Though my expression in this picture may not show it, the surgery was a complete success😂. This was such A big one, it may be the last one I need. Hopefully at least. Those who suffer from Cleidocranial Dysplasia usually have Supernumerary teeth, which are extra teeth that grow in the gums. I’ve had several surgeries to extract these teeth from within my gums and help expose the teeth that should have already grown in considering my age. In this surgery, the team of amazing medical professionals extracted 14 supernumerary teeth and exposed six of my adult teeth. I was under for four hours. My recovery for the past few days has been great and I can’t thank the team that did the surgery enough. Thank you all for your kind wishes and prayers. It means a lot.
