Chin implant too big, causing numb tooth (Photo)

... your chin implant was not indicated, it is not a matter if the implant's size was right or not, no implant should have ever been used on you, neither and augmentation genioplasty; you needed NO augmentation at all, using chin implant or other method of augmentation was an unwise, disastrous and awful aesthetic decision (not your fault, of course).
Your chin was too heavy and masculine, actually oversized, and to feminize its boxy shaped needed a multidimensional reduction genioplasty to narrow its widht and round its shape (this means feminizing it), and evidently you needed, due to your long face, vertical reduction on its length.
You got a chin implant which is not the right indication and furthermore is producing complications, sad to see your situation. It is time you seek better and more experienced opinions about your genioplasty.

It is true the vast majority of surgeons use the implants instead of the osseous surgery to adjust the chin, but this is a matter just of lack of experience and comfort ease; implants play no role when there is an autologous alternative which, actually, has plenty of superior advantages.
Being an option, chin implants have serious disadvantages, especially in the mid and long term, patients are rarely happy with them after 5-6 years, all are out sooner or later. A quick research just on this website sheds light on the common, frequent and serious complications and side effects chin implants entail, like dislocation, malpositioning, infection, over or under corrections, visibility, fake looks, nerve damage, chronic pain, poor aesthetic results and in general patients' dissatisfaction; not to forget chin implants are not versatile, they are unable to provide vertical increase, horizontal axis modifications and in most cases sufficient anterior projection; as obvious as it sounds but we have to bear in mind chin implants play absolutely no role when the chin needs reduction of one of the spatial axes; actually it is very common receiving patients who seek chin implant removal and replacement by an osseous genioplasty in the same procedure.
Fillers, another tempting resource, are a very dangerous option in chin reshaping, potentially destructive, unable to reshape and enhance respecting the basic principles of anatomical beauty, leading to mid and long term serious complications (granulomas, deformities, fistulae, etc) and the worst is they can't be removed in most cases.
Burring the chin is, strictly said, osseous chin surgery but should neither be performed, ever, since just flattens the chin by destroying the natural dome of the jaw, deletes the labiomental crease and due to the detachment of the mentalis tendon this technique commonly leads to a droopy double chin, a serious aesthetic complication.
A multidimensional sliding genioplasty allows to a versatile surgeon full customization for augmenting, reducing and leveling the chin in any of its spatial axes, leading to a myriad of combinations to suit every individual's chin anatomy and facial balance requirements; you can masculinize, feminize, round or make square, increase, decrease, supply bone graft, remove bone portions, slide fragments, etc. This absolutely impossible with other method than multidimensional sliding geniplasty, a technique providing a series of advantages among which worth mentioning:-lifetime procedure, no more revision or renewal procedures, unlike implants-more natural than implants, the procedure is totally undetectable -no visibility of implant edges during gestures, expression is even improved, nicer smile-improves the double chin effect at the sub-mental muscles (floor of mouth) hammock caused by lack of tension there; also improves the shape and tension of perioral muscles and tightens up the jowls, creating a beneficial side effect in form of an indirect facelift and neck lift, all patients see their face indirectly rejuvenated; implants do not offer this feature-no future displacements or neuritis of mental nerves-no droopy double chin (the mentalis tendon is not detached) -way lower rate of postoperative complications if compared with implants, like infections, displacements, neuritis, etc-no need for complex plates and screws or teeth braces that may need future removal; just steel wires synthesis may suffice, they stay buried into bone callus producing no disturbance
The cons for the patient are essentially the costs associated with osseous genioplasties, however it sounds cheap if you consider the lifetime benefits; obviously the main disadvantage happens on surgeon's side, since it is more technically demanding than chin implants, few surgeons are experienced or comfortable with multidimensional osseous genioplasties (though I personally perform 100% of the chin procedures by this osseous method); patients have difficulty in finding surgeons experienced and comfortable in osseous genioplasties able to freely modify the chin shape and size based on their aesthetic and gender goals.
You'll find in this website hundreds of negative experiences with chin implants in the short and mid term, do read my profile's Q&A and you'll find them too. I am doing osseous genioplasties for more than 15 years with the highest success and no one patient sought afterwards switching to chin implants, totally the opposite, I did many chin implant removals and one-staged osseous genioplasties to replace the implant and enhance the result.
See the link below to find few cases of my own practice very similar to yours which I had the opportunity to operate successfully on, sharing a lot of common features with the technical problem you have posted.
If you wish better grounded opinion well lit, focused and standard images have to be assessed: frontal, both lateral and both oblique views, also from underneath.
Feel free to request any additional information from me.

