At Dr. Ricky Leung’s clinic, we treat dental problems as well as prevent them from happening, when possible. Dental Sealants are one of the preventive services we offer. They are thin, plastic coatings painted on the chewing surfaces of your back teeth (premolars and molars). Back teeth often have pits and grooves, which can’t be reached easily with a toothbrush. Over time, these grooves will store food and bacteria that might lead to tooth decay and other dental problems. As a preventive measure, we seal those pits and grooves with dental sealants, keeping your teeth healthy and decay-free for life. Dental Sealants are highly effective with children because they keep their teeth healthy and decay-free from a very early age.
