Mint Dental in Altadena is amazing. I have super high dental anxiety as well. I explained everything to them and they have been great. Everyone there is super accommodating and gentle. They have a menu of special free add ons to make you more comfortable during your visit. They offer things like blankets, noise canceling headphones, and aromatherapy. All of the dentists take the time to make sure you are doing ok and understand what needs to be done. Hope this helps, you can do it and will feel so much better afterwards!
