Ideally, your gums should nicely frame your teeth, showing just the right amount of each tooth. However, some people have what’s called a ‘gummy’ smile, where they will show too much gum tissue whenever they smile or talk. Often the tooth underneath the gums is exactly the right shape but is simply covered up with an excess of gum tissue. This can detract from an otherwise attractive smile and is often easily corrected with a crown lengthening treatment.
