Dental Inlays

An inlay is defined as a restoration, which has been created out of the mouth from gold, porcelain or any other metal and after that cemented into the prepared cavity of the tooth.

Dental inlays are employed to treat teeth that have decay or damage positioned inside their depressed crown surfaces, between the cusps of the teeth. They can also be used to put back old or damaged metal fillings.

Inlays are made of different materials:

  • Gold
  • Porcelain
  • Composite

Dental Inlays

Inlays are positioned inside the cusps of damaged teeth while onlays extend downward the side of the tooth.

Inlays and Onlay

Dental Onlays

The onlay is basically an inlay that envelops one or more cusp and neighboring occlusal surface of the tooth.

Onlays are placed in much the similar way as inlays. Initially, an impression of the decayed tooth is made, and a temporary onlay is placed over the tooth. The impression is then sending to a lab, where a dental technician makes the onlay according to the tooth’s dimensions. When the patient returns to the dentist’s office, the temporary onlay is detached, and the permanent restoration is positioned on the tooth and firmly bonded using high-strength dental resins.

Similar to dental inlays, onlays can be produced from tooth-colored material, which makes them almost untraceable to the naked eye. Onlays also aid to preserve more tooth structure for the reason that their use requires negligible elimination a tooth’s surface.

Everything you need to know about Tooth Filling Material

Dental filling

Despite how well you look out of your teeth or how many times you brush or floss, at times you are constrained to build up cavity. Fillings can also be essential if  your teeth are damaged due to fracture or if you bite your nails or mince your teeth. In turn to preserve the tooth your dentist will eradicate the decomposed and fill in the cavity with one of the number of types of fillings.

filling materials

A filling is intended only to ‘fill’ a cavity and to close off further attack by bacteria. Advances in technology plus changing priorities for customers, have determined preferences for diverse materials.

Preferably, dental filling material must have the following qualities, in order of importance:

  • Dimensional stability (doesn’t transform shape eventually)
  • Physically sturdy (is able to defy wear and breakage)
  • Cosmetically pleasing (looks similar to a tooth)

It’s essential to make out the differences between the forms of filling materials. That way, if you require a restoration, you’ll appreciate how each material will work, how long it will last, and how it will look.

Types of Filling Material

Nowadays, numerous dental filling materials are obtainable. Teeth can be restored with gold; porcelain; silver amalgam (or tooth-colored, plastic, and materials called composite resin fillings).

1. Dental amalgam or “silver” fillings

1.	Dental amalgam or “silver” fillings

They are generally used to fill up back teeth. They are minimal cost and long lasting, but the color does not appear natural. little amounts of mercury can be free from amalgam fillings, which have bring about health worries in the past, but the minute amounts of mercury are usually not detrimental.

Advantages of silver fillings:

  • Robustness silver fillings last at least 10 to 15 years and generally live longer than composite (tooth-colored) fillings.
  • Strength – can endure chewing forces
  • Expenditure may be less pricey than composite fillings

Disadvantages of silver fillings:

  • Deprived Aesthetics – silver fillings don’t go with the color of natural teeth.
  • Annihilation of more tooth structure – healthy fraction of the tooth must a lot be aloofed to make a space big enough to grip the amalgam filling.
  • Discoloration — amalgam fillings can produce a grayish tinge to the nearby tooth structure.
  • chink and fractures– though all teeth enlarge and contract in the existence of hot and cold liquids, which in the end can result the tooth to crack or fracture, amalgam material — in evaluation with other filling materials — may encounter a widespread degree of expansion and contraction and show the way to a advanced prevalence of cracks and fractures.
  • Allergic Reactions — a minute percentage of populace, about 1%, are allergic to the mercury there in amalgam restorations.

Protocols comprise some or all of the following:

  • Use of high-speed suction throughout removal to considerably decrease the amount of mercury vapor that break out from the region right away surrounding the tooth.
  • Breathing oxygen or nitrous oxide during the elimination to bound inhalation of trace airborne mercury vapor.
  • Wearing a rubber dam for the period of removal of the amalgam fillings.

