Just got back from the dentist getting 2 old fillings replaced. Not my favorite way to spend time but I have been so impressed with Dr. Richard Berg over the last few years. I have had multiple fillings replaced and crowns installed and have never once felt the drill. This time he had me in a full belly laugh while filing my tooth :) This is seriously a no pain dentist. Dr. Green, a local gum doctor told me he thinks Berg is the best dentist in Lanc. Co. I know that there are many good dentists and I have had several which I felt did a great job as well. But this guy is outstanding. If you are looking for a new dentist, I totally recommend him
