Hi Moggie,
From the photo you shared, it looks like you might have a mild to moderate deep bite, where the upper front teeth overlap the lowers more than average. A certain amount of overbite is totally normal, and many people function well even if it's a little more than textbook "ideal."
Since you're not experiencing discomfort and your bite feels natural during daily activities like eating or speaking, it's probably not something that needs urgent correction. Deep bites typically become a concern if they're causing wear on the lower teeth, gum irritation, or jaw issues.