2. Gold fillings

These are made by means of a cast of your cleaned tooth, so it takes more than one visit to obtain a gold filling fixed, made, and placed. Gold is tough than amalgam but is also more costly and does not have a natural appearance. Previous to the preface of dental porcelain the top restorative material was gold. It has alike qualities to porcelain, in that it’s very firm and very strong.  on the other hand as the price of gold escalate each year, it is costly to manufacture and for the reason that it looks ‘gold’ it lack the cosmetic plea.

Gold fillings

Cast Gold Fillings

Benefit of cast gold fillings:

  • Durability — lasts at least 10 to 15 years and generally longer; doesn’t rust
  • Strength — can endure chewing forces
  • Aesthetics — some patients find gold more pleasant to the look atthan silver amalgam fillings.

Drawback of cast gold fillings:

  • Cost—gold cast fillings cost too much than other materials; up to 10 times elevated than cost of silver amalgam fillings.
  • Extra office visits – necessitate  at least two office visits to place
  • Galvanic shock — a gold filling positioned right away next to a silver amalgam filling may generate a jagged pain (galvanic shock). The communication between the metals and saliva results an electric current.
  • Aesthetics — the majority patients abhor metal “colored” fillings and wish fillings that go with the rest of the tooth.

3. Composite (white) fillings

These are completed in a single visit using layers of resin. Composite fillings are a fair option for visible areas as they look similar to your natural teeth, but they are not as burly as metal fillings so they might not last as long, specially on the back molars. Composite fillings fracture and crack more simply than metal, so the danger for recurring decay is advanced. Composite fillings are more pricey than amalgam but less costly than gold.

Composite (white) Fillings

Benefits of Composites:

  • Aesthetics — the shade/color of the composite fillings can be very much coordinated to the color of existing teeth. Composites are mostly well suitable for use in front teeth or perceptible parts of teeth.
  • Bonding to tooth structure — composite fillings in fact chemically bond to tooth structure, providing further support.
  • Versatility: besides used as a filling material for decay, composite fillings can also be used to fix flaked, broken down, or worn teeth.
  • Tooth-sparing preparation — at times less tooth structure requires to be aloofed compared with amalgam fillings when removing decomposed and preparing for the filling.

Shortcoming of Composites:

  • Lack of strength composite fillings wear out earlier than amalgam fillings; in addition, they might not last as long as amalgam fillings in the pressure of chewing and mainly if used for big cavities.
  • Extended chair time — for the reason that of the process to apply the composite material, these fillings can takes up to 20 minutes longer than amalgam fillings to lay.
  • Extra visits — if composites are used for inlays or onlays, more than one office visit may be necessary.
  • Chipping — depending on position, composite materials can break off the tooth.
  • Expenditure: composite fillings can charge up to two times the cost of amalgam fillings.

Other than tooth-colored, composite resin fillings, two other tooth-colored fillings subsist ceramics and glass ionomer.

Other Filling Types

1. Porcelain

It is the best filling material  you can use for a filling. If well-looked after following treatment, it will refurbish your oral health for the long-run, decades even, with good care. It’s also the most cosmetically alluring of all the materials.


for the reason that it’s intended exactly to fit your tooth, made outside the mouth, then bonded in, there is no chance for contraction as with plastic fillings.

Porcelain fillings are prepared outside of the mouth, either by a dental technician or CAD-CAM system, and after that cemented in. This new technology means that porcelain restoration can be made and cemented in the same appointment – so less time and less injections.

This material commonly lasts more than 15 years and can cost as much as gold.

2. Glass ionomer

Glass Ionomer

It is made of acrylic and a definite type of glass material. This material is most generally used for fillings beneath the gum line and for fillings in young children (drilling is still required). Glass ionomers discharge fluoride, which can help guard the tooth from further decay. Though, this material is weaker than composite resin and is more vulnerable to wear and prone to fracture. Glass ionomer usually lasts five years or not as much of with costs comparable to composite resin. The most recent ones have an still better lifetime and, when placed in suitable areas are equal to composites.

What Are Indirect Fillings?

Indirect fillings are like composite or tooth-colored fillings apart from they are prepared in a dental laboratory and entail two visits before being positioned. Indirect fillings are considered when not sufficient tooth structure relics to prop up a filling but the tooth is not so ruthlessly damaged that it desires a crown.

