw or the overlying soft-tissue facial drape.
