Thanks for your questions, I think that the most successful way of finding  the best dentist to carry out your smile makeover, would be to listen to recommendation from friends or relatives who have had similar work carried out. If this avenue is not fruitful, then I would suggest researching different cosmetic dentists on the internet, and maybe consider attending a few practices who offer free initial consultations. This would allow you to meet the dentist, discuss the options that they recommend and make an informed choice based on your experiences without any financial loss or commitment to treatment. I hope this is helpful, and encourage you to contact me again if you require further assistance.
Kindest Regards