I recommend following up with your surgeon. If you're unhappy with your implant, you have 2 options:
1)  Get a different-sized implant 
2)  Remove the implant altogether
It is rather easy and quick procedure to place a different implant if the implant is made of silicone.
I hope this helps

The implant does look a bit large for you with excess projection.  A change to a smaller implant would be more pleasing for your chin.  As far as the tooth, the nerves in the area of the implant do not affect tooth sensation.  Nerves in the area affect the lip and sometimes lip numbness can result.  The incision should improve with time.  

 Hi, I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over 30 years.  You should discuss these symptoms with your chin implant surgeon as they may indicate impingement of the implant on one or both mental nerves.  Sadly, a medpore implant becomes incorporated into the bone as quickly as 1 month making removal very difficult requiring extensive surgery (unlike removal of a silastic implant which is very quick and easy).  At 7 weeks there may still be some swelling so without knowing what you looked like before the chin implant (how weak the chin was pre-op) and the size of the implant, it's difficult to comment on whether your chin "is" for "will be" over-projected from the medpore implant. I prefer using silastic extended anatomical chin implants that in my opinion and experience create the most natural looking chin augmentation.  Silastic implants are very well tolerated and can be easily removed.  As described below, when properly placed, there is no need to secure silastic implants with screws or sutures...which means there's really no need for a medpore implant that integrates into the bone making replacement or removal extremely challenging.   When the chin is weak, this creates an imbalance making the nose appear larger, the mid face top heavy, the lower face looks short, de-emphasizes the lips and allows early formation of a "double chin".  
 Proper placement of a silastic chin implant adds forward projection to the chin thereby creating harmony and balance to the lower face.  Using the same incision, liposuction can be performed to reduce the fat and further shape the neck.  Excess skin, from below the chin, can also be removed through the same incision.  
 I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty (requires extensive tissue dissection, bone cuts and placement of metal screws and plates to secure the cut segments of bone).  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  
 In my opinion and experience there is no need to secure a silastic chin implants with sutures and screws when the following conditions are met:
 * Select a silastic chin implant ( I prefer the EAC) that doesn't have too much projection (thickness) as this becomes a problem stabilizing the implant under the periosteum when the implant is too thick.
 * Place the implant through a small curved incision under the chin which allows direct access to the periosteum (under the mentalis muscle) while preserving the muscle attachments.  This prevents upward migration of the implant which can occur when the intra-oral approach is used that severs the muscle attachments.
 * While the center or body of the chin implant should be placed at a perpendicular angle the chin bone in order to provide the proper forward projection to the chin, the "wings" of the implant should be at a lower level and follow the inferior (bottom) edge of the jaw line on either side of the chin.  When properly dissected and placed, this will be below the mental nerve foramen and be just wide enough of a dissection to accommodate the tapering wing.  There isn't enough room in this technique to allow the wings to migrate upward and contact the mental nerve.  In contrast if the dissection, along the sides of the chin (jaw line) are performed too high...this will place the mental nerve in danger and if the side dissection is too wide, the wings will have a space within which to migrate upward.
 * We have all of our chin implant patients avoid touching and feeling their chin implant for 1 month post op.  We also ask that they sleep on a U-shaped airline pillow for the same time.
  Our experience when following the technique described above is that the silastic chin implant does not need to be secured with sutures or screws and does not move.  I have placed silastic chin implants in military, SWAT, LE, professional fighters, as well as actors and many regular people who are active.  In addition, I have had the opportunity on numerous occasions to replace silastic chin implants (placed by others) that had been screwed into the bone.  During the replacement it was evident that the metal screws pushed right through the soft silastic implant as it was tightened down on the hard chin bone.  Which makes perfect sense.  So in the long run, these fixation methods alone are no guarantee that the implant won't move.  Proper placement, proper implant pocket creation and meticulous closure of all the tissues layers is what is required in my humble opinion.Hope this helps.
