Did you know that tooth decay ranks as the most prevalent chronic childhood ailment? Surprisingly, it surpasses conditions like asthma and diabetes in prevalence! According to The National Institute of Dental and Craniofacial Research, nearly 45% of children aged 2 to 11 have experienced at least one cavity. Despite diligent efforts to instill good oral health habits such as daily brushing and flossing, children's teeth can still be susceptible to damage. Fortunately, dental sealants offer a protective measure against tooth decay, addressing common queries surrounding this dental treatment.
#1. How Do Dental Sealants Function? Dental sealants entail applying a thin, BPA-free protective coating to the chewing surfaces of molars and premolars. This sealant acts as a barrier, shielding teeth from bacteria, food particles, and acidic substances that can accumulate in the small pits and grooves. By creating this barrier, sealants significantly reduce the risk of tooth decay.
#2. Who is Eligible for Dental Sealants? While both children and adults can benefit from sealants, it's typically advisable to undergo treatment during childhood, before the onset of tooth decay. Coating molars with a protective seal at a young age can effectively prevent cavity development. In fact, studies suggest that dental sealants can prevent over 80% of cavities in permanent molars two years post-treatment.
#3. How Are Dental Sealants Applied? The process of applying dental sealants is swift and painless. First, the teeth are cleaned and dried, followed by the application of an acidic gel to roughen the tooth surface, facilitating a stronger bond with the sealant. After a brief interval, the gel is rinsed off, and the teeth are dried again. Subsequently, the sealant is painted onto the chewing surfaces of the teeth and hardened in place using a special light. The entire procedure typically lasts only a few minutes.
#4. What is the Lifespan of Dental Sealants? Generally, dental sealants can last up to ten years before requiring reapplication. During your child's biannual dental checkup, the dentist will assess the condition of the sealant to determine if reapplication is necessary to maintain optimal protection for their smile.
