Uneven teeth can generally be resharpened if there are sharp edges or if there is bite trauma. Other than that, teeth resharpening is generally not recommended. Teeth themselves are not completely flat, cuspids, back teeth, etc. will have cusps, and the molar facets will have a large number of ridges and fossae, which are convenient for chewing and grinding food, and do not need to be flattened. However, there are some cases where tooth abrasion has resulted in sharp edges, which may cause traumatic ulcers, or occlusal trauma such as early contact or interference of the teeth, then tooth resharpening is generally possible. Other than that, teeth resharpening is generally not recommended. Uneven teeth are recommended to go to the hospital in time, under the guidance of the doctor to give targeted treatment or treatment.
