Hello doctor, please help me out...i'm 19 years old and my right canine tooth is loose, it makes me really uncomfortable. i don't know what to do. please give me some advice on what to do.

Go see your dentist: When it comes to your teeth, best advice is to brush & floss regularly (or at least those you want to keep!). And when it comes to something wrong w/your teeth, best advice is to go see your dentist.

Please see a dentist: It is hard to imagine why your canine should be loose at your age. This needs to be physically examined to determine why. Please see a local dentist for an examination.
