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.

5 Things Your Smile Says About You…

Feeling happy? Go ahead and smile — but know that you may be telling others more about yourself than you think.

The meaning of a smile changes depending on the social context, studies show. Some smiles bring benefits, but others reveal hidden weakness. Humans smile more depending on who they’re talking to, and those smiles can hint at their futures.

Without further ado, here are five things your smile tells others about you.

1. Will your marriage last?

Wedded bliss may be linked to an easy grin. According to a study published in 2009 in the journal Motivation and Emotion, the way people smile in old photographs predicts their later success in marriage.

In one study, psychologists rated people’s college yearbook photos for smile intensity (muscle stretching around the mouth and eyes). They found that none of the biggest grinners divorced later in life. In comparison, 25% of the most straight-faced experienced divorce.

A second study of childhood photos of people over age 65 found a similar link. Among those with the biggest smiles in the childhood pictures, 11 percent later experienced divorce, compared with 31 percent of the least smiley.

A bigger smile may reflect a happy-go-lucky approach to life, the researchers reported. Or bigger smiles may attract a happier partner, and lead to a happier relationship.

2. How fertile are you?

A healthy smile can reflect your overall health, multiple studies show. For women, smiles can even reveal fertility.

Women with gum disease take an average of two months longer to conceive than women without, according to research published in 2009 in the US Journal of Obstetrics and Gynecology. Gum disease is linked to an increased risk of heart disease, Type 2 diabetes, respiratory disease and kidney disease. The link appears related to increased inflammation that accompanies gum disease, the researchers found.

3. How much earning power do you have?

A teenager’s grin can predict how much cash he or she will rake in as an adult. According to a study published in 2012 in the journal Proceedings of the US National Academy of Sciences, happy teens earned 10 percent more income than average at age 29, while gloomy adolescents earned 30 percent less than average at that age.

Happiness is likely linked with fewer worries and less stress, study researchers reported. Less worry means more mental space to focus on job-related tasks.

4. How powerful are you?

Smiles aren’t just about happiness. They’re also a sign of social status. A 1998 study in the journal Personality and Social Psychology Bulletin found that high-powered people, as well as people interacting with others of equal power, smiled when they felt happy.

In contrast, people with less social power than the person they were interacting with smiled regardless of their own emotions.

The findings suggest that powerful people have the privilege of smiling when they please, whereas those with less power are obligated to smile in order to ingratiate themselves.

5. How good a fighter are you?

The link between smiles and power holds in the physical realm, as well. In one study, professional mixed martial arts fighters who grinned in photographs taken the day before a match were more likely to lose than fighters who presented a tough mug for the camera.

Fighting is about dominance, and smiles may inadvertently signal that a person is less dominant, hostile or aggressive, researchers reported online Jan. 28, 2013, in the journal Emotion.

Even untrained observers caught on to the message in the smiles, the same study found. People viewed a fighter as more trustworthy and agreeable, but less aggressive and less physically dominant, if they saw him smiling versus posing with a neutral expression.

The takeaway? Smiles grease the social wheels in most situations, and happiness is usually a boon. But if you’re going head-to-head in a contest of dominance, put your game face on.
