Do these look too short? I have my temp crowns in right now and tried my permanents on to see how they would look and took a few pics and pasted here. I'm 25 and these feel slightly small to me and I'd prefer them to be a little longer. My dentist said if we made them longer, it would negatively affect my bite and cause friction so I would want to go by his word. I am also aware of the crown lengthening of the gums but unsure if I should go that route. Anyway any feedback is appreciated, thanks!
