Uneven gum line or orthodontic issue?

Orthodontics are one way to change the gingival heights and make them even.  The other way is to talk to a periodontist about crown lengthening  If you have already had resorption, the amount of gum and/or bone that could be removed needs to be determined.  Another procedure you can ask about is a lip repositioning procedure to drop your lip down.  This is done if too much gum is showing and the height of the gum tissue is recountoured.

This looks like a combination of both an orthodontic issue AND periodontal (gum) issue called ALTERED PASSIVE ERUPTION (you can Google this). Basically, your teeth are a bit uneven AND your teeth never fully erupted. Chances are you will need Ortho treatment as well as some minor gum recontouring at completion.

At first glance you seem to have a canted smile.  What that means is thatone side of your mouth (right) is a bit lower than the left.  This could besomething relating to your skeletal development during growth or possiblyhow your orthodontist finished your treatment.  There are sometimes limitationsto what we want as ideal and what is actually obtainable.  In the short versionyour gum follows your teeth.  Your gum is lower on your right.  It is possible toraise it but i would be cautious as to how much I would go.  You may be borderingon exposing your root and that could cause long term sensitivity.  This is somethingyou may want to discuss with your dentist or periodontist. If you are extremelyself conscious about your smile than you may want to seek an opinion froma cosmetic dentist as well.
