Great you used a mouth mirror to share a clear image!
It seems you might have some dental awareness/background as you used the word " impaction "too.
In my opinion ,since the upper left wisdom tooth is partially erupted ,carious and impacted against upper left 7,it would be better to remove it ,as it is inaccessible for cleaning and filling and can cause distal decay in 7(upper second molar tooth)if left for long.
Next Steps
Schedule a dental evaluation
