Hi, From what i can see it does seem like you have overjet. That is when your top teeth protrude more than they should and you will benefit from braces. Clear aligners seems like it would be a good option but of course consult with a dentist to evaluate and confirm. I am only judging by one picture. Also the clicking may be due to a grinding problem since you say it does that when you bite and move your teeth. You may be grinding at night, have your dentist evaluate you for wearing down of your teeth and in that case you may need a night guard. If you decide to go with clear aligners, then you won't even need to get a night guard as wearing those all day/night will help with that problem as well.
Hi, thanks for your question. You will definitely benefit from braces and your two front teeth will no longer look like they are protruding or too large. They look that way because your two side teeth are pushed back and once the braces brings them forward, you will have an even smile. You also have a crossbite on the right and some spacing on the left that will be corrected. I would suggest clear braces, as i have done many cases as such that work really well.
Yes, your bonded fillings can be adjusted in between the teeth. The Dentist always tries to keep a tight contact in between teeth so food does not get caught, however if its too tight and your unable to get floss through, then you do need an adjustment. Just mention that to your dentist and they will be able to put a sandpaper like small strip in between to smooth it so you can get floss through.
