The process of teething is very difficult for young infants, and very painful. The tooth begins as a bud in the lower extremities of the jaw, and grows upward until it breaks through the jawbone. The flesh then begins to recede around it, as it continues to grow upward. When a tooth is removed, it does not affect the actual root of the tooth, unless the root has been heavily radiated during the removal process. As long as a person is alive, there always is a remnant of the root that continues to exist, even if the person has had a root canal done.
The Lord God Almighty expects that many individuals who have lost all or some of their teeth will again begin to grow new teeth. That process may not happen for another several years, but as individuals continue to cleanse and heal, teething will again begin. If you have had wisdom teeth removed, they too will be restored, and your jaw will be properly situated to accommodate them.
The Lord God Almighty El Shaddai
