Is there a cheaper way to get the gaps between your teeth closed
Other than braces I don't know of anyway to.
The cheapest way to close the gaps between your teeth is by use of teeth gap bands or the use of braces. Bonding, porcelain veneers and invisible orthodontistry are other cheap methods you can use to close the teeth gaps.
Calk for your sink or bathtub works best. Just squirt some into the gap and smooth it to get the shape and texture you want. Way faster and way cheaper than braces.
