I had to have two teeth removed both for pain from a deep cavity and they could not be saved. I have high anxiety with dental procedures, but Dr. Liang was very gentle and made me feel very relaxed. He took into consideration my nervousness with being numbed and he used a very small needle to numb the spot before he used the larger needle to complete the anesthesia. He followed up by calling me a couple of hours after the procedure to see how I was doing. That is the first time any doctor that I have experienced that. I would recommend him for anyone needing any dental surgury or procedure.
