Help on my missing tooth please?

I have a missing front tooth and its bothering me a lot when i speak or smile. i have a denture on but i would not like it to be permanent, as i do not think my future partner will like it. Due to the missing tooth, the part of gum with the missing tooth is quite visibly darker than other parts of the gum where it wraps around tooth, hence stretched and visibly lighter. The upper edge of the fake tooth is protruding as it is not underthe gum but slightly outside. I'm currenlty considering a bridge but unsure if it will still look unnatural like dentures or perfenctly natural. Therefore, i appreciate your advices in clearing my doubts. thanks
