Dr. Mantena is very nice and knowledgeable. He works great with adults and children of all ages. I have had a couple of root canals, fillings and caps and he has done a terrific job each time. The office is great about getting you seen in emergency situations. I broke a tooth and they were able to see me the same day. The cost is not bad. The staff is always pleasant and will to assist you with any dental insurance questions or problems.
