4. Loose tooth
Of course, a wiggly tooth is perfectly natural when you’re six years old. But when you’re 46, you need to see a dentist about it. “The number-one cause of loose teeth is gum disease,” says Hayre. And since gum or periodontal disease can cause tooth loss, it’s important to get your oral health back on track.
Occasionally, a loose tooth can be a sign of oral cancer. An accidental impact to your mouth can also loosen a tooth or two. Either way, you shouldn’t ignore a tooth that’s less than solid, because that’s not normal for adults.
