You look just like you said, your teeth are a little protruding and your mandibular teeth are a little crowded. This situation can be improved by orthodontics. In this case, I suggest you go to the orthodontics department first and let the doctor examine your teeth in detail. Take your tooth model, take photos, calculate and data, design a correction plan, and see if your teeth are crowded or not, and whether it is necessary to extract teeth for correction. Then, according to the photos you took, your gums are inflamed, so you need to go to the oral periodontal department first, that is, let the doctor see if there are stones on your teeth, if there are, wash your teeth, and then the periodontal tissue will return to normal, then consider it and correct it. Pay attention to maintaining good oral hygiene in the later period.
