Dongdaemun SeoulOneTop Dental Clinic applies dental sealants on the 5th floor of 1050 Jegi-dong, Dongdaemun-gu, a 2-minute walk from Jegi-dong Station Exit 2 on Subway Line 1. Sealant material is applied to the pits and grooves of chewing surfaces to reduce plaque and food build-up.

Sealant options
Sealants are usually placed on molars, and on premolars when their grooves are deep.

Depending on tooth anatomy and individual cavity risk, premolars may also benefit from sealant treatment when their grooves are particularly susceptible to plaque accumulation.
