hello and welcome to HCM forum,
yes there is a way out to get the space filled which is present in the lower front teeth,
your
dentist knows better that whether the scaling needs to be done first or the extraction of your wisdom tooth,
Ideally you should get your teeth cleaned every 6 months, as well take measures to maintain your
oral hygiene.
there are number of options as to how a dentist can fill up the gaps between your teeth, and to decide which option will be best for you, we need to check your teeth clinically.
as i cannot do that, therefore i can only tell you what all options are available,
1. composites,
2. bridge(FPD),
3.laminates/veneers,
4.orthodontic treatment.
you can ask your dentist about all of this and then he/she will let you know, which one will be the best for you,
i wish you good health.