In the first appointment, decay or an old filling is detached. An impression is taken to trace the shape of the tooth being revamped and the teeth surrounding it. The impression is send out to a dental lab that will construct the indirect filling. A temporary filling is positioned to guard the tooth whereas the restoration is being made. During the second visit, the temporary filling is aloofed, and the dentist will test out the fit of the indirect restoration. Bestowed the fit is acceptable; it will be enduringly cemented into place.

There are two kinds of indirect fillings – Inlays and Onlays.

  • Inlays are alike fillings but the whole work lies within the cusps (bumps) on the chewing facade of the tooth.
  • Onlays are more widespread than inlays, casing one or more cusps. Onlays are at times called partial crowns.

Inlays and onlays

Inlays and onlays are more strong and last much longer than conventional fillings — up to 30 years. They can be made of tooth-colored composite resin, porcelain, or gold. Inlays and onlays weaken the tooth structure, but do so to a much lower amount than traditional fillings.

one more type of inlay and onlay — direct inlays and onlays — follow same method processes and dealings as the indirect, but the dissimilarity is that direct inlays and onlays are prepared in the dental office and can be positioned in one visit. The kind of inlay or onlay used depends on how much sound tooth structure leftovers and contemplation of any cosmetic interests.

What’s a Temporary Filling and Why Would I require One?

Temporary fillings are used under the following situations:

  • For fillings that entail more than one visit — for example, before placement of gold fillings and for definite filling procedures (called indirect fillings) that use composite materials
  • Following a root canal
  • To permit a tooth’s nerve to “quiet down” if the pulp became aggravated
  • If emergency dental treatment is required

What crops up when you get a Filling?

If your dentist makes a decision to fill a cavity, he or she will first remove the decay and clean the affected region. The cleaned-out cavity will then be filled with any of the variety of materials.

Whatever thing that looks unusual will then be intimately checkered with special instruments. Your dentist may also X-ray your whole mouth or a part of it. The type of treatment your dentist wants will depend on the degree of damage caused by decay.

What to be expecting During a FILLING

  • Local anesthesia– at  the start of your filling procedure you may be given local anesthesia to anesthetized the region around the tooth.
  • Tooth decay removal– then the dentist will engrave through the enamel by means of a drill to eliminate any decay. After the dentist take out the decay, the dentist will shape the space to prepare it for the filling.
  • Etching– for a bonded filling your dentist will etch the tooth with an acid gel prior to placing the filling.
  • Resin application– for certain forms of fillings the dentist will layer on the resin and solidify it using a bright light. This makes it burly.
  • Polishing– subsequent to the filling has been placed, your dentist will polish the tooth.

  • Chew leisurely and bite off calmly: Biting applies magnificent pressure on the teeth, and this can make them very painful after you get a filling. When chomping your food, take your time and try not to bite all the way through; this will avert your teeth from making strong contact. If doable, chew on the opposite side of the mouth from where your filling is.
  • Keep your mouth closed when chewing: For some populace, even cold air can set off pain in sensitive teeth. as a result , in addition being good manners, keeping your mouth closed when chewing will diminish the probability of cold air ingoing your mouth and causing you pain.
  • Omit sticky foods: Some fillings, mainly silver (amalgam) ones, take time to lay down after you depart the dentist’s office. Consuming sticky or gluey food can, in exceptional cases, extricate a new filling, so it’s best to shun them temporary.
  • Evade very hot or cold drinks: Moderate temperatures are less liable to trigger pain in sensitive teeth.
  • Pass on the sweets: Sugary foods and soft drinks activate sensitivity in some and may encourage bacterial growth in the region of the edges of, or even under, a new filling.
  • Don’t chew up nuts, candy or ice: Other than causing undue pressure on your teeth at the same time as they are still recuperating, biting hard foods can extricate a new filling that hasn’t yet well set. This is particularly significant for silver (amalgam) fillings, as they take longer to set than composite (tooth-colored) fillings.

Always go after your dentist’s advice concerning chewing tips, what foods to evade after your procedure and how long you are supposed to wait to eat solid foods after getting softer filling materials, such as amalgam.
