Your concern is completely reasonable — removing four permanent teeth sounds frightening, and you should understand why before agreeing to it. The important point is: extractions do not automatically mean you will be left with four visible gaps. In orthodontic treatment, teeth may be removed specifically to create space, and the braces then use that space to move the remaining teeth into their planned positions. The intended result is normally closed spaces with a corrected bite, not four permanent gaps. For a significant overbite, extractions can sometimes be the most appropriate way to create enough room to move prominent upper teeth backward and correct the bite. But whether you specifically need four extractions cannot be determined simply from the fact that you have an overbite. Orthodontic planning depends on your facial profile, amount of crowding, tooth positions, bite, jaw relationship and X-rays. So I wouldn’t tell you either “definitely extract” or “definitely don’t extract” without seeing your orthodontic records.

Removing 4 tooth can be scary but the it is very common when orthodontist want to create space for the teeth after they move backward. It would be better if you can attach your reports. Usually the teeth that are removed are not that visible so you need to fear about it looking worse at present. The ultimate goal of all dentist is to give you a bite with harmony.
