I have a couple teeth myself that wiggle slightly even though my teeth and gums are very healthy and I brush and clean my teeth daily.
I asked my dentist about the 2 loose teeth and the dentist said that the teeth are healthy and the gums are healthy and that the teeth that were wiggling a bit and only slightly wiggling and loose is normal.
The dentist said that teeth that are a bit loose and only wiggle slight is normal for some people but if the teeth are too loose then it could be caused by gum disease such as periodontal disease.
If your teeth are really loose then it's not normal but if the teeth are only a bit loose then it's normal.
Teeth naturally move slightly in some people and as long as you're not experiencing tooth decay, teeth pain etc then your teeth are likely just fine.
Teeth can also become loose due to tooth injuries and if that happens you should see a dentist as well.
But if the teeth are only wiggling slightly and you haven't injured your mouth or teeth then it's likely just fine.
