Gap between teeth?

My 8 month old has his 2 front teeth in but it looks like he's going to have a gap between them because I can see the string that comnects his lip to his gums is separating them. There's a couple people in my family that have a gap too but they hate it and wish it had gotten fixed. How would I go about getting his lip tie clipped? Do I have to wait until he's older?
