Hello,
First of all you need to relax. As you are trying to treat it all by yourself, it is causing you some discomfort. As You already know about your condition , you should have gone for dental consult earlier. But it’s not to late, as you are still growing, you would be a good candidate for the treatment.
You need to consult an Orthodontist to find out whether your malocclusion is dental(tooth related) or skeletal(jaw related). Treatment is done accordingly.
Next Steps
Please consult with an orthodontist for your malocclusion.
Health Tips
