Loose teeth are fun for kids... not so much for adults.
It is worrisome to feel your teeth move.
Depending on the cause, tooth mobility can sometimes be improved easily. This question from Dana, is one that comes up often.
Hi Dana, That is a good question. There are a few things that can make your teeth loose.
Teeth move and shift and may be loose one day and not the next.
It's good that your dentist has checked your teeth and there are no obvious problems.
If the problem continues, ask your dentist again at your next check up.
Details like the time of day you notice your teeth feeling loose or the type of food you are eating when it occurs, help the dentist know if there is a problem.
In the meantime
Pay attention to the position of your upper and lower jaws. If you find yourself clenching your teeth, it could be making your teeth slightly loose.
Loose teeth from clenching or grinding is harder for a dentist to identify because your teeth may not be loose all the time.
One possible solution
Once you know if you are clenching or grinding your teeth, you may want to invest in a dental appliance called a night guard or teeth grinding guard. These appliances can be custom made or purchased OTC. More about custom vs OTC guards here.
If you find yourself clenching your teeth during the day, it is very likely that you also clench them at night.
Since your dentist didn't see any problems, it is not likely that gum disease is making your teeth loose.
But gum disease is probably the most common cause of loose teeth especially if they are loose all the time, here is an article that explains these symptoms.
