I was wondering is it possible to have all your wisdom teeth if you only have 30 teeth?

Wisdom teeth: Yes, if you mean erupted teeth in your mouth, and you have never had any removed. Some people have teeth that have never erupted (impacted teeth), usually wisdom teeth. But they can also be other teeth that have been crowded out of the arch. Although rare, some people never develop teeth, usually wisdom teeth.

Yes: We normally have 32 permanent teeth in the mouth. A person who has lost six teeth due to various reasons could have four wisdom teeth erupt into the mouth or remain impacted or unerutped.

Yes: The teeth you can feel and are erupted, if all do so, equals 32 in normal situations. If only 30 teeth are visible or functional, the other two may be impacted. Some people never develop wisdom teeth or not all four, so it is conceivable to have only 28 permanent teeth.

Yes: Yes. the normal complement of teeth is 32. If you have 30, have not had extractions, then 2 of your teeth are impacted, have been extracted or congenitally absent.
