    The worst dentist I have ever met!!
    TrueReview22 (1 review)

    This man talks a good game and does well to set you at ease, but any medical professional that makes a serious mistake and doesn't own up to it is seriously dangerous in my opinion. Dr. Leads perforated my sinus cavity from drilling too deep during a root canal, then injected the cavity with a chlorinated disinfectant that immediately put me in excruciating pain and made me feel like I was drowning. I pled with him from the chair to stop, but he didn't till after the syringe was empty. Finally I was able to sit up. I launched forward to find this fluid draining out of my eyes, ears, nose and mouth with a pain I can't begin to explain. Dr. Leads assured me that this was not uncommon and that the best thing to do is to go home and sleep it off. I did what he told me, but after several days and nights of pain, breathing complication, missed work and the horrendous stench of rotted flesh in my head (like a rotten onion in your head you can't escape) I finally sought a second opinion. I discovered Dr. Leads should have sent me to an emergency room immediately. I would have reduced the severity of chemical burns sustained to my sinus cavity that took months of recovery. I stopped seeing Dr. Leads, but 6 months later I discovered another mistake Dr. Leads committed. After a molar shattered, my records showed Dr. Leads treated a cavity in that exact tooth 8 mo. earlier, but Xrays proved he drilled & filled the wrong side causing it to worsen then shatter. NEVER AGAIN

    Dr. Leads is an excellent dentist, he is always concerned with saving the natural tooth. His goal is always to cause the least amount of discomfort even for those of us who are extremely nervous about going to the dentist in the first place. Very competent & friendly staff. I do not have any reservations in recommending him to others
