I don't have a website to offer but I will say this...
In a tooth ID exam they're going to have to present you with a tooth that has SOME distinguishing characteristic to it. If you get a multi-rooted premolar with a mesial concavity, think maxillary 1st. If you get a 5 cusp molar, think mandibular 1st.
You should know how to distinguish one tooth type from another (molar vs PM vs anterior).
You should try to list 2 or 3 unique characteristics of each specific type (mandibular incisor vs max incisor vs mand canine vs etc). For instance the maxillary premolars tend to be a bit longer B-L and the mandibular PM a bit more square shaped.
Then list the characteristics that separate teeth from there into specific teeth. The mand 2nd PM often times has the Y shaped groove with 2 lingual cusps. The mand 1st PM has an occlusal surface that is at a 45 degree slope and also a ML groove.
Remember... again... your instructor will make sure there is a way for you to ID it as a specific tooth. It might not always jump out at you but if you can narrow it down to 2 teeth you'll have an easier time.

Thanks for the pointers! I'm starting to feel pretty comfy with it, just need lots of practice now. Found a few websites, so between that and your pointers I should be fine.

Okay, everything Street said is great, but don't underestimate the canines. I did about 15 jars of teeth for practice until I thought I had them down stat (missing none or one per jar). But I get to the exam...and they put mutliples of teeth on there, like 3 number 3's (that was easy..), and all sorts of other multiples, so it messes with your mind. Just be sure you can know numbers 11 from 27 and 6 from 22. A maxillary or mandibular attritioned down can look VERY similiar to its counterpart in the diagnonal quadrant.
- What were some good websites that you found?
Here's the few that I have been using...I hope they help!
