When your gums appear disproportionally large, it can make your teeth seem small. Asymmetrical gum growth can also cause your otherwise uniform teeth to look misshapen. Through a relatively simple procedure, called a gum lift, your cosmetic dentist can gently reshape your gums. This process can then improve the overall appearance of your smile, which can greatly increase your confidence.Most gum contouring can be completed in a single office visit, during which the dentist will numb your gums and then gently re-sculpt your gum line based on how you desire your smile to look.
