I notice my teeth look like a slight overjet. Should I get treatment or is it not needed? (photo)

Based on your photos, your smile is very nice.  Furthermore, your top front teeth are always supposed to slightly over lap your front bottom teeth; this is natural.  Now, of course you could do things to make it "perfect," like use orthodontics to decrease your overjet some and also whiten your bottom teeth some, but it is totally up to you.  If you were my patient and you were telling me that people always complement you on your teeth, I would definitely suggest whitening them some and then using Invisalign to slightly retract your overbite.  Good luck and I hope this helps.

hi, from the photo it seems that you have perfect set of teeth. but it depends on individual perception. i would suggest take some good professional fullface photos from different angles and then evaluate with someone you trust. if you still feel, it could be improved, seek our help. 

Overlapping is normal, we usually have 2-3 mm horizontal and 2-3 mm vertical.  From what I can tell, yours is perfect.  Whitening is likely the only thing left to be "Perfect"
