Brentwood branch. I had originally written a review with 5 stars for finest dental. I still believe it can be amazing IF your treatment is smooth with no problems. I've read some reviews here previously that makes me believe it is not just me that has come across this issue. Once something hasn't quite worked out for them, there is an incredible lack of responsibility from the team. I finished my invisalign treatment here and had fixed retainers fixed on the back of my top and bottom teeth. All was great up to this point. However, within a week and a half, BOTH fixed retainers came unglued from my teeth. I have had braces in the past, and worn fixed retainers for over 10 years, without even the slightest of problems. Nothing ever came unglued. However, upon mentioning this to the staff, I was told that I had been told that the retainers wouldn't be permanent and that they were likely to need replacing at some point. BUT IN LESS THAN TWO WEEKS? I can't help but think that now that I have finalized all my payments to FinestDental, the level of service received is just abysmal. Unfortunately I have had to move countries straight after the treatment, and have had to pay more money for someone else to fix the retainers to my teeth properly. I contacted Finest Dental to try and come to some sort of arrangement, seeing as I am unable to spend thousands of pounds to return to the UK to re-fix these retainers, but their answer was simply that I should wear my aligners permanently until I am able to return. So all in all, after all of my 5 stars and congratulating them on the service they were providing, I am now more weary about recommending Finest Dental, and would urge you to think carefully before choosing them. They are great once you are a paying customer and nothing has gone wrong, but take little responsibility when something does and make no attempts to right their wrongs.
