Crown lengthening aims to extend the natural surface of the tooth.
You might need a crown lengthening treatment because you need another treatment, such as an implant or a bridge, and it’s necessary to extend the surface of the tooth to successfully perform such a treatment.
Another reason why you might be considering crown lengthening is because of a ‘gummy smile’. If you feel like too much of your gums are on show when you smile, then this can have a detrimental effect on your self-confidence. A crown lengthening treatment could rectify this.
