Ive been a thumb sucker since birth and am now 25 and have a overbite and struggle to naturally close my mouth just feels uncomfortable. my face has changed slightly luckely my appearance isnt bad as some i have seen i was wondering if an avisalign would do me any good to help my jaw relax so i dint have to hold my mouth shut and be always aware not to relax my jaw as its not a good look. im not sure if fixed braces would be better for me or not? i have a phobia of dentist so less invasive is best but im willing to what needs to be done your advice would be very usefull and how much would these procedures cost?
