Omg! The doctor and staff were incredible! I was terrified of the procedure of removing a molar, since I've been through that before. Besides making me feel comfortable, they explained everything and were gentle. The procedure of numbing me was the most PAINLESS I've ever had and the extraction was over in just a couple minutes! I was as happy and pleased as one could be after that work! Definitely recommend and will be using them again! Thanks doctor!
