Dentist NYC: Minimally Invasive Dentistry

What is minimally invasive dentistry?

Minimally invasive dentistry is a philosophy that is adhered to at Sachar Dental NYC. In general terms, minimally invasive dentistry is the belief and application that we always prefer and perform the least invasive, and the most conservative dental treatment options available for any given problem. It is a philosophy that we have adhered to at all times for the past two decades.


Going into more detail, there are many ways that we apply this philosophy.  We believe in having “respect for the original tissue”. We use this philosophy with all of the invasive procedures that we perform at Sachar Dental NYC. We always try to reduce the amount of drilling or filing of the natural tooth structures as much as possible. At the same time, we are able to solve virtually all problems presented to us, while remaining conservative.


This also applies to a strong emphasis on prevention rather than cure. We always try to identify and manage dental disease processes in their early stages, before more invasive procedures become necessary. For example, we encourage our patients to adhere to a strict schedule of coming in twice a year for their dental teeth cleanings and dental checkups in order to catch problems early before we need to perform invasive procedures.  Another good example of the application of this philosophy, is “re-mineralization”, rather than drilling for a cavity.  See “re-mineralization“ below for more details.

Dentist NYC - Minimally invasive dentistry techniques include:

Dentist NYC: Tooth Colored Resin Fillings

At Sachar Dental NYC we always perform the least invasive dental procedures possible. Minimally invasive dentistry was not always an option. The invention of tooth-colored, resin-type fillings, that replaced silver, amalgam fillings played a big part in the origin and philosophy of minimally invasive dentistry.  In the past, in order to fill a cavity with silver amalgam fillings, we had to rely on “mechanical retention “.  This simply means that the shape of the area of the tooth that we drilled had to be wider and deeper in order to be able to hold a filling inside. The filling had to be wider at the deeper aspect, than at the superficial aspect.  The amalgam filling would then not be able to come out of its cavity due to its shape.  Newer, tooth-colored, resin fillings rely on a chemical bond between the filling material and the tooth.  This produced a huge advantage in dental fillings.  It allows us to remove much less of the natural tooth because we do not need to have that wider part drilled in order to retain the filling.  We are able to remove only the decayed parts of the tooth, and a resin filling bonds to the tooth, and does not fall out.

These technological advances in dentistry allow our NYC dentist to remove as little of the natural tooth as possible for cavity fillings. This allows for the filled tooth to be stronger and last longer.

Dentist NYC: Dental Re-mineralization

At Sachar Dental NYC we believe in preventative dental medicine. The disease process of dental cavities forming in our teeth starts with the de-mineralization of the tooth enamel causing the surface of the tooth to become softer.  In the very early stages of cavities forming, this process can be arrested through re-mineralization.  In these early stages, the cavity is only present superficially in the tooth enamel.


Re-mineralization is done by the topical application of fluoride.  By restoring minerals in the tooth, this can help to restore the strength and hardness of the tooth enamel, and also stop the cavity from getting larger.  Re-mineralization can repair the damage created by the de-mineralization process on the surface of the enamel.


For example, when patients come in with small dental cavities that are only in the outer surface of the tooth enamel, it is our philosophy to first treat these patients with a fluoride treatment, rather than to drill the tooth and place a filling.  In our experience, many patients respond to this treatment and never need to have the cavity filled.  We then check every 3-6 months at your normal routine checkup and monitor the area.

Dentist NYC: Dental Sealants

Dentist NYC for Dental Sealants

At Sachar Dental NYC we always use the least invasive dental procedures possible. We believe prevention is better than cure. When we identify deep grooves or depressions in the teeth that may harbor bacteria and lead to tooth decay in the future, we will often recommend a dental sealant procedure.   Dental sealants are made out of a resin that is similar to tooth colored filling materials.  Dental sealants fit into these grooves and depressions and protect the tooth by acting as a barrier for the build-up of plaque, bacteria and tartar.  Dental sealants are usually used on children, but can be used on adults as well.  The application of dental sealants does not require any drilling of the teeth. It is a preventative procedure.

Dentist NYC: Porcelain Dental Inlays and Onlays

Dentist NYC for Inlays Onlays

At Sachar Dental NYC we always try to maintain as much of the natural tooth as possible. Tooth decay and dental cavities are often identified when they are very large, and are sometimes too large to be filled with traditional cavity filling materials.  At this stage, we will make the decision whether to perform an inlay or onlay porcelain filling, or to use a crown.  The application of a crown requires removal of much more of the natural tooth than the inlay or onlay porcelain fillings do.


By using an inlay or onlay porcelain filling, we are able to save more of the natural tooth.  The inlay porcelain fillings consist of a custom fabricated piece of porcelain that is made in our dental laboratory. It is permanently bonded to the tooth in order to fill a large cavity.  An inlay porcelain filling is utilized when the cavity lies within a tooth, and it is surrounded by healthy tooth structures on all sides. An onlay porcelain filling is similar to an inlay porcelain filling, however, it is used when one or more of the outer parts of the tooth are affected by decay or trauma.  Both inlay and onlay porcelain fillings are more conservative and require removal of less of the natural tooth structure than placing a crown on the tooth.

Dentist NYC: Mouth Guards

Dentist NYC for mouthguards

At Sachar Dental NYC we always try preventative measures before treatment is necessary. Mouth guards are an excellent example of using preventative measures before damage to a tooth occurs.  Many dental problems can be attributed to clenching and grinding of the teeth.  There are many reasons why patients may clench or grind their teeth.  Patients that clench or grind their teeth usually do this at night while there are sleeping, and unaware.  Clenching and grinding can cause wearing away of the tooth enamel.  In later stages, this can result in chips, fractures and cracks in the teeth.  It can also result in temporomandibular joint (TMJ) pain.


The use of a night guard protects the teeth before damage can occur, to the teeth or the TMJ joint.  Mouth guards are custom made by taking a mold of your teeth.  They are made of durable materials that last for a long time.  At Sachar Dental, our top rated NYC dentists only use BPA-free materials when fabricating our mouth guards.
