Porcelain & Composite Fillings

Porcelain & Composite Fillings Specialist

Dental bondings and onlays can be a great solution for treating and “hiding” small to large areas of decay. The dentists at 209 NYC Dental in Midtown East rely on high-quality materials, advanced technology, and advanced techniques to create long-lasting restorations for their New York City patients, achieving natural-looking results designed to be virtually undetectable.

Before we can talk about restoring teeth with Porcelain & Composite Fillings, we want to make sure that our patients understand the reasons and necessity for such restorations.

Tooth cavity

The most common dental problem is dental decay.
Dental tooth decay, also known as dental caries, is a lesion formed inside the tooth structure called dentin. Caries can appear in any part of the tooth or on root surface if it is exposed.
The most common place for it to form is the top or bottom (occlusal) surfaces of the back (posterior) teeth inside the crevices of the tooth.
Mesial and distal (interproximal) decay is also common. This cavity is formed between the teeth. The mesial surface is toward the front of your mouth and distal toward the back one.

Ways to prevent decay
There is no magic solution to decay prevention, no red wine, no coconut oil, no other gimmicks, except drinking fluoride water. The rest depends on the consistency and the regularity of your oral hygiene routine.

  • Proper brushing at least twice a day is a number one way to prevent decay formation.
  • Brushing alone is not always sufficient as the bristles of the toothbrush cannot always get in between the teeth to remove all the food particles lodged in there. Thus regular flossing is imperative to preventing interproximal decay.
  • The sealant is a clinical method to prevent occlusal decay from the formation. The sealant is placed either by a dentist or a dental hygienist in the permanent tooth on the occlusal surface before any sign of the decay is present.

Treating tooth cavity

Once the tooth cavity is formed the only way to prevent it from spreading is by removing it from the tooth. Complete removal of the cavity cannot be achieved at home since it requires a use of dental instruments, like drills and other. After the dentist cleans out the decay, the tooth has to be restored using a proper material.

Restorations like dental bonding also known as composite filling and ceramic onlays and ceramic inlays serve the same purpose. They restore teeth that were compromised by the decay. Unlike dental crowns teeth that require restorations with feelings and onlays may have significantly more tooth structure left and have not had with root canal therapy.

Your dentist will advise on the most appropriate restoration type for the compromised tooth based on the size of the restoration needed.

If the decay was small and does not extend over to other surfaces, i. e. only the occlusal or the lingual surface needs replacing composite filling can be an excellent option to restore the tooth.

If decay has extended to several surfaces of the tooth ceramic onlay or inlay often is a better choice.

What is the difference between composite bonding and ceramic onlay or inlay?

Porcelain or ceramic onlays and inlays are custom made in the lab and produced out of the porcelain or ceramic as the name states. Either material is very durable, designed to sustain powerful biting forces and susceptible to withstand temperature changes in our mouth. It also does not change color when exposed to various foods.
It is the same material as used in veneers, crowns, bridges, and implant supported restorations.

Dental bonding, also called cosmetic bonding, composite filling, uses special resin materials to restore damaged teeth. Just like with porcelain the shade of the composite material can match your teeth, so the restoration looks natural. Unlike porcelain, the composite is a porous substance that is softer and gets yellow with time by absorbing the coloring in the foods and liquids we consume. A composite filling is not as durable as a well-placed porcelain or ceramic onlay and therefore not recommended for extensive restorations.

In the past large cavities were restored with amalgam fillings. When dentistry moved towards the mercury free restorations amalgam was replaced with composite. Now with advancements in porcelain and ceramic restorations and improvements in prepping techniques onlays and inlays are a new standard of care.

What happens during dental bonding procedure?

First, decay is completely removed, and the area is cleaned of debris. Then, an etching solution will be applied to the tooth surface to make it rough so the bonding material “sticks” better. Once the tooth surface is prepared, the bonding resin is applied to the area layer by layer to ensure the strongest possible bond as the restoration is “built” on the tooth surface. The resin material is carefully shaped to ensure it looks like your natural tooth. Once the resin bonding material is in place and shaped, a curing light will be used to help strengthen the material, and the resin will be gently buffed for beautiful, natural-looking results that blend beautifully with your other teeth.

What happens during dental onlay preparation?

Dental onlay is a two-visit procedure. The preparation is identical whether you need a ceramic onlay or inlay.
The first visit may require anesthesia. Then the decayed portion of the tooth is removed, and the treatment site is carefully cleaned of debris.
An impression of the tooth is required once the tooth is decay free. In many offices a dentist will use a colorful “putty” that is put on the impression tray, a patient bites on the tray and keeps it in the mouth for several minutes. Then the tray is removed. Often to achieve clear margins, the reline of the impression is required. With additional material placed around the tooth, a patient has to bite again on the impression tray.
Our dentists use a 3D scanner to make digital impressions. The 3D scanners produce impressions fast, more accurate, and without any waste. 209 NYC Dental is proud to be GREEN.
After the impression is made, the dentist chooses the shade of the future onlay matching it to the tooth. The impression and the shade are then transmitted to the lab. The opening in the tooth is restored with a temporary material.
At the second visit, the onlay is cemented to the tooth using a specialized adhesive, then onlay is gently buffed to make sure it fits comfortably.

Dental inlay vs. onlay

These two dental procedures are very similar. They restore decayed or worn out teeth. They made out of the same material, porcelain or ceramic. They have the same durability. The difference between the two is how they fit into the tooth and the amount of tooth structure they may replace.

They both are cemented inside the tooth. Onlay, unlike inlay, covers one or several cusps (the raised part of the tooth) and extends to the occlusal surface.

Dental onlay vs. crown

Both onlays and crowns are used to treat extensive areas of decay, but crowns are designed to surround the entire tooth while onlays covers only the compromised portion. In the past, there were only two ways to restore decay either a metal filling or a crown. Now with advancements in cosmetic dentistry, ceramic onlays can restore the teeth that in the past would have required crowns. By placing onlays instead of crowns dentists are now able to save the tooth without removing so much of the tooth structure. Crowns are still recommended to strengthen teeth after a root canal therapy and to restore broken teeth.

Dental bonding vs. veneers

Bonding is typically less costly than a veneer. The bonding procedure is completed in a single visit, while veneers require two visits – one to prepare the tooth and make an impression that’s sent to a dental lab, and the second visit to apply the veneer. But bonding resin is as strong as the porcelain used in veneers, which means it will not last as long. It stains, unlike a porcelain veneer.
