To treat a cavity your dentist will eliminate the decayed portion of the tooth then “fill” the area on the tooth where the decayed product was eliminated.
Fillings are likewise used to fix broken or broken teeth and teeth that have been worn down from abuse (such as from nail-biting or tooth grinding).
Main Types of Dental Fillings: Pros and Cons Review
- Made of: A mixture of silver, tin, zinc, copper and mercury. Mercury is almost 50% of the mixture.
- Types: Conventional (non-bonded).
- Used for: Fillings in back teeth.
- Lasts: At least 10 years, normally longer.
- Costs: The least costly kind of restorative product.
- Amalgam fillings are strong. They can stand up to the forces of chewing.
- They are less pricey than the alternatives.
- Amalgam fillings can be completed in one dental visit.
- They are less sensitive to wetness during the filling procedure than composite resin.
- Amalgam does not match the color of your teeth.
- Amalgam fillings can corrode or taint with time. This can cause discoloration where the filling fulfills the tooth.
- A conventional (non-bonded) amalgam filling does not bond (hold together) with your tooth.
- The cavity preparation (the “pocket” in your tooth) developed by your dentist needs undercuts or ledges to keep the filling in place. Your dental expert may need to get rid of more of the tooth to create a safe pocket.
- Some people might be allergic to mercury or be concerned about its effects. Research reveals that the amount of mercury exposure from fillings resembles what people obtain from other sources in the environment.
- Made of: A mixture of plastic and great glass particles.
- Types: Direct and indirect. Direct fillings are put by your dental professional using a bright blue light that solidifies the soft material. For indirect fillings, your dental expert prepares the tooth and takes an impression of it. A laboratory or the dentist then will make the filling from the mold. During a second go to, your dental practitioner seals this filling into location.
- Used for: Little and big fillings, particularly in front teeth or the noticeable parts of teeth; likewise for inlays.
- Lasts: A minimum of 5 years.
- Expenses: More than amalgam, but less than gold.
- Your fillings or inlay will match the color of your teeth.
- A filling can be completed in one dental visit. An inlay may require two sees.
- Composite fillings can bond directly to the tooth. This makes the tooth more powerful than it would be with an amalgam filling.
- Less drilling is involved than with amalgam fillings. That’s since your dentist does not have to shape the space as much to hold the filling securely. The bonding process holds the composite resin in the tooth.
- Indirect composite fillings and inlays are heat-cured. This step increases their strength.
- Composite resin can be used in combination with other materials, such as glass ionomer, to supply the benefits of both materials.
- Composite resins cost more than amalgam fillings.
- Although composite resins have actually ended up being stronger and more resistant to wear, it’s unclear whether they last as long as amalgam fillings under the pressure of chewing.
- The composite may shrink when positioned, producing spaces in between the tooth and the filling. This can lead to more cavities in areas where the filling is not making great contact with your tooth. The shrinkage is reduced when your dental expert places this kind of completing thin layers.
- These fillings take more time to location. That’s due to the fact that they are usually positioned in layers. The increased time and labor involved also contribute to the higher cost.
- Indirect fillings and inlays take at least two visits to complete if your dental expert is not prepared to make the inlay while you wait. Your dental practitioner takes impressions at the first visit and positions the filling or inlay at the second go to.
- Made of: Gold alloy (gold combined with other metals).
- Used for: Inlays and onlays, crowns.
- Lasts: A minimum of 15 years, usually longer.
- Expenses: More than a lot of other materials; 6 to 10 times more pricey than amalgam.
- Gold doesn’t corrode.
- Some individuals like the gold color much better than the silver color of amalgam.
- Gold fillings are long lasting sufficient to hold up against chewing forces. They last longer than all other filling products.
- You need to visit the dental practitioner at least twice to get a gold filling. At the first check out, the dentist makes an impression of your tooth and positions a temporary filling. The gold filling is made from the impression. It is positioned at a 2nd visit.
- The cost is high because of the high cost of gold and the work involved.
- If gold and amalgam fillings are right beside each other in your mouth, an electrical current can result from interactions between the metals and your saliva. This can cause discomfort, called “galvanic shock.”.
- Gold fillings are not tooth-colored.
- Made of: Porcelain, most frequently.
- Used for: Inlays and onlays, crowns, veneers, implants, and orthodontic brackets.
- Lasts: More than seven years.
- Costs: More than composite and as much as or more than gold, depending upon the filling.
- Ceramics are tooth-colored.
- Ceramics are more resistant to staining and abrasion than composite resin.
- Ceramics are more brittle than composite resin and can break.
- A ceramic inlay or onlay needs to be large enough to avoid it from breaking. This means that the tooth must be
- decreased in size to make room for the additional bulk.
- Made of: Acrylic and a component of glass called fluoroaluminosilicate.
- Types: In a standard filling, the material sets without a bright light. Resin-modified or hybrid composite glass ionomer fillings are more powerful than traditional ones. A brilliant blue light is used to set the material.
- Used for: Glass ionomer is used most typically as cement for inlay fillings. It also is used for fillings in front teeth, or around the necks of your teeth, or in roots. As filling material, glass ionomer is typically used in individuals with a great deal of decay in the part of the tooth that extends below the gum (root caries). It is also used for filling baby teeth and as a liner for other types of fillings.
- Lasts: 5 years or more.
- Costs: Similar to composite resin.
- Glass ionomer matches the color of the teeth, but not constantly as well as composite resin. Resin-modified glass ionomer is normally a much better match than conventional glass ionomer.
- Glass ionomers launch fluoride, which can help protect the tooth from further decay.
- Glass ionomer remediations bond (stick) to the tooth. This assists to prevent leak around the filling and more decay.
- Standard glass ionomer is substantially weaker than composite resin. It is much more likely to wear or fracture.
- Traditional glass ionomer does not match your tooth color as specifically as composite resin.
- A resin-modified glass ionomer filling have to be applied in thin layers. Each layer must be treated, or solidified, with a special intense blue light. Then the next layer can be included. This makes the tooth more powerful, however can extend the time of the dental appointment.
