Children’s teeth are young and new, but Dr. William D. Steinhauer knows that they are also very vulnerable to cavities. This is why he provides a dental sealant in San Antonio, Texas. A sealant is a plastic barrier applied to the chewing surface of the teeth in the back of the mouth, which are more susceptible to decay. Call Dentistry for Children to learn more about how our dentist can protect your child’s smile with dental sealants.
