This was the first painless teeth cleaning I’ve ever had. The hygienist(Anna) used a numbing spray that only last about the time it took to clean my teeth and I had no sensitivity!!! I also got two cavities filled without any novocaine. I was super nervous but the doctor used her judgement to determine whether it was necessary or not and she advised me that they were small enough to go without any numbing. Never had a more pleasant experience at the dentist. Phewf.
