If you’re like many adults today, you have your share of cavities, most acquired during childhood. And, like many adults, you probably have some not-so-cherished memories of the drilling, and the stuffing, and the discomfort that can accompany getting a filling. Filling cavities in our teeth is important, but it can’t quite be called fun. And it’s not a sign of healthy teeth, either. Cavities signal tooth decay, but how can you keep that decay away? Call on dental sealants.
Do Dental Sealants Help Prevent Cavities?
Brushing your teeth and flossing daily removes most of the food and bacteria from your teeth. But not all of it. Especially on teeth in the back of your mouth — molars and premolars. These are the teeth that do most of the work, the grinding and chewing, when you eat. And the surface grooves and fissures —which all teeth have — are deeper on these teeth than on others, and harder to reach when you brush, especially for young children.
Dental sealants consist of a thin coating of liquid plastic that’s painted onto the chewing surface of molars and premolars. They serve as an extra barrier to help protect these hard-working teeth from decay. Sealants work much like the commercial packaging we find on perishable foods in a store. They keep food particles, bacteria, and plaque from settling into the hills and valleys of your tooth’s surface in the way that a package, be it a can or a bag, keeps dust and dirt out of the food on your grocer’s shelves.
Dental sealants are permanently bonded to a tooth’s surface. To apply a dental sealant, we first use an acidic solution to roughen the surface of the tooth so that the sealant solution will stick as well as possible. Once the acid is rinsed off, the sealant is carefully painted onto the surface of your tooth. As the sealant is applied, it flows into all the crevices in the tooth, some of which are thinner than a strand of human hair. The final step is hardening the sealant, called polymerizing, accomplished by shining a curing light on the tooth for a few minutes.
Their application takes little time — most often less than 45 minutes — and helps ensure that your tooth will be ready to keep out bacteria and food particles for years to come. And it’s usually painless, a plus for children who fear the dentist or people who have particularly sensitive teeth.
How Well Do Dental Sealants Do Their Job?
Keeping cavities out of teeth in order to avoid the need for a dental filling is one of the main jobs dental sealants are specifically designed to do. Although they are most often used on children’s teeth, sealants can work well for adults, too. The statistics are impressive:
According to the American Dental Association, sealants can not only prevent cavities, but they can also sometimes halt the progression of tooth decay that has not yet created a cavity.
Is The Cost of a Dental Sealant Worth It?
Typically, placing dental sealants will cost from $30 to $60 per tooth, depending on the teeth, your overall oral health, and the number of teeth to be sealed. Most dental insurance plans either don’t cover sealants at all, or offer minimal coverage. Nevertheless, even without dental insurance, sealants are likely to be less costly in the long run than handling tooth decay by putting in a filling.
The initial cost of filling a cavity is significantly more than the cost of a dental sealant. A filling can cost as much as $150 depending on the size of the filling needed and the type of filling desired. And cavities, and the need to fill them, are not uncommon. According to Zentist, a dental insurance website, on average:
42% of children age 2 to 11 have cavities in their primary teeth
59% of adolescents age 12 to 19 have cavities in their permanent teeth
92% of adults have at least one cavity
Even if cost isn’t an issue, time and inconvenience often are. At the least, like getting a dental sealant, filling a cavity means a visit to your dentist. But getting a filling takes longer, can be uncomfortable during the procedure, and may cause pain (from mild to severe) that keeps you from your normal activities for the rest of the day. Sealants can be applied rather quickly, compared to filling a cavity, and they usually cause no pain or discomfort. And, unlike replacing a filling, which requires re-drilling the tooth, if a seal is broken, for whatever reason, the sealant can easily be reapplied.
As with any oral health decision, the real first step to stopping cavities with dental sealants is to talk with your dentist. We at Lifetime Dental Health are here to help, right from the start.
