Chin implant after mewing - is there a risk of the implant coming out or infection?

Mewing Is a technique that involves pressing your tongue against the roof of your mouth, for the sake of improving jawline appearance and facial structure. I do not believe this would be at all effective for malocclusion of your teeth. In fact, I do not believe this technique would lead to benefit at all. In that regard, it certainly cannot hurt, and I do not believe that it would lead to infection of your chin implant that was placed uneventfully 1.5 years ago. Thank you for this question! Sincerely, Dr Joseph

Thank you for posting your question here!Chin implants were made to give your chin more projection or width/height, they do not affect teeth alignment. If you have a bite issue that could not be fixed by orthodontics then orthognathic surgery might be an option for you. That being said when it comes to mewing there are limited studies on the subject but for now the consensus is that it has no permanent results and it only gives you temporary improvement in your aesthetics while doing it.
I hope this helps, best of luck!
