Some people say it is “tightly rooted teeth”, while others say it is called “all-rooted teeth”, which refers to two characteristics: the last tooth, which grows diagonally The last tooth grows diagonally against the front tooth. The crooked “tight root tooth” is an “honest” person who suffers. Since humans have evolved to eat cake instead of bark, the human chewing system has degenerated, so the length of the jawbone has become shorter. But the degeneration of teeth is slower than the bone. As a result, when the last tooth erupts, the space is taken up by the teeth that erupted in front of it, and it can only be squeezed into position, and it becomes a “tight root tooth”. The tooth that does not erupt in place will have soft tissue covering it. It seems that no medicine can solve this “evolutionary” problem. The gums that cover the tooth form blind pockets where food debris can easily leak and bacteria can naturally multiply. If you have the misfortune to bite through it, or when your body’s resistance is reduced, it will easily become “inflamed” and sometimes swollen. At this point, “anti-inflammatory drugs” is needed (but anti-inflammatory drugs are prescription drugs, must be prescribed by a doctor, even for yourself, you do not have the power). What is actually needed is to rinse out this blind pocket (this should be done by the dentist, you can’t see it yourself), and you can rinse more and more with an antiseptic mouthwash that also acts as a blind pocket cleaner. Once in a while the “tight root tooth” inflammation forget it, often inflammation, then it is better to let this “late” leave, leaving it here also does not play a role.
