Benefits of Dental Sealants for Adults

Dental sealants are a valuable tool in the fight against tooth decay, but they're typically associated with issues common to children and young adults. What about older patients? Do they work the same way? These are just a couple of questions you should ask when pondering dental sealants for adults.

What Is a Dental Sealant?

According to the American Dental Association (ADA), the purpose of a dental sealant is to prevent cavities by acting as a barrier. The sealant is a plastic material that covers a tooth's chewing surface, and is commonly applied to premolars and molars – the two surfaces where decay occurs the most.

No matter how well or often you brush, toothbrush bristles can't penetrate all the grooves and depressions located on your teeth's chewing surfaces. Most unreachable spots are primed for plaque and food particles to collect. The dental sealant prevents decay from developing in these vulnerable areas.

Applying the Sealant

The American Dental Association (ADA) suggests sealant application is a simple, painless process:

  1. First, the tooth's surface is cleaned and dried.

  2. Then, an "acidic gel" is applied briefly to roughen the tooth surface to help the sealant adhere to your natural tooth.

  3. Shortly after, the dental hygienist will rinse the gel and dry the tooth before applying the sealant.

  4. After the water rinse, the tooth surface is dried and the sealant is applied. A blue light is then used to solidify the sealant on to the tooth.

Why They're Helpful

Despite being recognized as a procedure geared toward children, there are some unique positives to dental sealants. Regardless of age, everyone is susceptible to tooth decay. Sealants can therefore decrease this occurrence in anyone who chooses to receive them. Sealants also prevent food and plaque from gathering in grooves and depressions on tooth surfaces, further reducing one's risk of decay as the sealants leave bacteria no place to grow. Ultimately, dental sealants are a great form of preventive maintenance. Spending a little money upfront ensures neglected areas won't result in costly dental procedures down the road.

When to Think Twice

Despite the benefits of sealants, there are some downsides as well. One of them is short-term cost. Although sealants can save you money down the line by proactively protecting your teeth, there's still the upfront expense of the procedure. Sealants also aren't permanent; they'll need to be reapplied every 10 years.

Tooth Decay Prevention

Of course, dental sealants for adults aren't the only way to fight tooth decay. Some of the smartest and easiest ways to stay healthy are also the most sensible ones. Brushing and flossing multiple times a day, and using a toothpaste such as Colgate® Enamel Health Whitening Toothpaste, will always be your first line of defense. Meanwhile, eating nutritious foods should be an equally prominent part of your oral health plan.

What to Expect During a SEALANT Procedure

Placing dental sealants is usually painless and doesn't require drilling or numbing medications.

  1. Tooth preparation – first, the dental hygienist will polish the surface of the tooth to remove plaque and food debris from the pit and fissure surfaces. Next the hygienist will isolate and dry the tooth. Then the hygienist will etch the surface of the tooth, rinse off the etching material and dry the tooth.

  2. Sealant application – the hygienist will apply the dental sealant material to the surface of the tooth with a brush; a self-curing light will be used for about 30 seconds to bond the sealant to the tooth surface.

  3. Evaluation – finally, the dental hygienist and dentist will evaluate the dental sealant and check its occlusion. Once the dental sealant has hardened it becomes a hard plastic coating, and you can chew on the tooth again.
