Can a lower lip be raised or tightened to hide the lower row of teeth?

The way we do this is to go inside the mouth and attempt to lift up the chin tissue which is pulling down the lip.  You'd need to wear a wrap around your face for a week or more but it can be done though it is challenging especially if you want a lot of lift.

Sometimes with an upper lip lift, as the upper teeth become more visible, the lower teeth are less noticeable. That being said, I do not think that you are a good candidate for an upper lip lift. I would consult with an oral surgeon to check the alignment of your jaw and to see if you qualify for orthognathic surgery. 

Many thanks for posting your question and photosMy observation from the photos is that your bottom teeth project forwards more than your top teeth, resulting in the concern you describeI would therefore consult with a maxillofacial surgeon to discuss procedures to set back your lower jaw (or advance your upper jaw) which will address the underlying issueGood luck in taking this forwards

Gregarious702860,You can mess around with lip lift surgeries but you more likely need orthognathic surgery. A craniofacial specialized plastic surgeon or maxillofacial surgeon should be able to determine the cause of your tooth show and develop a treatment plan.Good luck,Nirmal R. Nathan, M.D.

Although it is not a routine procedure, there is a way that lower lip may be brought up, in a more functional and aesthetic position. Consultation with board certified plastic surgeon with good reputation in both reconstructive and cosmetic surgery is recommended. Good luck.
