Spacing is not because of molar relations..in many individuals there is class I on one side and class II on other..Both are considered stable relations.I wanna ask you some questions to diagnose it better:- 1) Due to have any mouth breathing or tongue thrusting habit? 2) Due you have lack of overbite or open bite? 3) is the spacing between your teeth increasing as per your observation? 4) Due you have any missing lower incisor? 5) Do share your lower arch pics wearing a cheek retractor if possible

With out clinical examination it is difficult to suggest you any treatment. Consult a dentist or orthodontist and periodontist they will give you a best treatment plan.
