Sealing Out Tooth Decay

Due to too much sugar in our diets, 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.

"I was really concerned that my son was developing cavities at such a young age.  I'd watch him brush his teeth and while he appears to be thorough, he simply can't brush his back teeth well without some help.  The dental sealants were easy to apply and help protect all the grooves and pits of the teeth.  I feel better knowing we have an extra defense against future cavity problems!"

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 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 dentist must thoroughly clean and prepare the molars, before painting sealant on the targeted teeth.  

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?

Although sealants are helpful in some baby molars, they are more commonly placed on permanent molars which have much deeper pits and fissures.  

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.

After many years of being self-conscious about my smile due to an overbite and overlapping teeth, I decided to have a consult about having braces (preferably Invisalign). Due to all the correction needed, wire braces were my only option. After 5 years of various correction procedures I am now proud of my smile. Dr. Jeff and the staff were always prompt and very encouraging during each visit.

I had an appointment this morning for a crown prep. I was seated a few minutes before my actual appointment time. I was seen immediately by the assistant who prepped me for my local anesthetic. The anesthetic was given gently and painlessly. When I was thoroughly numb the procedure was started and finished in a shorter time than I had thought it might be. I was happy with all the services I received. Everyone from office staff to those assisting and performing the services were courteous and efficient. Dr. Dahm was his usual friendly professional self. I would recommend this dental practice to anyone needing dental care.

I know, through my own work experience, that working with the public can be trying at times, and sometimes it is difficult not to fall into a "negative" mode, which really does none of us any good. I am not sure whether a "negative" atmosphere shows its face when dealing with people, as much as a "positive" atmosphere does, or not. I am inclined to think not, but anyway, I would like to say that I am proud of everyone in your office, for creating and keeping that "positive" atmosphere, for all of us patients, because it truly does make a difference in the way we feel while we are there, and when we leave the office. I don't ever remember giggling several times during a dentist appointment, but couldn't help myself yesterday morning, as Dr. Dahm moved through the office, greeting, reassuring, and caring for people. The girls who helped me through the x-rays, molds, and other necessary procedures were awesome, as well! "Good Job", "You're doing great", etc., while in a place where most people are a little uncomfortable, at best, is so nice to hear. And, when I was confused about just where in my mouth my filling would go, the girls were so kind in explaining that they really were going to work on the correct tooth. LOL! I am running on here, but I think too often in business, the main feedback that people get, is the negative stuff. I have always tried to counter that, by letting people know when I really do appreciate what they have done "for" me, instead of "to" me, and I will be the first to admit that trust does not always come easy for me - just the way I am. And, I feel that an establishment's "true colors" show in instances like I had yesterday, when I needed some reassurance that everything was okay. I am so appreciative of the way everyone handled that (sorry that I took up precious time), but now I know, that if/when I truly do need help, it will be there, and given in a kind and understanding manner. That means a LOT to me! So, in closing, in the middle of the night, during my usual "awake" time, I just kept thinking WOW! I just don't know of a better way to express my feelings! And, of course, THANK YOU to everyone in that office, because it takes every person in an environment like that to maintain a caring and positive atmosphere! I notice and I appreciate all of it, and I would recommend anyone I know to become a patient there!
