Dental fillings are a type of restoration most often used to treat cavities or repair broken or cracked teeth.

When is a Dental Filling or Tooth Filling Needed?

A dental filling is a type of restorative dentistry treatment used to repair minimal tooth fractures, tooth decay or otherwise damaged surfaces of the teeth.  A filling can allow a tooth to regain normal shape and function. At Dr. Linger’s office in Charlotte, NC, we offer tooth filling services to patients in need of an affordable restoration.

Even with daily brushing and flossing, tooth decay can develop. Upon realizing that a cavity has formed, you’ll want to quickly have the decay removed and the tooth filled to prevent the cavity from getting larger.

Enamel loss is a common component of tooth decay, and may result in tooth sensitivity. In many cases, sensitivity caused by enamel loss will be significantly improved or completely eliminated once an appropriate dental filling material is placed. 

But in some cases, depending on the extent of tooth decay or damage, the affected tooth may require additional or alternative procedures, including:


  • Dental Crowns: Teeth requiring more support than offered by a traditional filling may require a dental crown.
  • Dental Implants and Dental Bridges: Irreparable tooth damage requiring tooth extraction may require an implant or bridge.
  • Root Canals (perhaps along with antibiotic treatment): Infected, abscessed or nerve damaged teeth may require a root canal procedure.


Fillings and Dental Work

Following a professional cleaning, X-rays and a review by Dr. Linger, you will then be consulted with on the health of your teeth. Dr. Linger will explain and show you any cavities that he wants to “watch” or suggest having filled. Dr. Linger also uses fillings to repair any cracked or broken teeth and teeth that have been worn down over time.

The Procedure

Dr. Linger will begin the procedure by preparing the tooth and necessary surrounding area in order to restore the decay or damage. The decay or damage is removed with a dental laser, and the area is cleansed to remove all bacteria or debris before the restoration is completed.

The first step in performing a composite filling procedure involves isolation of the tooth. Tooth isolation is critical in a composite restoration because it prevents moisture from interfering with the bonding process. This requires the placement of various adhesives followed by the composite material, which is then hardened with a special bonding light. This allows the completed composite restoration to be both functional and natural looking.


Innovative, Modern Dental Filling Procedures

Over 80% of American Dentists are still using the old Silver-Mercury Amalgam Filling Material. However, we do not offer that material in our office. This is one of the main reasons why patients choose us. Dr. Linger has not used Silver Mercury Amalgam Fillings for over 20 years.

Here are some of the reasons why patients choose Dr. Linger’s Method of Dentistry™ for their fillings procedures:

  • They are concerned about the potential Toxicity of Mercury in Amalgam
  • People seeking Holistic Dental Care
  • We provide the most Cosmetic filling treatment available
  • Minimally invasive procedures using the Dental Operating Microscope.

What Types of Fillings are Used?

Dr. Linger uses several choices of dental filling materials that are available. Teeth can be filled with gold; porcelain; or tooth-colored, plastic, and glass materials called composite resin fillings.

Gold fillings – Gold fillings last at least 10 to 15 years, can withstand hard chewing forces, and some patients find gold more pleasing to the eye than silver.

Tooth-colored composite fillings – The biggest advantage to theses fillings are the aesthetics (they look like your teeth), they bond to the tooth structure, and sometimes less tooth structure needs to be removed compared to silver fillings.

Other filling types include porcelain ceramics. Dr. Linger and our staff can discuss all of these available filling types and suggest the best one for your specific need.

How Tooth Fillings Are Placed

Dr. Linger’s Method of Dentistry™ uses minimally invasive restoration of teeth using the Dental Operating Microscope. For this reason, fillings procedures can often be performed without the need for anesthesia.

If anesthesia is needed, Dr. Linger has develop a special method of local anesthesia to make the numbing process as painless as possible. This includes the use of a special gel numbing technique he developed.

Next, the cavity is removed under the microscope using a specialized low noise and vibration dental drill. Developed in Germany, this drill doesn’t use the traditional air driven motor found in most dental drills cause that unmistakable high-pitched noise.

After the decay is removed the tooth is bonded and sealed. Next, using the latest advances in dental composites Dr. Linger places the filling using injection molding. The filling is set immediately with a specialized light.

Recovery and Aftercare

After the cavity has been filled, Dr. Linger will discuss steps you can take to prevent decay from forming under or around the filling, or in other teeth.

Brushing twice a day with fluoride toothpaste and flossing with dental floss or an interdental cleaner once a day is advised. Keep regular appointments for routine check-ups and teeth cleanings. We may also may suggest sealants that can be placed over your molars to prevent the build-up of plaque and decay, as well as the use of fluoride mouth rinses as an additional preventive measure.
