Today my front tooth has chipped, probably due to the poor care I've given my teeth. I'm afraid it's most likely going to continue to get worse and not just that, but that my other teeth will eventually do the same thing as well. Also, my front 2 bottom teeth were knocked out years ago and the dentist put in these temporary fake teeth that fell out, they weren't very strong.

Is it possible to get single, permanent, fake teeth? Or are dentures the only option?

Have you considered Lumineers?
Look at this:

Hold on a minute, Trav. Yes, you can look into the above... and even permanent implants... but do the right thing first and get those teeth cleaned by a dentist - and have him give you some good instruction on keeping your natural teeth as long as you can.

Don't assume it's hopeless unless a dentist you trust tells you so.
