Dental Sealants
A dental sealant is a clear or a tinted plastic protective coating that is painted onto chewing surfaces of the back teeth such as the molars and premolars. This is where most cavities form so extra protection is needed.
Molars and premolars have grooves and crevices where food can get stuck. Dentists may refer to these crevices as pits or fissures. These crevices are so deep that the bristles of a toothbrush may be unable to reach them during brushing. Pits and fissures provide the perfect environment for bacteria to grow. When bacteria grow, they form cavities. Sealants can prevent these cavities from materializing. They will cover the grooves and crevices so that food can not enter. Thus, preventing the growth of bacteria and resulting cavities.
What are dental sealants used for?
Dental sealants are most commonly applied to the teeth of children in order to prevent the onset of cavities. Not only are sealants very effective, they also cost less than filling in cavities. As the old saying goes, prevention is better than cure.
Dentists recommend that these sealants should be applied to each molar as soon as possible. This can be done when the tooth has partially erupted into the mouth. However, this can only be done if the tooth can be kept dry and free of saliva during the application of the sealant.
If your child is at a high risk for cavities then your dentist may decide the seal the child's premolars or bicuspids as well. The premolars are your teeth that are directly in front of the molars.
Dentists do not normally suggest sealants for baby teeth however, if the child is at a high risk of developing cavities or is at a high risk of dental disease then sealants may be applied. Sealants are normally used for adults who are at an increased risk of developing cavities. Your dentist can recommend whether such procedure is right for you.
How do you prepare for the application of sealants?
Applying sealants is a quick and painless procedure that can be done during routine dental visits. No injections are needed but the child must be able to sit still during the treatment period. The tooth being worked on must be kept dry. This will allow the sealant material to adhere properly to the tooth.
How are sealants applied to the teeth?
First, the dentist will remove any food or debris in the area. They have to make sure that the teeth are dry so that the sealant will be able to stick. Then, the sealant is applied in liquid form and it flows over and into the pits and fissures. It takes around one minute for the sealant to completely harden. It can also be set using a special light.
What happens after the sealants are applied?
Studies show that sealants can last for a very long time. In some cases, they can last for up to fifteen years. However, keep in mind that these sealants are made out of plastic and can not last forever.
Your child's dentist can check the sealants during your child's routine check-ups and if necessary, the sealants will be replaced. Remember that sealants can work well but they are not a guarantee that your child will be cavity-free. Good oral care at home is important. Adults who have received sealants should continue to practice good oral hygiene by brushing twice a day, flossing everyday, and visiting the dentist on a regular basis.
You can help your child brush their teeth by giving them pea-sized toothpaste servings for every brushing. You can assist them by flossing between teeth that touch each other. Make sure that your child is getting the right amount of fluoride. You can check whether your child is drinking fluoridated water and supplement their fluoride requirements through fluoride tablets or other fluoride products like toothpaste and mouthwash. You must make it a point for your child to see the dentist on a regular basis as well.
What are the risks associated with sealants?
It is very rare for children to be allergic to plastics and certain components. There are some cases where children and adults have adverse reactions to the sealants in their mouth.
When should you call a professional?
You should talk to your dentist and find out about the benefits of using sealants on your teeth. Most pediatric dentists will use sealants on a regular basis while some other dentists would not. Opinions will vary and you should consult with your dentist to find out whether sealants are right for you.
