Sealing Out Tooth Decay

Tooth decay has become increasingly prevalent in preschoolers.  Not only is tooth decay unpleasant and painful, it can also lead to more serious problems like premature tooth loss and childhood periodontal disease.

Dental sealants are an important tool in preventing childhood caries (cavities) and tooth decay.  Especially when used in combination with other preventative measures, like biannual checkups and an excellent daily home care routine, sealants can bolster the mouth’s natural defenses, and keep smiles healthy.

How do sealants protect children’s teeth?

In general, dental sealants are used to protect molars from oral bacteria and harmful oral acids.  These larger, flatter teeth reside toward the back of the mouth and can be difficult to clean.  Molars mark the site of four out of five instances of tooth decay.  Decay-causing bacteria often inhabit the nooks and crannies (pits and fissures) found on the chewing surfaces of the molars.  These areas are extremely difficult to access with a regular toothbrush.

If the pediatric dentist evaluates a child to be at high risk for tooth decay, he or she may choose to coat additional teeth (for example, bicuspid teeth).  The sealant acts as a barrier, ensuring that food particles and oral bacteria cannot access vulnerable tooth enamel.

Dental sealants do not enhance the health of the teeth directly, and should not be used as a substitute for fluoride supplements (if the dentist has recommended them) or general oral care.  In general however, sealants are less costly, less uncomfortable, and more aesthetically pleasing than dental fillings.

How are sealants applied?

Though there are many different types of dental sealant, most are comprised of liquid plastic.  Initially, the pediatric dentist must thoroughly clean and prepare the molars, before painting sealant on the targeted teeth.  Some sealants are bright pink when wet and clear when dry.  This bright pink coloring enables the dentist to see that all pits and fissures have been thoroughly coated.

When every targeted tooth is coated to the dentist’s satisfaction, the sealant is either left to self-harden or exposed to blue spectrum natural light for several seconds (depending on the chemical composition of the specific brand).  This specialized light works to harden the sealant and cure the plastic.  The final result is a clear (or whitish) layer of thin, hard, durable sealant.

It should be noted that the “sealing” procedure is easily completed in one office visit, and is entirely painless.

When should sealants be applied?

Sealants are usually applied when the primary (baby) molars first emerge.  Depending on the oral habits of the child, the sealants may last for the life of the primary tooth, or need replacing several times.  Essentially, sealant durability depends on the oral habits of the individual child.

Pediatric dentists recommend that permanent molars be sealed as soon as they emerge.  In some cases, sealant can be applied before the permanent molar is full grown.

The health of the sealant must be monitored at biannual appointments.  If the seal begins to lift off, food particles may become trapped against the tooth enamel, actually causing tooth decay.

If you have questions or concerns about dental sealants, please contact your pediatric dentist.

Testimonials

Dr. Baltazar has been our family dentist for more than 20 years. In all that time, we have received only the absolute best quality care and treatment. His credentials, expertise and reputation are all impeccable.
Whether the treatment plan is simple or complex, he has always taken as much time as necessary to make sure we understand exactly what is to be done and why. We never feel like we're being rushed or being confused by complex technical jargon. One of my fears used to The Needle, but I am still continually amazed by his precise, gentle and deft administration of anesthesia. I actually sort of look forward to it!
His assistants and staff deserve praise, too. Both the front office staff and his technicians are always considerate, cheerful but also knowledgeable. Long-time office manager Cecilia has always been so helpful and friendly to us that we practically regard her as another family member.
Just as we came to Dr. Baltazar's practice by way of an enthusiastic recommendation from a trusted friend, we would not hesitate to recommend him to anyone looking for the best dentist in town.

Dr. B.~ You have set a high bar of expectations for any dentist who treats me to attempt to reach. I cannot thank you enough for all of the outstanding care you have provided to me over these last few years. May the Lord bless you in the next 30 (or however many) years of your practice! With fond gratitude,

Margaret Lowing

You'll not find a more caring, personal dentist around! I've been going to him for over 10 years. My two young daughters even requested to go to him OVER their previous childhood dentist (who had video games and movies playing at all times) which says alot! Dr. Baltazar is a dentist you can trust with yourself and your family!
