Not very knowledgeable about cars in general. Would this be enough to buy a new battery? My car has been giving me Mass Airflow Sensor error codes and I’ve cleaned the MAF sensor and still has the same issue. Could this be the problem? 2019 Nissan Altima SR

I noticed there is a space between my teeth and the aligner. Is this normal? It’s my third day on Tray 9. I have also been chomping on the chewies.
