What are Fissure Sealants

What are Fissure Sealants?

What if you could prevent tooth decay from forming in your own or your children’s teeth and avoid having to endure the dentist drill? Preventing tooth decay before it appears can mean less pain and less money spent in the long run. Proper brushing and flossing are essential to removing plaque on the smooth surfaces of teeth to help keep your mouth cavity free. But did you know that the indentations on the chewing surfaces of the back teeth, called pits and fissures, are one of the most common places that tooth decay occurs and also one of the most difficult to clean properly? Toothbrush bristles often cannot reach the tiny grooves in these teeth to remove plaque effectively. How can we prevent decay from occurring in these pits and fissures that our toothbrushes cannot reach? One effective solution is a dental sealant.

What are dental sealants?

A sealant is a plastic film-like material that is applied to the chewing surfaces of the back teeth. The plastic material bonds to the pits and fissures of the teeth and acts as a barrier to protect the teeth from decay causing bacteria.

Who can benefit from sealants?

At Reva Dental Kilkenny sealants are most often recommended for children who have newly erupted permanent teeth. First and second permanent molars erupt into the mouth at about ages 6 and 12 years. Having sealants applied to these teeth shortly after they erupt protects them from developing cavities in areas that are difficult to clean. Adults who have existing pits and grooves in the biting surfaces of back teeth may also benefit from sealants. Also, individuals who experience frequent dry mouth may benefit from the extra protection of sealants since their teeth are often deprived of the protective benefits of saliva, which makes them especially vulnerable to cavities.

How are sealants applied to teeth?

Sealants are applied by your dentist and the procedure is simple and fast with very little, if any, discomfort. First, the teeth to receive the sealants will be cleaned and thoroughly rinsed. An acid solution or gel will then be applied to the tooth to help the sealant bond with the tooth. The sealant material will then be painted onto the teeth, much like nail polish on a fingernail, and allowed to dry and form a bond on the chewing surface of the tooth. Your dentist may use a special curing light to help the sealant material harden. It generally takes only a few minutes to seal each tooth. Once applied sealants can last from five to ten years.

How effective are sealants?

Because sealants act as a physical barrier to decay causing bacteria, sealants are nearly 100% effective in protecting teeth from cavities in pits and fissures if applied properly. A systematic review of 16 studies found that permanent molar teeth with sealants had almost 80% less tooth decay on the biting surfaces than teeth that were not sealed. Dental sealants are also cost effective (please see a list of our fees here). Having sealants applied is less than the cost of having a cavity filled.

At Reva Dental we believe that prevention is the key to keeping your mouth and teeth healthy. Be sure to brush twice a day with fluoride toothpaste containing at least 1000 parts per million of fluoride, clean between your teeth daily with floss, eat healthy foods, and visit your dentist regularly.

Taking care of your child’s teeth

Taking Care of your Child’s Teeth

Ingraining good dental habits in your children will prevent you from having to take too many trips to the dentist later in their lives. It encourages them to value and take care of their own teeth, without you having to stand over them, and leads to good dental hygiene as adults.

Dental Routine for Children

Establishing a regular routine, as with all things child-related, is the key. You can start very early; using a very soft brush to brush your baby’s gums when you bath them, and no doubt they’ll want to have a try themselves as time goes on. Supervise them closely, and brushing then becomes established as part of the washing routine in your child’s mind.

Caring for Milk Teeth

Once the first milk teeth begin to appear (usually around 6 months old, but all children vary) you can use a soft brush with some tap water.

Ask your dentist at Reva Dental about using children’s toothpaste; some schools of thought suggest not using toothpaste at all until the child is over two years of age.

Once your child does start using toothpaste, be it a tiny amount of the family brand or a special child’s toothpaste, it should have an appropriate fluoride content.  The fluoride element is important; it should be at least 1,000ppm (parts per million) to be effective in the prevention of tooth decay.

Having their very own toothbrush (child-size, with soft bristles) allows the child to feel accountable for brushing their own teeth; something they will enjoy doing themselves if you encourage them.

Effective Method of Brushing

Watch over them as they brush; make sure you control the amount of toothpaste that goes on the brush, and brush the teeth for at least two minutes before bed and at some other point in the day.

Guide your child’s movements to ensure they brush properly, watching themselves in a mirror helps to brush up and down. They should spit out the excess toothpaste from their mouth but don’t rinse with lots of water. Keep your child on front of the sink until they’re finished brushing, as running around with a toothbrush in their mouth is unsafe.

You should take your little boy or girl to the dentist by age two, so that they are comfortable in the environment and get to know your dentist. Any early problems can be identified quickly, so preventative care can start as soon as required.

Fissure Sealants

A Fissure Sealant can be done once your child’s permanent teeth have started to come through (usually at the age of about six or seven) to protect them from decay.

It involves using a special plastic coating applied to the chewing surfaces of the back teeth to keep food particles and germs out of the teeth grooves.

Dental sealant can last from 5-10 years. The very thin plastic resin bonds well to the surface of the tooth, eliminating any fissures by filling them before cracks set in.
