It is not necessary to remove teeth in adults in order to gain the necessary spacing needed. Each tooth can have 1/2 mm on either side trimmed away as the enamel of the teeth are thick enough to do so and even more in back teeth. It is non intrusive and you get 7-8 mms of space in a 1/2 hr session, which is about equal in width the the crowded lower incisor, which then can easily be moved in to the correct alignment within 3-6 months with with today's thermal activated NiTi wires.

Additionally, tinnitus might be a complication of misaligned teeth, but more importantly, the misalignment of of your upper and lower jaws that occured with the removal of teeth and not treating for stability in your bite by aligning your upper and lower jaws and then aligning yor teeth to that position. Your appropriate treatment would be treatment of your temporal mandibular joint (TMJ) with a removable bite splint, then slenderizing the sides of your lower teeth and widening your upper arch with a retainer type appliance, and finally brackets to straighten the teeth. Usually would be a 1 year effort, perhaps a little longer. The deal is that TMJ treatment is usually covered by medical and/or dental insurances.

As a dentist, I can tell you that unfortunately your dental condition is not static, and will continue to change as the years pass. The crowded spacing on your lower anterior teeth are not aligned "shoulder to shoulder" and will continue to become more crowded as your posterior teeth continue to incline lingually(toward your tongue side) and the wear to your upper incisors on your left side(taking into account it is a mirror shot) on the edges and back sides of those teeth. Women more likely will develope jaw joint problems from such alignment, but men tough it out better.
