What is a sealant?  

A sealant is a tooth-colored resin material that is placed on chewing surfaces of teeth to help them stay cavity-free.

Why do teeth need sealants?

Molar and premolar teeth often have very deep pits and fissures.  While bacteria can easily enters these groves, toothbrush bristles are often too large and therefore ineffective.  As a result, these areas become the perfect breeding ground for bacteria to multiply which can lead to dental decay. A sealant does just what its name suggests…it seals off the grooves so that bacteria can’t enter.  After a sealant is placed these areas can no longer harbor bacteria and your tooth brushing once again becomes effective.

What teeth need sealants? 

Any teeth that have deep groves or pits can benefit from sealants.  These are most often found on molar and premolar (teeth right in front of the molars) permanent teeth, but varies from one individual to another.  One person might benefit from sealants on all molars and premolars (16 teeth), while another may only need their molars (8 teeth) sealed.

Once a tooth has a dental filling in it, it no longer benefits from a sealant.

People often think that only children benefit from sealants.  That is because sealants are typically placed on a child’s molars when they first erupt.  The reality is that any teeth with deep pits and fissures (that do not already have fillings) can benefit from sealants because they  will help prevent future cavities.

How is a sealant applied?

No tooth structure is removed in order to place a sealant.  Instead it is kind of like painting your fingernails: resin material is only added, nothing is taken away.  The tooth is thoroughly cleaned with a pumice and etch.  The tooth is then washed thoroughly. Finally, the sealant material is applied and then cured with a light in order to harden it.

Sealants typically last two to five years.  Although, it is not uncommon to see sealants in adults that were placed in childhood and are still intact.

Avoiding sticky, chewy, and hard foods can potentially prolong the life of a sealant.

If a sealant is no longer fully intact then it is no longer effective and should be replaced by your dentist.  If it has been less than two years since the sealant was placed, ask if your Apex family dentist offers a warranty for sealants.

The Importance of Replacing Missing Teeth from an Apex Emergency Dentist

Everyday we see patients that have missing teeth. Sometimes they are teeth that have been recently extracted.  Other times they have been missing for years.  The reasons for why the teeth are missing vary.  But the answers about why to replace them are usually the same.  So we wanted to share these answers with you!

In the US, about 70% of the population is missing one or more teeth.  Tooth loss can lead to reduced self confidence because of gaps in a person’s smile.  Unfortunately, effects on physical appearance are not the only result.

 

Teeth are lost or missing for several reasons such as trauma, decay, periodontal disease, or even genetics.  It is important to replace missing teeth because when a tooth is missing there is no contact with the opposing arch.  This can cause opposing teeth to gradually extrude which leads to other problem, such as fractures, mobility, tooth loss, shifting in surrounding teeth, and gum problems.

There is more than one option available to patients for replacing missing teeth.  Like most choices, each option has pros and cons.  The 3 most common options are replacing the missing teeth with implants, crowns and bridges or dentures. Sometimes a combination of two of these options can be used, such as a denture that is supported by implants, or a bridge that is supported by implants.  We will cover more about what the pros and cons of each of these treatments are in upcoming blog posts.

“An ounce of prevention is worth a pound of cure”, so whenever possible try to avoid loosing the tooth in the first place.  The financial cost of saving a tooth with a crown or even a crown and a root canal is substantially less than the cost of an implant and crown or a bridge.  Not to mention that by saving one tooth, you are also helping keep the surrounding ones healthy as well.

The loss of a tooth is not always preventable, such as in the case of trauma or when a tooth is congenitally missing.  But no matter the cause, it is important to understand the effects of missing teeth so that you can take the necessary steps to prevent further problems. Your Apex dentist can answer questions you have about what treatment best fits your needs and your smile.  And check back here when we explain more about each treatment in the upcoming weeks!
